Small boutique consulting | Remote (US) (some est meetings) | part-time/flexible/1099

Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses.

We are seeking a developery-data person with experience specifically with CloudSuite Distribution by Infor for one of our clients. It may be a bit of a shot in the dark, but if you have worked with this *specific* ERP system before, we'd be eager to talk to you. Reach out at "ekib.eikooc@rofni".reverse() Please include your experience in your email body/subject as we will have to quickly triage out most of the spam.

PS. Each time I post here I get ~500 emails, almost all are low effort that don't meet anything I am looking for, sometimes for months in the future. I expect it to be even worse as LLMs gain traction. I've hired 4 people from past posts (check my history if you want!), but it can take some time dig through everyone so I apologize to legitimate interests.

Just wanted to mention it was nice to see such a down to earth posting. Unfortunately, I've never even heard of the ERP you mentioned, but you sound like a good company to work for :-)

This is a wholesome job post. Reminded me there’s a human somewhere in the loop. I hope you find the right person.

SEEKING PARTNER | Bay Area | Applied Research Lab

Not a job. I’m exploring alignment with a potential partner.

I’m a systems builder (CS/infra founder; shut down my last startup) who spent the past two years going deep on foundational math that most engineers (and I guess many mathematicians) tend to ignore, largely at an nLab level, because standard abstractions stop composing.

I’m working toward a small, private apply-focus lab to bridge native CS intuition (computation, scale, systems) with structural, information-theoretic mathematics. The focus is composability, learning, universality, and complexity, with the intent to build, not publish.

The approach is unconventional, but intentional: staying close to real systems while reworking foundations when existing methods stop composing.

Looking for a self-funded generalist comfortable crossing CS, math, and theory that's interested in structure, information, ethics, and long-horizon work.

I'm interested in chatting. Have a way to contact you?

You’ll be a key contributor, helping bring our next generation of mobile solar factory to life.

Come work with us if you love:

* Fast-paced prototype development with software and hardware components

* Making a positive climate impact through your work

* Hacking on massive construction equipment!

Cloudflare | New York City, Austin, London, Lisbon, San Francisco, Seattle | Full Time

I’m hiring for some (IMHO) really fun product manager roles on Cloudflare’s Developer Platform (workers.cloudflare.com) - Workers Runtime - Set vision for our V8 isolate based runtime that lets people deploy JS, TS, Rust and Python to the globe in seconds with great dev ex. - Containers - Help build our new containers platform into the best place for both agent Sandboxes and stateless global apps. - AI Agents - Define what Agents on Cloudflare look like: from our AgentsSDK, to Sandboxes, to MCP Servers, “Code Mode” (see our blog) and more.

We’re a really technical group, and tend to like product managers that can straddle the line between engineer and PM. You should be able to set high-level vision, understand architectural constraints, and be technical enough to really deeply understand our users (developers).

MiLaboratories | Bilbao, Spain | ONSITE | VISA SPONSORSHIP | RELOCATION SUPPORT

We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—a platform that processes terabytes of genomic data to accelerate biological discovery and drug development.

We are a deep-tech research lab, not a typical SaaS. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + biological nuances) requires high-bandwidth, in-person collaboration.

We are hiring for three core roles:

1. Senior TypeScript Engineer (Desktop Platform / SDK): This is not a dashboard or a simple web GUI. You will build the architecture of our Desktop Platform—a high-performance local application that acts as the "OS" interface. You will deal with complex state management, massive data throughput, and bridge directly with our high-performance Rust data layer. We need someone who treats the browser engine as a runtime for heavy applications, not just for websites.

2. Senior Go Engineer: You will build distributed systems for high-load genomic data processing. This is not CRUD. We need someone who understands memory management, concurrency, and algorithmic efficiency at scale.

3. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing production blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology (Builder profile, not just analyst).

The Offer:

Comp: Top-tier EU salaries (~€90k - €120k).

Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions).

The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin.

Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have."

Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search).

Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.

Process: No HR screening. You will talk directly to the engineering team.

Email me (I am the CEO): stanp@milaboratories.com. Please mention "HN" in the subject and include your GitHub.

PostHog | Full-Time | Product engineers, backend engineers, Technical AMs | REMOTE (all remote) | Hiring GMT-8 to GMT+2

* we have a public handbook (posthog.com/handbook) if you want to learn how we work, pay and more in complete detail.

* we are growing through more autonomy and transparency not through process.

* we have a ton of scale and a bunch of super interesting technical problems to solve

* we're building 20 more products over the next couple of years, so you could end up building one of those

* public compensation calculator! see immediately what you'd get paid

* we're hiring: product engineers, clickhouse operations engineer, backend engineers, product managers, technical account managers and technical customer success managers.

https://posthog.com/careers

Very cool on the transparency! I was surprised to see Spain (all one bucket) has higher salaries on your calculator than places like Edinburgh.

We have a lower bound on our location based pay which is a percentage of salary in SF, which applies to both those locations. We fixed the currencies a while ago (so people's pay don't fluctuate up and down in local currencies), which is why those two locations have different pay now.

At Peregrine, we are transforming the way organizations engage with their data, making it easily accessible and immediately actionable for those who need it, when they need it most. SF / NYC / DC | In-office | Full-time | $130,000 - $275,000

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability.

The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!

Our products:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

  *Flaky Tests: Detect and eliminate Flaky Tests.

Chestnut | Hiring Senior / Staff Software Engineers | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds software insurance carriers actually run their business on. We replace legacy, manual distribution systems with real-time data, automated workflows, and AI-driven tooling in a space that hasn’t changed much in decades.

This is product engineering. We ship to real customers, operate what we build, and spend time fixing the sharp edges that show up in production.

You’d work on backend-heavy product features around onboarding, compliance, payouts, and integrations. A representative problem: building a commission payout flow that ingests messy carrier data, applies complex rules and hierarchies, explains results to ops, and executes payouts that must reconcile cleanly with finance—while handling holds, chargebacks, retries, and partial failures.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS, LLM tooling.

Roles:

- Senior Software Engineer – Product / Backend (https://jobs.ashbyhq.com/Chestnut/fbbb7601-3d31-48b4-8639-75...)

- Staff Software Engineer – Architecture & Scale (https://jobs.ashbyhq.com/Chestnut/f28c5ee5-12aa-4e7b-b0ea-f5...)

- Engineer – Agent Orchestration & Workflow Systems (https://jobs.ashbyhq.com/Chestnut/075a0010-bfa5-489e-8808-e9...)

Hybrid in SF and Seattle.

Vidably | Founding Engineers and Designer | San Francisco (SF) | Full-time | Onsite

(I only have one JD posted publicly, but I'm hiring broadly for eng + design): https://www.linkedin.com/jobs/view/4330646312

I'm founder of Vidably and just closed a $1.5M pre-seed last week.

AI agents are about to orchestrate trillions in commerce, but today they shop on thin data: product specs, studio photos, and text reviews. Agents need evidence, not marketing. Today, the most influential product evidence lives on TikTok and Reels, outside the surfaces brands control and agents can use. Vidably puts verified buyer video directly onto e-commerce product pages through a lightweight widget. We capture that video post-purchase and link it to real purchasing outcomes. Every video is SKU-linked and structured so shopping agents can reason over it.

We're already seeing organic pull from creators and expansion from brands.

Tiger Data (FKA Timescale) [ Global | 100% Remote | Multiple Roles: Eng, GTM, Support + more ] We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.

Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.

This is not a reinvention: it’s a reflection of how we already serve our customers today.

TigerData is growing! Check us out: https://www.tigerdata.com/careers

Partner Sales Manager, AWS - https://www.tigerdata.com/careers/c4980e2e-3b9e-4f97-9a2a-cf...

I use TimescaleDB every day.

Being able to ask questions to an LLM copilot about patterns across several billion rows, 140GB of time series data, like how the market reacts 15 minutes, 1 day, and 1 week after Federal Reserve press releases, using time_bucket() and other aggregation functions with compressed chunks, and having the copilot generate the queries and run them fast, is going to be game changing. I can ask to write a script to scrape the press releases, to run them through another agent to classify them (hawk, dove) and use that information in the time series analysis.

Even though that exploration has not produced any actionable, tradable results for me, which is why I am sharing it, eventually TimescaleDB will be one of the most important tools in fields like medical research. A researcher will be able to ask in natural language for statistically significant patterns in the data, and LLM agents will query it quickly while taking advantage of all the TimescaleDB optimizations.

VIVA Finance | Atlanta, GA (In Person)| Back-end Software Engineer

Target Experience Level: 2-4 years of professional software experience

VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.

We are a VC backed company and have been in business for 6 years. We have been profitable since mid 2024 and are dramatically ramping up origination volume in 2026. We are hiring an additional backend engineer to support the larger transaction volume, as well as to support new products we are launching to diversify our revenue stream (including automobile refinancing and a credit builder account). You will join our engineering team of 11 and work in a dynamic environment where you are frequently writing net new code to directly support business objectives.

Our tech stack for the back-end is fully on AWS, using Lambda and ECS for compute and Typescript as the language, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our office on the Atlanta Beltline (next to Krog Street Market). VIVA does not provide visa sponsorship, so please have authorization to work in the USA.

Send an introduction to our hiring manger (alexa@viva-finance.com) with a resume and we will be in touch!

Goody | Remote | $150–250K + equity and benefits | North/South America | Full-time

I'm Mark, the technical co-founder and CTO at Goody. We're building a gifting product that every business can use to recognize employees, retain customers, and accelerate sales. Despite being something everyone does, gifting is one of the areas of commerce yet to be disrupted, and we're working on building the best and most delightful product in this space.

Our product is used by Google, Stripe, Anthropic, Meta, NBCUniversal, Notion, and others, and we also offer a developer API for commerce. Tech stack is Ruby + React + TypeScript, though we're flexible on backend language if you know Python or Node.js better. All roles are full-stack.

We're coming off of a big year and planning for scale in 2026. We have a few new roles to accelerate our growth.

• Staff Software Engineer ($200–250K) — for those who ship at a startup pace and have a great eye for detail

• Senior Software Engineer, Customer Engineering ($150–200K) — if you like to hear a customer request in the morning and tell them it’s shipped in the afternoon. US and Canada only for this one

• Senior Software Engineer, Growth ($150–200K) — be the engineer who has the most direct impact on our growth

• Data Analyst ($80–140K) — build models to help power decision-making across our business (not a dev role but thought I'd include it)

We're looking for people who have great startup energy, want to win, and bring great vibes to our tight-knit team. Great time to join since our offsite in London is happening soon (we're US-based, this is our third international offsite).

Waypoint AI | Senior Backend, Fullstack, Frontend | Prague + REMOTE (CZ) | Full-time | Equity

We're building Chip — an AI support engineer that autonomously triages, routes, and resolves complex technical support cases. Think: a teammate that reads every Jira ticket, every Intercom thread, and every runbook, then actually acts on them.

Czech-American B2B startup, raised $3.1M. Already in production with Volvo, ClickHouse, and others.

We're a small eng team where early architectural decisions still matter. We use AI daily as a collaborator (Claude Code) — not as a gimmick, but because it genuinely makes us faster. We value craft, ownership, and shipping in small slices.

Stack: Django + Django Ninja, Postgres, Dramatiq (background jobs), React/Next.js/TypeScript/Tailwind.

Hiring for three roles:

Senior Backend Engineer (AI Systems) — Own APIs, data pipelines, and durable workflows. LLM product experience (evals, cost/latency, vector search) is a plus. https://mywaypoint.ai/open-positions/senior-backend-engineer...

Fullstack Engineer — Backend-heavy with enough frontend to be dangerous. End-to-end ownership from schema to UI. https://mywaypoint.ai/open-positions/fullstack-engineer

Frontend Developer — Build interfaces that make complex AI feel simple. React/Next.js/TS/Tailwind. Product-minded, not just pixel-pushing. https://mywaypoint.ai/open-positions/frontend-developer

Office in Prague 7 (Holešovice), remote-friendly. Competitive CZ-market comp + meaningful equity.

To apply: joinus@mywaypoint.ai — include a project you shipped end-to-end and how you use AI tooling in your workflow. Mention HN.
