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 :-)

Infor is huge in the ERP space and dates back to bigger iron days(mainframe and midrange - IBM AS/400). They acquired a lot of smaller players over the years which might be way they are somewhat unknown these days unless you date yourself to that era.

I have used Infor. i have not administered it.

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

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US)

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.

We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.

We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

Fusionbox: Leet-code style interview where you'll be expected to write correct, then optimized code in three different languages while a team of four watches. Owner calls it "pair programming."

Ooof, thanks for the heads up.

TextQL | Senior Software Engineer (FT) | ONSITE | New York City | $200k Salary - $400k Total Compensation

Company: TextQL is working to drive the unit cost of a data-driven decision down to zero. We're building the agentic data lakehouse – finding trustworthy answers to hard questions from messy enterprise data without configuring schemas, moving data, or lengthy implementation roadmaps.

Roles:

* Platform: today, no one stakes their job on AI-generated queries. You'll build the system that changes that—giving agents the context to query enterprise data correctly, and the guardrails to prove it.

* Infrastructure: sandboxes are not enough for agents to work with enterprise data. You will develop reliable infrastructure for the first data platform designed to be operated agent-first – ETL pipelines, Trino clusters, and systems that let agents spin up infrastructure on their own.

Stack: Go, Haskell, TypeScript, DuckDB, Trino, PostgreSQL, Redis, Kubernetes, AWS

Perks: 21 days PTO, free lunch, 5% 401(k) matching, top-tier health insurance, visa sponsorship

How to Apply: email gabriel@textql.com with the most significant technical challenge you have solved, GitHub if you have one, and LinkedIn and/or resume (PDF).

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?

Language REACTOR

REMOTE mostly, but I travel often (Europe, Asia) and it's good to work in person time to time.

We make software for learning languages. The focus is on making tools, rather than content. But actually, the line between code and content is blurring with LLMs.

I am the main coder on the project and I'm looking for a coding partner to help spread the load and allow more ambitious scope. Project is solid financially.

Most of the codebase is fairly decent Typescript. Backend knowledge a plus.

I need someone with sound judgement and taste that can plan and execute independently, but that also can communicate and coordinate complex changes well. Ingenuity and resourcefulness.

I use Claude/Cursor extensively.

I'm quite interested to hear from you if you have a project that overlaps in scope with Language Reactor.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

https://www.monumental.co/jobs

Would you hire US citizens willing to move?

Not OP, but Monumental is a registered sponsor for highly skilled migrants, which is applicable for the roles listed. So in short, if you got an offer you could be sponsored.

Thank you for sharing. I now also have a better idea of what wording to look for in the future.

Yes

Thanks!

Probably Austin and Seattle.

Location: San Jose, CA (see posting for details)

We’re building Wave, a high-performance GPU programming language and compiler for machine learning workloads. Wave combines a Python-embedded DSL with an MLIR-based compiler stack to give engineers explicit control over GPU kernel performance.

We’re looking for a low-level GPU performance engineer to own end-to-end performance of Wave’s kernels.

You’ll work on

• Hand-tuned GPU kernels (GEMM, Attention, MoE, decoding)

• Instruction-level optimization: memory, registers, scheduling, wave/warp behavior

• HIP/CUDA, GPU intrinsics (MFMA/MMA), and inline assembly • MLIR dialects, lowering pipelines, and performance-critical compiler passes

• Profiling via disassembly, counters, rocprof/Nsight

Strobe | Software Engineer | Brooklyn, NYC | ONSITE | Full-time | $120k–$250k + equity

We’re building a distributed, software-defined power plant: buildings, batteries, EVs, and on-site generation buying and selling power in real time. Think cloud control plane + embedded hardware + energy markets.

Small, high-performing team. No layers. You’ll own systems end-to-end: design → deploy → on-call.

We’re looking for *fungible generalists*, not narrow specialists. Strong fit if you’re comfortable with: - AWS-heavy backend work (Lambda, APIs, GraphQL, data pipelines) - Operating real-time production systems - Python / TypeScript (Rust a plus)

Depending on fit, you might work on: - Telemetry & control over unreliable networks - Embedded Linux / RTUs (Modbus, BACnet, DNP3) - Market-facing systems and optimization - Operator UIs with real-time streams (React)

Requirements: - Strong production experience - Systems mindset, bias to shipping - Willing to be onsite 5 days/week at Newlab (Brooklyn Navy Yard) - Not remote

Fast pace, direct feedback, real ownership. This is not a 9–5.

Veho | ONSITE / HYBRID 3 days per week | NYC or Boston | No Visa | https://shipveho.com/careers

Hi there! At Veho, we don't sell software. We ship packages. Lots of them. We have all of the interesting problems that crop up when running twinned distributed systems in AWS and the real world. It's pretty great.

We're hiring staff-level folks (L4+) in NYC and Boston: Data Scientists, Data Engineers, Mobile Engineers, and Backend Engineers (typescript).

Personally, I'm hiring a Staff Data Engineer with the depth of experience to be a technical lead and mentor for the Data Platform team, while also shipping code. You will need to understand distributed data systems both intellectually and at an instinctive, emotional level. You should have Opinions about the wild boar book. You should probably also be comfortable writing and debugging English, SQL, and Python.

If that sounds like you, I really want you to apply for the Staff Data Engineer role on our career page. Our inbound applications are reviewed by humans.

With apologies that our first interaction requires this silliness: including one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box will heavily bias me towards believing you are a human being. That's more of an advantage than it may seem! It's worth the thirty seconds. It would also speed things along if you populate the "Location" field to confirm you are aware this is an in-office role.

Tower | Senior/Principal Software Engineers | London, UK / Berlin, DE | https://jobs.tower.dev

We're a Python-native serverless platform built on Apache Iceberg with powerful ETL and Lakehouse management tools. We integrate seamlessly with enterprise systems and make companies more nimble by letting them choose the best engine for each job while maintaining full data ownership.

We're focused on hiring developers that love the data ecosystem, are interested in really hard distributed systems problems, and working on dev tools.

Upway | Software Engineers (All levels), Senior Product Designer, Senior Product Managers | Full-time | Paris (ONSITE)

We’re building the biggest second-hand bike shop in the world.

Upway is the leading marketplace for refurbished e-bikes across Europe and the United States.

In 3 years, we grew from 0 to $200M GMV. The tech team grew from a small senior core to ~12 engineers in 2025, and we plan to grow to ~30 engineers in 2026. We also raised a $60M Series C at the end of last year to support the next phase of the company.

This is not a SaaS. We operate warehouses, handle real inventory, and build software that connects logistics, product, and marketplace dynamics at scale.

We’re looking for engineers and product people who like tech as much as business, people who want ownership, enjoy making product and business trade-offs, and care about outcomes, not just systems.

We work with a Shape Up–inspired methodology that gives teams real ownership: shaping problems, building solutions, shipping, and learning from real-world impact.

Stack: TypeScript | NestJS | React | Shopify | PostgreSQL | GCP

Why it’s a great time to join:

- The organization is switching gears: bigger ambitions, broader scope, more responsibility.

- The challenges are growing with the team: product, marketplace, and operational complexity.

- High ownership environment where engineers influence technical and business decisions.

- Paris on purpose: at our current pace, working in person is a real advantage.

Hack Club | Quality & Integrity Lead, YSWS | Shelburne, Vermont (USA) | ONSITE

Hack Club (https://hackclub.com / https://github.com/hackclub) is a nonprofit where 1,000s of teenagers ship real projects — games, hardware, websites, apps — and we send them free stuff in return. 100k+ teens, 140 countries. Our motto is "by teens, for teens" and we operate with radical trust and transparency.

Every month, thousands of projects come through our You Ship We Ship programs. Program authors do the primary reviews. We need someone to QA the reviewers — a second set of eyes who can tell us: are they making good calls? Catching the fake projects? Being too harsh on legitimate ones?

Responsibilities:

- Spot-check approved projects (random sampling)

- Audit reviewer consistency and catch patterns

- Define what "high quality" actually means and document it

- Train program authors to make better decisions

- Handle appeals and investigations

- Build systems that work at 100k projects/year

You'll still do plenty of hands-on review — you can't spot-check effectively without understanding the projects deeply. But your mission is ensuring the integrity of the entire process, not being the bottleneck for each submission.

$55-70k. 4 weeks PTO. Health/dental/vision. Based in an 1800s building in Shelburne, Vermont. Full details: https://hiring.hackclub.com/38523

The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction.

We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.

- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals

- A balance of wisdom from experience and optimism about the future

- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)
