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.

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.

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.

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.

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?

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!

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.

Neo.Tax | Senior Full-Stack Engineer | Remote (US Timezones) | Full-time

Our stack is TypeScript/Node.js/React/SQL with distributed data pipelines processing millions of records from Jira, GitHub, payroll systems, and accounting software.

We're hiring a Senior Full-Stack Engineer to join our 7-person engineering team. You'll build our software capitalization product end-to-end—designing data ingestion pipelines, modeling flexible schemas for diverse customers, building integrations with third-party APIs, and shipping customer-facing features that finance teams use monthly.

What we're looking for:

- 7+ years full-stack experience with TypeScript, Node.js, React, SQL, and distributed systems - Ownership mentality—you can take product requirements and break them into iterative deliverables that ship value quickly - Comfortable with ambiguity and greenfield problems - Strong fundamentals (we use AI as a multiplier, not a substitute for engineering skills)

*Why join now*: We're preparing for Series B with 2x YoY growth, multiple profitable months, and real product-market fit. You'd be joining at a stage where early employees have outsized impact on trajectory.

Salary: $190k–$210k + equity. Remote-first, but we prefer timezones that overlap with Mountain View, CA.

Apply: https://apply.workable.com/neo-tax/j/BD05B5C7B1/

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.

Annex Risk | Backend + Data Engineer | Bay Area, Austin | Full-time

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. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.

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.

We’re looking for:

- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- ~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)

- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)

- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

We're looking to build our in-person team in NYC but also open to remote!

Unto Labs | San Francisco, CA | ONSITE (Hybrid OK), REMOTE (US) | Full-Time Unto Labs is developing the Thru Layer-1 blockchain (https://thru.org) We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers.

Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. You can write smart contracts and programs in any LLVM compatible programming language and reason about a standard ISA in RISC-V. Components are developed in C for maximal control over performance and resource usage.

We believe there is a unique window of opportunity to developer fairer, more accessible, and more global financial products on resilient public blockchains.
