Earl | AI product engineer | London | On-site 4 days/week | Fixed term to Dec 2026

We’re hiring an AI-native engineer to work with Earl on a live project inside a Premier League football club. This is not an AI strategy role, and it’s not a chatbot demo job. You’ll work directly with people inside the club's commercial team, find valuable problems, and build production AI systems that are actually used.

We’re looking for someone who can move from vague problem → technical design → working product quickly.

You do not need football experience.

You do need strong product judgement, the ability to work directly with non-technical users, and evidence that you’ve actually shipped things.

We’re particularly interested in people who build with AI as their default way of working, rather than conventional engineers who have recently added an LLM API to their CV.

To apply, send me:

- A short intro - 2-3 things you’ve built What you personally did - How you currently use AI to build software - Location and availability

Strong candidates will do a paid practical working session.

Odin | Senior Design Engineer, Senior Platform Engineer — Edge Systems | Remote (US) | Full-time

Odin is the workforce visibility and compliance platform for critical infrastructure. We protect the world’s largest construction projects, data centers, and critical assets—from groundbreaking through post-turnover—by unifying physical access control, workforce compliance, video monitoring, and drone surveillance in one command center. We’re already on 500+ active projects with 100K+ workers, securing over $100B in construction value.

We’re hiring two hands-on senior builders:

1. Senior Design Engineer: Research, design, and build the interfaces people use to run jobsites. You’ll establish Odin’s design language and production design system, create coded prototypes with mocked states, and implement responsive, accessible screens across desktop, tablet, and mobile. We’re looking for someone whose portfolio demonstrates customer research, strong product and interaction judgment, and substantial production frontend engineering.

2. Senior Platform Engineer — Edge Systems: Build the software connecting jobsites to Odin’s cloud. You’ll work with cameras, access-control readers, rugged devices, local compute, and constrained networks. You'll own device integrations, video and event ingestion, buffering, synchronization, remote deployment, diagnosis, and recovery. We’re looking for production experience with edge or distributed systems, intermittent connectivity, third-party hardware or protocols, and software operating beyond a conventional cloud environment.

Our stack includes TypeScript end to end, Node.js and GraphQL, React and CSS, React Native and Expo, Postgres, Kubernetes on GCP, and Datadog. Design Engineering uses Figma and Claude Design. Edge Systems integrates with technologies including CCURE 9000, Avigilon, HID, Zebra, Esper, and Iru.

Both roles require strong ownership, operational maturity, mentoring, and using AI to accelerate work without outsourcing judgment. These are individual-contributor roles and include periodic jobsite travel.

Sitewire | Full-Stack Software Engineer | Full-Time | $130-200k USD | 0-0.1% Equity | Remote (US only)

I'm the head of engineering at Sitewire, a construction finance platform that helps lenders and real estate investors track projects, automate work verification, and speed up payments. Our small, fully-remote team has built a profitable product that's expanded organically 3x per year, mainly through word of mouth. We're now looking to roughly double the size of our engineering team as we enter our next phase of growth.

We're looking for smart, pragmatic full-stack engineers who operate with a high degree of autonomy and ownership. This is not a ticket factory: you'll be working directly with our PM to turn product briefs into new platform features and will have a hand in shaping the architecture and design of the things you build.

Our current stack is React and React Native on the client side with Postgres as our database. Our web app and API are currently powered by a Ruby on Rails monolith that we're gradually migrating off of. You don't need experience with Rails and it's not what we're hiring for: we're looking for React experience + solid backend engineering experience with any modern language.

Our interview process is pretty simple: a phone screen/behavioral interview, a 1-hour coding challenge that you can complete as either a live session or a take-home (your choice), and a presentation on a project you designed and feel particularly proud of (or think is particularly interesting).

If you're interested, please fill out this form and I'll be in touch: https://forms.gle/diVa5ScKJLYnW7u38

Joulent | Founding ML Platform Engineer, Energy Intelligence | San Francisco | HYBRID | Full-time | equity

We deliver multi-gigawatt power to AI data centers, and this is the founding hire on the team that forecasts load and market prices. You own the whole spine: ISO/RTO market feeds, weather and plant telemetry through feature store, serving, drift detection and the model gateway.

Not a scale problem — the data is rich, not petabyte. Feeds land late and get revised after the fact without ever throwing an error, so the failure mode is a price series quietly wrong for three weeks behind a forecast that looks fine. The work is trust infrastructure: lineage, freshness SLAs, point-in-time correctness, eval gates that can block a model.

Python, SQL, Airflow, containers, IaC. 5+ years on production data and ML platforms; energy background welcome, not required.

JD: https://joulent.github.io/careers/ — sandy.suresh@joulent.com

Looking for: expert-level kdb+/q, engine internals, query planning/optimization, C API extensions, performance analysis. Nice to have: exposure to hardware acceleration concepts.

Apply: email amir@silicon45.com with your resume and a short note on 1-2 performance-critical kdb+ systems you personally built or optimized.

Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles

Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.

We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.

Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns.

Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.

Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.

Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.

Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.

Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.

To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P Thanks for your time!

Arcforma AI (arcforma.ai) | AI Engineer (Marketing / Construction / Fashion & Luxury) | REMOTE (US only) or ONSITE NYC | Full-Time $80k-$120k + equity, or Contract $50-$150/hr | jobs@arcforma.ai

We build production AI systems inside other people's companies: hotel groups, automotive retail, creative agencies, consumer brands. One industry at a time, sitting next to the operator whose job the system changes. Very little of it is generic LLM plumbing.

Two ways in.

CONTRACT, PROJECT-BASED ($50-$150/hr). For people who already have the domain. A scoped first project, typically three to six weeks. This is most of what we need right now, and it is how we would rather start with anyone senior.

FULL-TIME ($80k-$120k + equity). For strong engineers earlier on who want to go deep into one industry with us instead of staying a generalist. We teach you the vertical. You bring the engineering.

Pick one track. Depth in one beats a tour of all three.

MARKETING. Lifecycle and CRM automation, brief-to-asset pipelines, creative variants with brand guardrails that hold, attribution. You have fought HubSpot, Klaviyo, and the Meta and Google ad APIs.

CONSTRUCTION. Invoices in, mapped to contracts, schedule of values, and cost codes, back out as pay applications. Then RFIs, submittals, change orders, schedule impacts. You know why generic invoice parsers stall when half the input is handwritten. Weighted toward ex construction tech and people who have run operations at a GC or a sub.

FASHION AND LUXURY. Merchandising and assortment planning, tech packs and PLM, Shopify Plus and PIM, allocation, replenishment, demand forecasting, size curves, markdown optimization, clienteling, creative workflows.

ALL TRACKS: You own a system end to end (data in, evals, an interface the client actually opens), and you can sit with a non-technical operator and leave with the right spec.

TO APPLY: email jobs@arcforma.ai with the subject line

HN | TRACK | Your Name | your applicable background in one short line

TRACK is MKT, CON, or FASH. For example:

HN | FASH | Jane Okafor | 6 yrs building allocation and planning systems at a DTC apparel brand

The body: what you shipped that is applicable to the role, a link we can open (GitHub, a writeup, a demo), LinkedIn, and your timezone plus whether you want contract or full-time and at what rate.

Every application gets a reply within five business days. 20 minute call, paid trial on real work, then a project or an offer.

We are looking for a candidate with a generalist background in software development, including 5+ years of experience on Platform Engineering, DevSecOps, Site Reliability Engineering (SRE), or MLOps teams. You'd be joining a small cross-functional team and have the chance to make critical contributions. Our ideal candidate has a passion for automating ops, troubleshooting infrastructure, and creating first-class developer experiences. On top of that, expertise with the following (or similar) tools/technologies is a strong signal of fit: Kubernetes, Prometheus, Grafana, Terraform, AWS, GitHub Actions, PostgreSQL, Node.js, Ruby on Rails, Nix, and Docker.

We say that up front because it is the first thing worth knowing.

Rankwise | Head of Growth | https://tryrankwise.com The infrastructure layer for AI search.

Cologne, Germany | UMH | Product Engineer | Full-time | 55 - 85k EUR | ONSITE (part remote)

Hi, Alex and Jeremy here from UMH.

8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.

What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.

Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.
