About CircuitHubCircuitHub is reshaping electronics manufacturing with The Grid, a factory-scale robotics platform that makes small-batch, high-mix electronics assembly radically more efficient. Think semiconductor-fab precision applied to the chaotic world of prototyping and low-volume production: a 10x throughput improvement in one of the world's most foundational industries.

We've raised $45M from top-tier investors including Plural, Y Combinator and Google Ventures, and we're already profitable. Our customers include a major EV maker, a top AI lab and many of the worlds largest companies.

The Grid isn't a prototype. It's live, scaling fast and delivering real revenue, and we're building the team that will scale it further.

The RoleCircuitHub makes electronics on demand. Engineers upload a circuit board design; we buy the parts, build the board in our own robotic factory and ship it. More and more of that business is now run by AI agents, and we want you to help build them.

These aren't chatbots. Our agents have real jobs:

They inspect boards. An agent checks camera images of every panel we build for wrong, rotated or missing parts.

They program robots. Agents read datasheets so our pick-and-place machines know how to handle each new part.

They watch the factory. They spot stray parts in robot storage, diagnose printer faults and clear stuck machines.

They run the back office. They book supplier invoices, chase late orders, explain quotes and triage bugs.

They write our code. Most of what our team ships starts in an agent session.

What you'll doFind a process people still do by hand and automate it end to end: decide what needs judgement and what needs plain code, build the tools, and prove it works before it runs alone. Then make it cheaper, faster and right more often. You'll also improve the platform every agent runs on, and work closely with the people your work serves, from factory operators to finance.

What you'll do
Inspect boards. Improve automated optical inspection that finds missing, rotated and wrongly placed parts and bad solder, working alongside our AI agents.

Pick reliably. Train and deploy the models that find parts in bins and trays, centre them on the nozzle and catch a clumped or dropped pick.

Align precisely. Fiducial detection, calibration and image alignment for placements measured in fractions of a millimetre.

Build the data loop. Decide what to capture, build labelling tools, and turn operator verdicts into training data.

Go fast. Work with our high-speed cameras and GPU capture pipeline to move vision closer to real time.

Measure it. Track accuracy in production, find where errors come from, and prove every change against past results.

What we look for
You've shipped computer vision into production, beyond a notebook.

Strong software engineering in Python, C++ or a comparable language.

A mix of classical vision (geometry, calibration, template matching) and deep learning; you know when each is the right tool.

Experience with industrial or machine-vision cameras is a bonus.

You use coding agents to move faster and take full ownership of what they produce.

You like the physical world: lighting, lenses and …

What you'll do
Shape the customer experience. Upload, quoting, ordering and our board viewer on circuithub.com.

Make internal tools a pleasure. Our admin dashboard runs purchasing, planning, recruiting and the AI agents that do more and more of the work. Make dense, data-heavy screens clear and fast.

Design for the factory floor. Screens operators read at a glance while robots move around them.

Own the design system. Bring our brand, components and patterns together across web apps and machine screens.

Design for agents. Work out how people should review, steer and trust the work of AI agents.

What we look for
You've shipped full-featured web apps in TypeScript and React, and you can show us.

A real eye for design, both UI and UX. A portfolio we can look at matters more than a job title.

You enjoy owning a product end to end, from talking to users to deploying.

You use coding agents to move faster and take full ownership of what they produce.

Bonus: data visualisation, Elm or other functional languages, industrial or operator interfaces.

Overview
CircuitHub is primarily built using a combination of Haskell, Nix, and PostgreSQL, deployed to both AWS and bare metal machines. We use a significant amount of open-source technology, and also try and give back where possible (for example, both Rel8 and Fast Downward Haskell bindings).

CircuitHub spans a vast problem space. Challenges include computer vision (OpenCV), machine learning (PyTorch), hard optimization problems (Z3/MiniZinc/OR-Tools), and all the normal engineering challenges of building both web-based customer-facing and internal tooling.

We work on manufacturing execution systems, enterprise resource planning, and robotics. An old video from Haskell Exchange 2019 hints at what we are up to on the robotics side. We have progressed significantly since then!

These roles are remote (any location), in-person, or hybrid, depending on preference.

We have offices in South Deerfield - USA, Cambridge, and London, UK.

Salary depends on the candidate and location, but as guidance in the UK, a likely range is £80k to £125k and in the US $125k to $250k, with additional equity.

CircuitHub has raised $45M from top-tier VCs and has been going for about ten years. CircuitHub is profitable, with tens of millions in revenue. Sma…

What You’ll DoAs a Product Engineer at CircuitHub, you will own entire production software systems end-to-end, from understanding operational problems on the factory floor through designing, building, deploying, and operating the software that solves them. You’ll be responsible for entire systems rather than isolated tickets, owning problems from discovery through deployment and operational impact.

This includes building and maintaining the internal operational stack that seamlessly connects planning, materials, purchasing, personnel, and factory processes, transforming complex manufacturing workflows into highly reliable, usable software. You’ll partner closely with factory operators, engineers, and company leadership to ensure CircuitHub’s factories scale smoothly as demand and Grid capabilities grow.

Example Projects:

Develop production planning tools and inventory/materials-flow systems

Improve factory operator workflows

Integrate new automation equipment

Apply AI and LLMs to automate operational decision making, from purchasing and production planning to machine diagnostics and debugging.

Build the software systems that coordinate thousands of manufacturing decisions across people, robots, inventory, and suppliers in real ti…

What you'll do
Architect the robot operating system. Design the core abstractions: how robots, cameras, tools and jobs are modelled, how work is planned and dispatched, how state is shared and how failures are handled. Decide what belongs in Python and what needs Rust.

Bring in new vision. Integrate novel computer vision algorithms into the control loop, from finding and centring parts to checking every pick and placement, and make them fast and reliable enough for production.

Build agentic robotics. Put large models to work in the robots themselves: programming a new part from its datasheet, judging a pick from a camera image, diagnosing a fault and recovering from it, with evals that prove it works before it runs alone.

Move a fleet. Route dozens of movers at once without collisions or deadlocks, and coordinate gantries, printers and ovens around them.

Bridge to real time. Design clean interfaces between high-level planning and the real-time controllers driving the motors.

Make it observable. Simulation, tracing and replay, so every change is proven before it reaches the factory and every failure can be explained.
