About CircuitHub

CircuitHub 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.

What you'll do

• CircuitHub builds circuit boards on demand, every order different. Each day thousands of decisions are made: which orders run on which machines, which parts to buy and when, what to promise a customer and what to charge. You'll build the models behind those decisions.
• Plan the factory.
• Schedule orders, panels and machines across our factories for throughput and on-time delivery, and know days ahead when we will run out of work or capacity.
• Model the Grid.
• The Grid is our factory-scale robot: dozens of movers, gantries, printers and ovens. Model how work flows through it, find the bottlenecks, and tell us what the next machine or change is worth.
• Price and promise.
• Estimate what an order really costs in labour, machine time and parts, and help set prices and lead times that win work and make money.
• Buy smarter.
• Decide what parts and consumables to stock, when to order them, and how much risk of a shortage to accept.
• Put it into production.
• Your models don't live in a spreadsheet: they run every day, feed the planning and quoting systems, and get checked against what actually happened.

What we look for

• A quantitative background in operations research, applied maths, statistics, quantitative finance, economics or a similar field, and a record of models that changed real decisions.
• Optimisation: linear and integer programming, constraint programming, or heuristics, and judgement about when a simple rule beats a solver.
• Simulation and forecasting: building a model of a messy system, calibrating it to data and saying how far to trust it.
• Strong Python and SQL. You write code other people can run and rely on.
• You use coding agents to move faster and take full ownership of what they produce.
• Curiosity about how things are physically made. You'll spend time in our factories in the US and UK.
• Manufacturing experience is welcome but not required. If you have priced risk, optimised a portfolio or forecast demand, the problems here will feel familiar.
• Stack
• Modelling: Python, OR-Tools, simulation
• Data: PostgreSQL, Snowflake, dbt, Dagster
• Agents: Claude Code and Codex throughout
• Location
• Remote anywhere, or from our offices in London or Cambridge (UK) if you prefer, with regular visits to our factories in the UK and US.
• Pay
• UK £80k–£125k · US $125k–$250k, depending on experience, plus equity.
