[Hiring] Software Engineer, Operations Research @CircuitHub

Role Description

CircuitHub builds circuit boards on demand, every order different. Each day thousands of decisions are made:

• 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.

Qualifications

• 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.

Requirements

• 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.
