circuithub - Operations Research

• 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. • Modelling: Python, OR-Tools, simulation • Data: PostgreSQL, Snowflake, dbt, Dagster • Agents: Claude Code and Codex throughout • UK, remote, with regular visits to our factories in the UK and US. • £80k–£125k, depending on experience, plus equity.
