<h2>About CircuitHub</h2><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">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.</p><p style="min-height:1.5em">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.</p><h2>What you'll do</h2><p style="min-height:1.5em">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.</p><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Plan the factory.</strong> 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.</p></li><li><p style="min-height:1.5em"><strong>Model the Grid.</strong> 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.</p></li><li><p style="min-height:1.5em"><strong>Price and promise.</strong> 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.</p></li><li><p style="min-height:1.5em"><strong>Buy smarter.</strong> Decide what parts and consumables to stock, when to order them, and how much risk of a shortage to accept.</p></li><li><p style="min-height:1.5em"><strong>Put it into production.</strong> 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.</p></li></ul><h2>What we look for</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em">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.</p></li><li><p style="min-height:1.5em">Optimisation: linear and integer programming, constraint programming, or heuristics, and judgement about when a simple rule beats a solver.</p></li><li><p style="min-height:1.5em">Simulation and forecasting: building a model of a messy system, calibrating it to data and saying how far to trust it.</p></li><li><p style="min-height:1.5em">Strong Python and SQL. You write code other people can run and rely on.</p></li><li><p style="min-height:1.5em">You use coding agents to move faster and take full ownership of what they produce.</p></li><li><p style="min-height:1.5em">Curiosity about how things are physically made. You'll spend time in our factories in the US and UK.</p></li></ul><p style="min-height:1.5em">Manufacturing experience is welcome but not required. If you have priced risk, optimised a portfolio or forecast demand, the problems here will feel familiar.</p><h2>Stack</h2><ul style="min-height:1.5em"><li><p style="min-height:1.5em"><strong>Modelling:</strong> Python, OR-Tools, simulation</p></li><li><p style="min-height:1.5em"><strong>Data:</strong> PostgreSQL, Snowflake, dbt, Dagster</p></li><li><p style="min-height:1.5em"><strong>Agents:</strong> Claude Code and Codex throughout</p></li></ul><h2>Location</h2><p style="min-height:1.5em">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.</p><h2>Pay</h2><p style="min-height:1.5em">UK £80k–£125k · US $125k–$250k, depending on experience, plus equity.</p><hr><p>Compensation: £80K – £125K • Offers Equity • Multiple Ranges</p><ul><li>UK • £80K – £125K • Offers Equity</li><li>US • $125K – $250K • Offers Equity</li></ul><p>Find more <a href="https://www.arbeitnow.com/english-speaking-jobs">English Speaking Jobs in Germany</a> on Arbeitnow</a>
