Hi, I'm Erik, CTO at Circonomit. We build the decision platform industrial companies use to plan their production. The toughest challenges we're facing:
I need someone to own the engine our models run on: decide how it gets built, build it, keep it running.
Our models decide what gets produced when, on which machine, and at what stock level. The engine sits between the mathematics that makes the answer correct and the product that has to make it usable by people who are not mathematicians.
We came out of RWTH research, raised €2.8M with Vorwerk Ventures, and have customers running on our models today. Small team, Cologne office.
Requirements
You should enjoy turning ambiguous customer problems into models that hold up, rather than waiting for a specification. Priorities change as we learn from customers, and we make scope and trade-offs explicit together.
Benefits Ownership. The engine every customer model runs on: modeling language, compiler, solver integration * Architectural influence. You'll own how modeling and solving evolve here, and make those trade-offs directly with the team * Leverage. You do not build one model for one customer. You build what every model here is built with * Real-world impact. Customers plan their production on our models today * Direct collaboration. Small team, no org chart. We work directly together. Weekly feedback, both ways * Compensation. Competitive salary plus a VSOP package reflecting your contribution and development in the role * Hybrid work. We work from our Cologne office, with one to two home-office days per week. You don't need to live in Cologne, but you do need to be able to work from the office on the remaining days * Your setup and everyday extras.* Hardware of your choice · AI tooling budget · sports membership · Deutschland-Ticket
Process: A 20-minute call, a technical conversation with me and one of our engineers, a three-hour challenge with a 45-minute walkthrough, then a conversation with the team. Two to three weeks overall, with feedback within days.
