Senior Software Engineer, Data

We are building the world's decision infrastructure: the strategic twin of every industrial organization for complex combinatorial problems. We unlocked what wasn't possible before: mapping reality with its levers and constraints into a computer, then running n-dimensional optimization on critical value-chain decisions. We help Europe stay strong and the German Mittelstand make good decisions between market shifts, orders, machines and people.

Founded by Dana (CEO) and Erik (CTO) from RWTH research, backed by a €2.8M round led by Vorwerk Ventures, with customers live on our optimization models.

We move fast. We care. No patience for problems left unsolved.

Hi, I'm Erik, CTO of Circonomit. This ad is specific on purpose: you should be able to tell from it whether this is your job.

We build decision infrastructure for industrial companies: our customers model their production — capacities, costs, constraints — and we compute the answer to "what should we do?" before the decision is made.

We talk as equals. We communicate proactively and flag it early when something isn't working out. Saying no is part of the job.

We like this work, and you'll notice. The energy of a small team that cares is what people remember about being here. We review each other's code, and we like being together in the Cologne office, because the fastest conversations still happen in a room.
