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.
No patience for problems left unsolved.
Your missionHi, 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.
Your mission: scale our data platform for multiple customers and domains.
Customer data arrives in many formats from many sources, ERP exports included; it has to land in our system consistently, stay manageable at millions of records, and be fast to query when models and results are on screen.
The product is a data-heavy web app with a math-heavy backend (Python, TypeScript, Solid.
js, Postgres, on Cloudflare): your center of gravity is data and infrastructure, but you touch the whole stack.
We are looking for a system thinker who wants to shape the architecture, and more than that.
We will not sugarcoat it: short deadlines, real workload, and a platform that grows while customers already run on it.
What you'll ownThe data platform end to end: ingestion, storage, and the query paths that keep millions of records fast on screen.
You design it, you build it, you run it in production.
The platform layer, directly with the CTO: infrastructure, deployments, and the path to productio.
