🧠 The role

Join as a founding Data Scientist and build our learning-augmented optimization stack for real-world planning & routing.

🔍 What you’ll do

Design & ship optimization services for planning (heuristics + learning-based). 🚚
Deliver measurable wins on cost, feasibility, SLA adherence, and latency. 😮‍💨
Add ML where it matters: forecasts, service times, policy/value learning. 📈
Build diagnostics so operators trust outputs. 📦
Partner with customers to turn rules into deployable models. 🤝

Must-have skills

5+ years building & shipping optimization/ML systems (or PhD + 2 yrs).
Track record of taking ideas from research to production.
Depth in at least one: RL, (very) large-scale optimization, or applied ML (focused on graphs).
Strong systems experience (production code, pipelines, orchestration, monitoring).
Clear communication; fluent English.
Nice to have: routing/planning, forecasting, or graph learning.
German (B2+) is a plus. 🇩🇪

👩‍💻 How we work
