Qualifications

Why is This a Great Opportunity:

Join a team building mission-critical software that turns complex technical concepts into tools decision-makers actually rely on.

You'll work across the full stack from backend services to the interfaces that make sophisticated simulations and optimization models usable and across the full lifecycle, from early prototyping through deployment.

We're a small, collaborative group where engineers own real problems end to end.

If you like working close to the research, translating hard technical ideas into clean, maintainable software, and seeing your work go from whiteboard to operational use, this role is built for you.
