Senior Scala Software Engineer

3-5+ (BS) or 1-2+ (MS) years of professional experience building maintainable, well-documented APIs and software

You have a strong grasp of functional programming and type-driven algebraic design (immutability, pure functions, type classes, functional core/ imperative shell) and a track record of building correct, maintainable, well documented software.

You reach for property-based tests and simulation to convince yourself something is right, not just examples.

We will be building foundational pieces from the group up, with rigorous testing.
