About this role

**About the role** We build materials-science and engineering tasks that test how well an AI model does real expert work. You write a realistic task — a prompt, a data room, and a way to grade it — run it against the model, and tighten it until the model can no longer reason through it cleanly. **What you'll do** - Author domain-authentic tasks drawn from work you've actually done. - Build the data room and grading criteria that make the task objectively scorable. - Run the task against the model, analyse where it succeeds or fails, and iterate until it genuinely discriminates. - Work with the project lead and other domain experts to settle what "good" looks like in your domain. **Who we're looking for** - Senior expertise in **materials science** — metals, ceramics, composites, characterization, additive manufacturing — or in **electrical engineering** (analog, RF, power) or **mechanical engineering** (design, CFD and fluids, heat transfer, pressure vessels, NDE, CAE). - Comfortable navigating ambiguity — much of the work is still being defined, and shaping it is part of the role. - Able to explain not just the right answer, but why a wrong answer is wrong. **Support** Daily onboarding sessions and multiple office hours every day.

Confidence describes how well the ownership is evidenced. It is not a rating of how the platform treats the people who work for it, which no public source covers reliably.
