About the job
Own how Mimo, an agentic system for making physical things, reasons and uses tools, and build the evaluations that determine what ships.
What you'll do
- Manage system context, retrieval, and memory as a measured budget.
- Define reliable tool contracts, including results and failure modes.

What they ask for
- Production agent systems experience, including tool use, multi-step loops, streaming, and failure recovery, with demonstrable results.
- Experience designing graded evaluations, regression gates, and human review.
- Context engineering across prompts, retrieval, and memory, with measured costs; tool design with schemas, results, and errors.
- Python, plus either a large production codebase with a strict test baseline or a published benchmark you built.
Nice to have
- Parametric or code-first CAD authoring or 3D geometry fluency.
- Multi-model routing and cost attribution, fine-tuning for tool use, production retrieval systems, published evaluations, or agent-product voice and UX writing.
