Member of Technical Staff

As a Member of Technical Staff, you’ll own meaningful parts of Darwin from initial design through production. You’ll work closely with the founders to turn difficult technical problems into products people use, measure where they succeed or fail, and improve them.

• Have built and shipped production software and taken responsibility for how it performs.
• Bring depth in search, distributed systems, data infrastructure, applied AI, or product engineering.
• Can take an ambiguous problem, make sound technical decisions, and deliver a working solution.
• Care about product details and can explain complex system behavior clearly.
• Are comfortable investigating failures across models, services, and interfaces.
• Work independently, communicate directly, and revise your approach when the evidence changes.
• Have experience with retrieval, ranking, agent evaluations, or agent protocols is valuable. You don’t need experience in every area above; we’re looking for technical depth, judgment, and the ability to build.
