We're hiring an AI engineer to own the AI systems at the heart of the product. You'll work directly with the founders and own the full loop: data, training, evaluations, and shipping into production.
Compensation
Early-stage compensation: a meaningful equity stake plus salary. Specifics depend on experience and location—we're happy to talk through the details early in the process.
Responsibilities
- Build and own the ML stack—data pipelines, infrastructure, agent optimization, evaluations, tuning
- Ship AI features into production constantly and iterate against real usage
- Improve the evaluation harnesses that tell us whether the product is actually getting better
- Track the research frontier and apply it pragmatically—novelty only where it wins
