Who We're Looking For

Can talk fluently about retrieval, memory, agent frameworks, context engineering, eval pipelines and anything else at the cutting edge

Combine strong software engineering fundamentals with deep awareness of what's happening at the frontier of LLMs and agentic systems

Thrive in startup environments where the problem is ambiguous and the team is small

Have 2-8 years of experience, ideally with experience at at least one high-growth company

$200,000 – $400,000+ base salary depending on experience and role. Many positions include meaningful equity at pre-seed through Series B stage companies.

The Interview Process (Typical)

Screening conversation looking for communication skills, cultural fit, genuine curiosity about AI
