Is This Role For You?
- You've shipped production AI agents or agentic workflows in Python at scale (LangChain, LlamaIndex, CrewAI)
- You thrive in ambiguous, fast-moving environments and can consult with non-technical stakeholders
- You want to directly influence business strategy, not just execute tasks handed down
- You're energized by the intersection of AI infrastructure and business impact in enterprise/VC contexts
- You need remote flexibility-this is on-site San Francisco only
- You prefer deep specialization in one domain over wearing multiple hats across deal sourcing, portfolio, and data teams
- You've never shipped production LLM or agentic systems in a business-critical setting
