Working directly with partners, you will prototype and ship production LLM tools that redefine how venture capital operates from the ground up.

Location San Francisco, USA

Why this role is remarkable

• Direct access to world-class investors and stakeholders like Reid Hoffman, with feedback loops measured in hours rather than quarters as your users are in the room.


• High-leverage opportunity to define the firm’s technical roadmap and build the AI infrastructure that identifies the next generation of tech giants like Discord or Canva.


• True founding engineer ownership where you skip the ticket queue and PMs to decide exactly what to build and how to build it for maximum impact.

What You Will Do

• Build and deploy custom agent-based workflows that automate complex research, sourcing, and diligence processes across the firm’s portfolio and pipeline.


• Design production systems that integrate LLMs, retrieval pipelines, and structured data into tools that partners rely on for live deal evaluations.


• Sit in on deal meetings to identify workflow bottlenecks and prototype AI-driven fixes within days to enhance the investment team’s decision-making power.

The ideal candidate

• Experienced engineer with 2-5 years of experience who has successfully shipped multi-step LLM workflows or AI agents in a high-stakes production environment.


• Strong full-stack developer capable of owning the entire lifecycle from frontend and backend to data pipelines and deployment without the need for handoffs.


• Product-minded individual with pre-founder energy who thrives in ambiguity and knows when to ship quickly versus building for long-term technical durability.
