An early-stage agentic data platform building comprehensive intelligence on people.

Staff Backend Engineer

San FranciscoOn-site$250K - $300K8 - 12 years
Traditional data pipelines choke on the nuance of human identity, leaving critical context scattered across disconnected systems. As our first dedicated backend architect, you will engineer the foundational infrastructure that synthesizes vast, fragmented inputs into coherent, agentic intelligence. You will own the server-side architecture from the metal upward, designing resilient systems across AWS and GCP that transform raw data into actionable knowledge. This is a greenfield opportunity to define the technical backbone of a small, focused team based in San Francisco.

What they're looking for

  • 8 to 12 years of backend engineering experience, with deep expertise in distributed systems
  • Proven ability to design and scale data-intensive server infrastructure on AWS and GCP
  • Comfort operating as a foundational technical hire within a small, early-stage environment
  • Willingness to work on-site in San Francisco
  • Strong architectural instinct for modeling complex, interconnected data
