The role
This company is building an AI operating system to transform acquired B2B SaaS businesses. They ingest vast amounts of operational data, encode best practices, and deploy autonomous agents to automate critical workflows across a growing portfolio. The founding team brings deep experience from large-scale data platforms and frontier AI, backed by leading investors.
This Staff Software Engineer role is a pure technical leadership seat. You will own the most challenging end-to-end problems, architecting a platform that integrates deeply into diverse business data and scales across multiple acquired companies. This is not a management track; you will work directly with leadership on technical direction, anchor critical workstreams, and elevate the team's technical bar through hands-on contribution and mentorship. We need a force multiplier for a small, fast-moving group, not someone focused on 1:1s.
