About the role
We are looking for a Senior Member of Technical Staff with 5-10 years of experience to help build the primitives for the next 1B agents. This person will be a fast-rising, backend-focused engineer who can lead projects end-to-end. Brainbase has a pipeline of 150+ enterprise accounts and is limited by headcount, so we need a senior builder who can lead engineering as the company scales, and who could grow into a CTO-level leader.
What will you be doing?
- Designing and building core agent primitives (sandboxes, LLM gateway/router, evals, memory, observability) that run as sovereign deployments on bare metal
- Building backend systems at scale for governments, banks and Fortune 500 companies, on deals worth $500K-$1.5M in annual contract value (ACV)
- Owning projects end-to-end, from architecture decisions through production, with full autonomy
- Acting as an engineering lead: setting technical direction, mentoring engineers and helping grow the team
- Working with customers to unblock deployments across a fast-growing enterprise pipeline
