About The Position

Seed-stage AI security startup is hiring a senior backend/platform engineer to help build the runtime control layer for enterprise AI agents. This is a first key engineering hire role with direct access to the CTO/founding team, high ownership, and a path to help build the engineering team. The company is building infrastructure that helps regulated enterprises safely deploy AI agents by controlling agent access to tools, identities, workflows, and sensitive data.

Requirements

5+ years of backend/platform engineering experience
Strong Go preferred; Java or Rust also relevant
Experience building distributed systems, cloud infrastructure, networking, gateway/proxy systems, identity/auth, or security infrastructure
Hands-on experience with AWS, GCP, Azure, Kubernetes, Docker, APIs, and production operations
Comfortable in an early-stage startup with ambiguity and high ownership
Product-minded, able to take vague problems and turn them into working software

Nice To Haves

Experience at infrastructure, cybersecurity, networking, developer tools, or cloud companies is a strong plus
Not a fit for Frontend-heavy or purely full-stack profiles
Python-only backend experience without Go/Java/Rust systems work
Consumer-only product backgrounds without infrastructure/security/cloud depth
Big-tech-only candidates with no startup or high-ownership environment experience

Responsibilities

Build backend services for agent connections, tool access, execution records, and control workflows
Own production paths where authentication, state, latency, and failure handling matter
Design APIs and data models that make agent activity reliable and understandable at scale
Work on cloud, hybrid, and on-prem deployment patterns
Help shape product and technical direction from an early stage
Set a high engineering bar through design, implementation, code review, and mentorship
