Senior Engineer - Backend & Platform
About this role
What we're looking for:
We're looking for a generalist, high-agency engineer with 5+ years of backend experience building customer-facing products. You should have startup DNA — experience at top-tier startups (Series B or earlier) or as a founder — and a product mindset that ties technical decisions to business impact. We need someone who questions the "why, " drives projects end-to-end without oversight, and thrives in early-stage ambiguity with high ownership and fast iteration.
What you'll do:
Own and ship product features end-to-end — from problem scoping through backend implementation to production
Design and ship LLM agents that reason over large, messy, real-world organizational data, and make them reliable enough to trust
Make key technical decisions across the product and backend — architecture, data modeling, APIs, tooling — and set the engineering quality bar
Operate with full autonomy; in a team this small, your judgment directly shapes the product, the codebase, and the company
Own high-risk, high-impact projects in a fire-and-forget work style with minimal hand-holding
Shape the product direction alongside the founding team; translate customer needs into technical solutions
Work closely with the founding team to support growing client engagements ranging from hundreds to thousands of employees
