About UsWe're a stealth-mode startup backed by Team8 and founded by AI industry leaders. We are building the full-lifecycle trust platform for AI agents — delivering world-class evaluation, guardrails, synthetic data, and continuous optimization. We're at the forefront of a new engineering discipline, and we're building an exceptional team to match.About the RoleWe're looking for a senior backend engineer who thrives on hard, high-leverage problems and owns them end-to-end. Our platform is cloud-native and moving fast, and the challenges we'll point you at are varied — from making our products run in the world's most demanding enterprise environments, to architecting new backend systems, to whatever the next big unlock turns out to be. You're versatile, deeply technical, and equally comfortable going wide across the stack or deep into a gnarly problem. Wherever we send you, you make it run right — and build it so it keeps running. This is work that directly unlocks our biggest opportunities.In This Role You'llTake cloud-native products (like our vibe-training engine) and make them run anywhere — on-prem, air-gapped, and locked-down enterprise environmentsArchitect backend services and deployment topologies that work seamlessly across GCP, AWS, and on-premDesign clean, maintainable systems — strong abstractions, reusable components, code other engineers love to build onOwn the infra stack end-to-end: Kubernetes, Terraform/IaC, networking, storage, and databasesBe the team's tooling obsessive — reach for (or build) the right tool that makes everyone fasterWork hand-in-hand with AI researchers, frontend, and infra engineers to bring new capabilities to life
