Spur builds validation infrastructure for the future of QA: autonomous browser and app agents that think, explore, validate, and self-heal like real users. We’re not another testing tool — we’re reimagining how digital teams ship with confidence.
The market has responded loudly. Top enterprises (Docusign, Alo Yoga, Living Spaces, HelloFresh, Nextdoor, Abercrombie & Fitch, and more) are actively pulling us in. Inbound demand is exploding. Sales cycles are fast. And the product actually delivers - teams go live in days with us.
We’re a small, elite team of builders from DeepMind, Figma, ex-founders and customers - shipping at a pace that big companies can’t touch.
Our Mission: We want to help our customers move at the pace of generation with strong validation infrastructure
As our Founding Infra/Backend Engineer, you’ll architect the backbone of Spur’s core platform-define, build, and scale mission-critical infrastructure powering our agents. You will orchestrate fleets of browsers, emulators, simulators, and agents in the cloud and optimize them at massive scale. You’ll work directly with the founders, solve frontier infrastructure problems with real customer impact, and set the gold standard across our stack.
