Founding Engineer Infra/Backend - Spur

As our founding infra/backend engineer, you’ll architect the backbone of Spur’s core platform—define, build, and scale mission-critical infra powering our web agents.

We own our entire stack end-to-end—you’ll orchestrate fleets of browsers and web agents in the cloud and optimize them at massive scale. You’ll work directly with the founders, solving frontier infra problems with real customer impact, and set the gold standard across our stack, from low-level infra to the UX delivered by our agents.
