About the job
Location: New York City
At Spur, we create groundbreaking technology designed to redefine quality assurance: autonomous browser agents that think, explore, validate, and self-heal like actual users. We aren’t just another testing tool; we are revolutionizing the way digital teams deliver with confidence.
The market response has been resounding. Leading brands such as Alo Yoga, Living Spaces, HelloFresh, Nextdoor, and Abercrombie & Fitch are actively engaging with us. Demand is skyrocketing, sales cycles are swift, and our product delivers — teams can go live in days, not months.
Our elite team comprises builders from DeepMind, Figma, and former founders who are producing at a pace that larger companies cannot match.
Our Mission: We aim to empower our customers to deliver exceptional digital experiences.
