# Software Engineer - Company: [Petra Labs]() - Location: New York City - Team: Engineering - Employment type: Full Time - Posted: February 21, 2026 ## Job description **About Petra Labs** Petra Labs is building the attribution and experimentation layer for AI search. We believe the future of commerce will be shaped by AI-driven information retrieval, yet most companies lack the infrastructure to understand and capitalize on this emerging growth channel. Petra Labs uses large-scale simulations, agentic analysis, and deeply embedded integrations to turn AI search from a black box into a measurable growth channel teams can rigorously optimize and allocate spend against. Raised $5M+ in funding from Tier-1 VCs. We work in our SoHo, New York office. **Culture** * We hire a small number of extremely talented people and give them as much ownership and autonomy as possible * We are truth-seeking.

We challenge existing beliefs in pursuit of always getting better * We work hard and are unapologetic about the level of effort required to build a generational company **What You’ll Do** * Define and build product end-to-end. Deeply understand user needs to iterate on, deploy, and scale software, with extreme ownership * Operate at the frontier.
