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.\nRaised $5M+ in funding from Tier-1 VCs. We work in our SoHo, New York office.\nCulture\nWe hire a small number of extremely talented people and give them as much ownership and autonomy as possible\n\nWe are truth-seeking. Transparent, direct discourse is encouraged. We challenge existing beliefs in pursuit of always getting better\n\nWe work hard and are unapologetic about the level of effort required to build a generational company\n\nWhat You’ll Do\nDefine and build product end-to-end. Deeply understand user needs to iterate on, deploy, and scale software, with extreme ownership\n\nOperate at the frontier. We tackle ambiguous, unsolved problems in AI search that require running experiments to uncover novel insights\n\nDesign and build large-scale systems, data models, and infrastructure\n\nYou’ll Excel in This Role If You\nCan quickly and effectively decompose large, ambiguous problems and systems\n\nHave built real products before and are comfortable owning large technical surfaces\n\nHave strong fundamentals in system design and databases, with good judgment around when to move fast versus build for scale\n\nProcess\n1. Hiring Manager Screen\n2. Technical Interview\n3.
