Software Engineer

• We hire a small number of extremely talented people and give them as much ownership and autonomy as possible
• We are truth-seeking. Transparent, direct discourse is encouraged. 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. We tackle ambiguous, unsolved problems in AI search that require running experiments to uncover novel insights
• Design and build large-scale systems, data models, and infrastructure

• Can quickly and effectively decompose large, ambiguous problems and systems
• Have built real products before and are comfortable owning large technical surfaces
• Have strong fundamentals in system design and databases, with good judgment around when to move fast versus build for scale

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.
