NOTE ON ELIGIBILITY : this role is for industry candidates already working in software engineering for the past 1+ years. New grads and current students should NOT apply to this role (instead, visit pplx.ai/newgrads ). About the role In 2026, we launched Computer, the defining product for the new era of agentic AI. Millions of people now use Perplexity to transform knowledge into action, through Search, Comet, and Computer. Product Engineering owns those experiences end to end, from the interface a user touches to the search and model calls behind it, on top of roughly 200M queries a day and a 200B+ URL index. This is a full stack role in the truest sense. There are no frontend or backend lanes here, and no one waits for a ticket before starting. It suits people who love to build and want the room to do it. What you have shipped and how quickly you learn tell us far more than years on a resume or where you went to school. What you will do Own a user-facing surface end to end, from the interaction, design, and frontend through the application logic, APIs, data models, and the search or model calls behind them. Ship to production continuously. New engineers typically have code in front of users in their first week. Build with AI as a primary tool, not a novelty. We expect you to use agents and coding models aggressively to move faster, and to have sound judgment about when their output is wrong. Turn ambiguous product ideas into working prototypes, then use real usage data and evals to decide what survives. Raise the quality bar on reliability, latency, and craft for the surfaces you own. Work directly with designers, PMs, and research engineers, without unnecessary process in between. What we look for 1+ years of professional software engineering experience, or a track record of strong internships where you shipped production code at scale. Strong in at least one backend language, such as Python or Go, with real experience across services, APIs, and relational data m
