Staff/Principal Product Engineer

About the role

Uniti AI is a Series A startup building advanced AI sales and support agents for the real estate industry. As a Staff/Principal Product Engineer, you will own product bets from research and discovery through to building proofs of concept and MVPs. This role focuses on deep systems and AI work, requiring you to define product direction and technical strategy in collaboration with leadership.

Responsibilities

• Own the full arc of a product bet: research and discovery, customer and data analysis, scoping, then building the proof of concept or MVP yourself.
• Work directly with customers and the go-to-market team to understand where our agents fall short and what would move the needle.
• Design and build agentic workflows, agent harness improvements, tool integrations, and the backend systems behind them.
• Make the call on what to build, what to cut, and what to kill, backed by evidence rather than opinion.
• Hand off proven prototypes to the platform engineering team, or productionize them yourself when that's the faster path.
• Set the bar for how we evaluate agent quality: evals, instrumentation, and the metrics that tell us whether something actually works.
• Collaborate directly with the Head of Product and the founders on product direction and technical strategy.
• Debug and solve problems across the stack, no "not my job" mentality.
