Senior AI Product Engineer

Hybrid – 3x a week onsite in the San Francisco Bay Area

Salary: Up to $250,000 + equity

What Exceptional Looks Like

We’re seeking a builder who has gone beyond experimentation – someone who has successfully taken AI-driven products from concept through production and scale. This individual brings a strong product mindset, approaches problems from the customer’s perspective, and takes full ownership across the stack.

They understand that shipping agentic systems isn’t just about prompts – it’s about disciplined evaluation, iteration, and continuous improvement. They leverage AI tools as accelerators of their own thinking, not substitutes for it.

Equally important, they elevate the team around them: collaborative, intellectually honest, and motivated by collective success as much as individual output.

What Doesn’t Fit

This role is not for someone who relies on AI without understanding it – or who cannot clearly articulate the reasoning behind their technical decisions.

Candidates who have only experimented with models in isolation, without delivering production-grade applications, will not find success here.

Required Experience

• Demonstrated success building and deploying production-grade agentic AI systems in customer-facing environments (not research or prototyping)
• Deep expertise across the agent lifecycle: prompting, evaluation, debugging, iteration, and scaling performance
• Strong foundation in software engineering (backend or full-stack), with a deliberate transition into AI engineering
• Clear ownership mindset – able to articulate what was built, why decisions were made, and how trade-offs were evaluated
• Proficiency in Python or TypeScript
• Experience designing and running evaluation frameworks to measure and improve real-world system performance

Preferred Experience

• Retrieval-Augmented Generation (RAG)
• Experience with agent frameworks or orchestration platforms (e.g., LangChain, AWS Bedrock, or similar ecosystems)

Leveling

• Senior AI Product Engineer: ~4-6 years experience
• Senior AI Product Engineer II: ~6-8 years experience

Note: Experience in high-growth or startup environments is highly valued. Speed, adaptability, and bias for action are critical to success in this role.

Signals of Success (What We Look For)

• Proven track record of taking AI-driven solutions from idea to production, with the ability to clearly walk through the full journey
• Ownership of the evaluation loop – not just building, but rigorously testing, diagnosing, and improving systems over time
• Experience embedding AI into real-world applications, navigating scale, reliability, and user impact
• Thoughtful decision-making – candidates can clearly explain what worked, what didn’t, and why
• Background as a strong engineer who has intentionally evolved into AI, rather than superficially layering AI onto their skillset
