About the Role

We're looking for a Senior AI Product Engineer to own the continuous improvement of our customer-facing AI products, making them more accurate, reliable, cost-efficient, and genuinely useful to the people who rely on them every day. This isn't a prompt-writing job, it's about building the structured loop of evaluation, experimentation,



and analytics that turns AI from a feature into a measurable product advantage. You'll work at the intersection of Product, Growth, and Engineering, with real influence over how AI behavior gets measured, improved, and shipped.

What You’ll Do
- Own the end-to-end quality of our AI-powered product experiences, improving response usefulness, consistency, and reliability in ways users actually notice.
- Build evaluation frameworks and repeatable test sets so we can measure AI quality objectively, not anecdotally.
- Design and run experiments on prompts, context strategies, and model settings, connecting every change to activation, conversion, retention, or satisfaction metrics.
- Monitor and reduce AI-related costs (tokens, latency, model choice, retrieval) without compromising the user experience.
- Translate AI failure patterns, hallucinations, inconsistent outputs, weak reasoning, into clear, prioritized fixes for P
