About the role

You'll work across the full lifecycle of AI-driven features-from data ingestion and model orchestration to output structuring and delivery into user-facing product surfaces.
You'll also play a key role in elevating the team: guiding technical decisions, mentoring engineers, and raising the bar for both product thinking and engineering quality.

Own end-to-end delivery of AI product features
Lead the design and implementation of complex features-from initial concept through production-ensuring high quality and strong user impact.
Drive system design for AI-backed experiences
Lead technical direction within a product area
Provide guidance on code quality, system design, and product thinking; help less experienced engineers operate more effectively in an AI-driven environment.

Has 5+ years of experience building and scaling product-facing systems, with a track record of owning complex features or product areas end-to-end

Salary Range: $185,000 to $230,000 USD per year.
This salary range represents the low and high end of the estimated salary range for this position. The actual base salary offered for the role is dependent on several factors. Our base salary is just one component of a comprehensive total rewards package.

Elevate product quality through iteration and evaluation
Mentor and raise the engineering bar
Accelerate team velocity through AI-assisted development
Writes clean, maintainable code (Python preferred) and makes strong architecture and design decisions across a modern web stack
Brings a high bar for product quality, not just system correctness - consistently asks whether what's being built actually serves users well

Drives projects from idea → production with strong ownership, and helps others do the same through mentorship and technical leadership
Thrives in ambiguous, fast-moving environments and can set technical direction, not just execute within it
Experience building or experimenting with LLM-powered features (prompting, evaluation, RAG, etc.)
Experience designing systems that balance latency, cost, and quality
