## Job Description

## Responsibilities

- Lead complex projects from experimentation through production.
- Engage directly with customers to inform product decisions.
- Mentor engineers, share technical knowledge, and help teammates grow.

- Experience leading complex projects from experimentation through production.
- Experience mentoring engineers.
