What We're Looking For

Proven ability to lead complex technical projects—owning design decisions, balancing tradeoffs, and guiding implementation across multiple contributors.
You proactively coach and support teammates, foster growth through mentorship, and contribute to a culture of feedback and continuous improvement.
You navigate ambiguity with confidence—able to clarify priorities, align stakeholders, and drive toward meaningful outcomes even when goals shift.
