  • Expert in (or React), TypeScript, CSS, and component-driven architecture, with experience evolving and governing design systems.
  • Product and outcome-focused: you care about metrics and business impact, not just code.
  • Startup mindset: comfortable with autonomy, ambiguity, and rapid iteration.
  • Leadership experience: mentoring engineers, influencing architecture, and guiding technical standards.
  • Bonus: experience with growth experimentation frameworks, A/B testing, , or AWS.

The team you'll join
A high-autonomy, mission-led team where initiative, learning, and ownership are prized. Collaboration and mentorship are core, and speed is balanced with thoughtfulness - all within a flexible, supportive environment that values results and wellbeing.
