  • Actively find opportunities that can impact our business, reduce technical debt, or help improve your team’s output and quality.
  • Multiply the output of the frontend team through your leadership, development contributions, and process improvements.


  • You have a history of demonstrating deep empathy for customers in your pursuit of delivering business impact.
