    • Develop internal tools and integrate with external APIs

    • Contribute to the expansion, testing, and release of products that impact thousands of customers

Key Requirements:

    • Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience)

    • Working knowledge of React, Next.js, and TypeScript, with a willingness to contribute across the stack

    • Proven ability to work independently, with strong communication and interpersonal skills

We believe:
 
Diversity is a competitive advantage. We celebrate our differences, and are better when we have a variety of experiences, viewpoints, and backgrounds.
 
Compassion is a strength. We care about our customers and look to build long-term relationships with them.
