The Position

What You'll Do

  • Deliver incredible products. We’re a product-first company, and we aren’t satisfied until we’ve built a product so clearly superior that customers have no reason to consider anything else.
  • Be a strong technical contributor. As an individual contributor, you’ll write testable, maintainable, scalable code and deploy it frequently. You’ll review the code of other developers, and be open to feedback about your own.
  • Prioritize delivery. Our team ships code multiple times daily, and you’ll help us deliver small continuous improvements with each iteration, if not more frequently.
  • Communicate well. You'll explain your work clearly to team members, and seek feedback to build a codebase we all enjoy contributing to. You’ll keep engineering leadership apprised of important developments on your team, and areas needing attention when appropriate.
  • Be a good teammate. You'll be helpful, open-minded, respectful, and collaborative. You'll support your teammates and challenge them to do their best work.
  • Learn. Regardless of your level of experience or seniority, you'll work to improve your skills and learn more about our customers and their needs.
