  • Write clean, tested, well-documented code that your teammates enjoy working with

  • Integrate with REST APIs and collaborate with backend engineers on data flows

  • Refactor and improve existing codebases, reducing technical debt where it matters

  • Write unit and E2E tests to keep our platform stable and reliable

  • Familiarity with performance monitoring and observability tools.

  • Experience with internationalization/localization in multi-language applications

  • Understanding of donation/payment form integrations

  • Bonus skill: a surprisingly solid taste in bad music for the perfect sprint song
