- Work across the stack to connect frontend experiences with APIs, backend services, and data
- Write clean, maintainable code with strong unit, integration, and end-to-end testing
- Contribute to CI/CD improvements and engineering best practices
- Participate in a reasonable on-call rotation supporting the SaaS platform
Ideal candidate will have:
