- Knowledge of API design and experience with API integration / testing / design / implementation (e.g. GraphQL, REST, etc.).
- Experience with version control.
- Knowledge of CI/CD pipelines and typical integrations.
- Experience with unit testing (Mocha, Jest, Jasmine, etc.).
- Understand the importance of automated testing, and have experience implementing automated tests.
- Knowledge of the most common non-functional requirements (NFRs) including performance, reliability and availability, usability and accessibility, security, maintainability, scalability, observability, portability, and compliance (e.g. GDPR) and an understanding of how to build digital products that meet them.
- Experience with AI-assisted development: comfortable delivering quality code using CLI or editor-based LLM agents; using MCP servers; and maintaining up-to-date documentation.
Nice to have experience:
- Experience with deploying, hosting, securing, monitoring and scaling in the cloud (AWS, Azure or GCP).
