- Collaborate with cross-functional teams to understand user requirements, implement and iterate on features used in our product and by the engineering org as a whole.

- Work with front end developers, product management and customers to deliver customer facing features such as public facing APIs and the technology behind Astro’s own infrastructure.

- A track record in building performant, scalable, and reliable backend systems.

- Strong written and verbal communication skills, with a collaborative mindset.

- Experience in developing services with Go, interacting with dependencies and service orchestration on Kubernetes.

- Advanced understanding of distributed systems concepts and NALSD https://sre.google/workbook/non-abstract-design/.

- Experience rationally leveraging AI coding assistants and LLMs (e.g., Claude, Cursor, Gemini) to accelerate development — from prototyping and automated testing to code refactoring and documentation.
