Lead development of user-facing features with clean, responsive frontend code
Design and implement RESTful and GraphQL APIs that connect media and commerce services
Collaborate closely with product, design, and QA to ship well-scoped, high-impact releases

Support the architecture and evolution of our headless commerce infrastructure
Participate in sprint planning, technical design reviews, and postmortems

Comfortable building and consuming APIs in production environments
Experience collaborating in agile teams with clear ownership over a domain
