• Own and evolve the GraphQL API layer serving our most critical customer-facing surfaces, including search, discovery, and checkout.
• Design schemas and query patterns that balance flexibility for consumers with performance and reliability at scale.
• Establish and enforce API Platform standards: schema governance, deprecation policies, federation patterns, and query complexity controls.
• Identify and resolve performance bottlenecks — N+1 patterns, over-fetching, slow resolvers — in production systems under real traffic.
• Partner with product engineering teams as an internal platform owner: unblock them, onboard them, and raise the quality bar across the org.

• Mentor engineers across the org on GraphQL best practices.

What you'll need

• 5+ years of backend software engineering experience, with at least 2 years focused on GraphQL in a production environment.

• Proven track record operating GraphQL at scale — high-throughput, customer-facing APIs where reliability and latency directly affect user experience.
• Strong grasp of distributed systems: how to design services that are observable, resilient, and easy to reason about under load.
• Fluency in at least one of: Java, Go, or Node.js.
• Ability to prioritize and manage stakeholders; known for good communication and collaboration skills.
