Senior Software Engineer

Our Runtime organization owns the critical tier of GraphOS - the underlying engine central to making GraphOS a highly performant, secure, governed, and reliable self-service GraphQL platform. As a key member of the Router Core team, you’ll be at the heart of this mission, building and maintaining the de-facto standard GraphQL runtime platform, enabling engineering teams to ship faster and deliver richer experiences than ever before.

What You'll Do

• Build, test, and maintain fault-tolerant infrastructure for GraphQL runtime platforms, primarily in idiomatic Rust, ensuring security, performance, and reliability.
• Operate and improve durable, stable public APIs used by the world’s most demanding GraphQL workloads.
• Engage directly with users — whether community members or enterprise customers — to understand their needs, debug issues, and bring insights back to influence the platform’s evolution.
• Design scalable, observable systems that integrate seamlessly into diverse customer infrastructure stacks, leveraging self-initiated research and real-world feedback.
• Collaborate with engineers across teams using supportive communication and constructive code reviews to deliver cohesive solutions.
• Mentor and guide teammates in architecting and writing idiomatic Rust code, while considering the end-to-end impact of changes and ensuring alignment with cross-domain concerns.
• Lead architectural discussions and cross-team initiatives, driving impactful changes as a technical leader or coaching others to step into leadership roles.
• Develop comprehensive technical designs and documentation that address cost efficiency, security, and observability.
• Participate in on-call rotations to ensure the reliability of mission-critical systems.
