Software Engineer III, Copilot Models Inference

About GitHub GitHub is the world’s leading platform for agentic software development — powered by Copilot to build, scale, and deliver secure software. Over 180 million developers, including more than 90% of the Fortune 100 companies, use GitHub to collaborate, and more than 77,000 organisations have adopted GitHub Copilot. Locations In this role you can work from Remote, United States Overview As a software engineer at GitHub, you will enhance the collaboration experience at GitHub by working closely with a community of engineers and designers with a distributed, diverse and passionate team delivering the services that millions of developers depend on. In this role you will design, prototype, implement, ship and support highly performant and inspiring user experiences with your team.   The GitHub Copilot Models Inference team builds and operates the backend services and APIs that connect Copilot experiences to AI model providers. These systems make models available safely and reliably at global scale while managing the production realities of provider integrations, request routing, service health, latency, capacity, and changing model availability.   As a Software Engineer III, you will deliver production features end to end and help operate the services you change. You will participate in design and code reviews, build tests and operational safeguards, prepare changes for rollout, and use production signals to improve reliability and performance. Clear communication matters on this distributed team. You will work with engineers and partners across Models Lifecycle, product, safety, infrastructure, and external model providers through a mix of live conversations and thoughtful written updates. This is a hands-on individual contributor role with opportunities to grow ownership through increasingly independent delivery. Responsibilities ● Design, implement, test, deploy, and maintain backend services and APIs that connect GitHub Copilot experiences to model providers. ● Own scoped features end to end, from technical design and implementation through operational readiness, safe rollout, measurement, and follow-up. ● Integrate new models and provider capabilities while accounting for availability, compatibility, capacity, failure modes, and safe fallback behavior. ● Improve service latency, throughput, capacity efficiency, and high-availability behavior using measurable production outcomes. ● Add and maintain automated tests, dashboards, alerts, runbooks, and diagnostics that make service and model health understandable and actionable ● Keep teammates and partners informed through clear discussions, written updates, and documentation, especially when decisions, risks, or incidents affect others. ● Participate in code reviews and design discussions, incorporating feedback and helping teammates ship maintainable changes. ● Participate in on-call and first-responder rotations, investigate incidents, communicate impact, restore service, and complete appropriate repair and automation work. ● Use progressive delivery practices and production evidence to reduce risk when launching models, changing routing behavior, or updating provider integrations. ● Collaborate with Models Lifecycle, product, safety, infrastructure, and provider partners to deliver model availability and operational improvements across team boundaries.
