Note: The job is a remote job and is open to candidates in USA. GitHub is a leading AI-powered developer platform that supports software development and collaboration through GitHub Copilot. The Staff Software Engineer will build and operate the Sessions and Tasks APIs powering Copilot agent experiences, while leading API design, distributed systems scalability, security and authorization, staged rollouts, and cross-team platform initiatives.
Responsibilities
- Design, build, and operate the Sessions and Tasks APIs (Go, Azure CosmosDB, Azure Blob Storage, Event Hubs) that back every Copilot agent surface: Copilot Coding Agent, Copilot CLI, VS Code Chat, JetBrains Chat, and Copilot Chat on github.com
- Own and evolve the agent registry and remote steering model, including the policies that decide who can create, edit, or remotely control a session (org/enterprise settings, MDM host managed settings, SSO organization requirements, and staff/internal bypass rules)
- Drive spec first API design: propose changes to the OpenAPI description, regenerate strict server bindings, and coordinate breaking or additive schema changes across client and platform teams (copilot-agent-runtime, sweagentd, copilot-api, the github/github monolith, and github-ui)
- Write architecture decision records and design proposals for new platform capabilities (for example: the Agent Host Protocol for user managed and sandboxed environments, token sealing and minting for secure relay, and unified steering across synchronous and asynchronous agents)
- Ship safely at scale using staged, feature flag gated rollouts (observe-then-enforce patterns) across dotcom, GHES, and Proxima tenants
- Provide technical leadership and mentorship through design review, pairing, and PR review, raising the bar on idiomatic Go, dependency injected and interface first design, and table driven testing
- Partner with adjacent teams on distributed systems concerns: CosmosDB data modeling and query performance, Kubernetes/Kustomize deployment configuration, Terraform provisioned Azure infrastructure, and service health/on call practices
- Represent Mission Control in cross-org design discussions (security/IAM, identity and step up authentication, enterprise policy) and help drive open questions to a shipped, well tested outcome
