You will build the platforms, services, and controls that help enterprise customers securely configure, govern, and operate GitHub Copilot at scale. This is a hands-on platform engineering role centered on cross-team integration, workflows, and state management. You will turn customer and business requirements into clear APIs, coherent domain models, enforceable policies, and reliable production services. The work spans questions such as which service owns a configuration change, how that change moves through dependent systems, when it takes effect, and what evidence administrators need to understand the result. You will design reliable behavior across service boundaries: clear ownership of state, explicit workflow transitions, safe retries, handling of partial failures, and compatible API and event contracts. Success means more than choosing an architecture. It means explaining the tradeoffs, implementing the critical paths, agreeing on integration contracts with partner teams, and owning the system in production. Deep production engineering experience is essential. Prior AI or LLM experience is valuable but not required. We welcome engineers who have personally designed, implemented, and operated services that coordinate workflows and state across multiple systems. We value clear reasoning about service contracts, data ownership, failure behavior, and safe evolution.

You will partner with product, design, security, and other Copilot engineering teams to make governance capabilities trustworthy and straightforward to adopt across various client surfaces. We value curiosity, maintainable systems, clear communication, and collaboration. How we build is as important as what we ship. Responsibilities Design, implement, test, ship, and support backend services and APIs for enterprise configuration, policy enforcement, and auditing. Develop clear domain models and API and event contracts, including state ownership, resource lifecycles, authorization boundaries, and compatibility. Implement workflows across dependent services, with explicit state transitions, idempotent operations, and recovery from interrupted or partially completed work. Lead architecture decisions by framing the customer problem, identifying constraints, evaluating alternatives, and making correctness, reliability, cost, and usability tradeoffs explicit. Remain close to implementation through coding, debugging, prototyping, pairing, and code review. Help other engineers build extensible, maintainable software. Partner with teams that own upstream and downstream services to agree on integration contracts, dependency behavior, and ownership. Design versioning, staged rollouts, and migrations that consumers can adopt safely. Own service health through meaningful telemetry, actionable alerts, incident response, and participation in on-call and first-responder rotations. Establish success criteria before launch. Use automated tests, production telemetry, customer feedback, and, where relevant, AI evaluations to identify failures and measure improvement. Build and improve CI/CD pipelines and release practices that support safe, repeatable delivery. Write architecture briefs and proposals that make complex decisions understandable and support alignment across teams. Drive a technical roadmap aligned with product goals, balancing customer capabilities with reliability, security, maintainability, and engineering cost.

Lead technical direction and hands-on development of AI-powered code review agent, mentor senior staff, and collaborate with research teams. | Extensive software engineering experience with multiple languages and production-scale systems, preferably with AI or LLM product experience. | 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 AI writes code faster than teams can review it, and review is now the bottleneck. Getting an agent to review as well as, or better than, a great engineer who knows your codebase is one of the most important unsolved problems in AI-assisted development. Copilot code review is GitHub's answer, and more developers get reviews from it than from any other AI reviewer, increasingly on code that agents wrote. Getting review right is hard to define and harder to measure, and no single number settles whether reviews got better. We think the AI products that win are the ones with the best evals, and we're building the best, offline and online. We run at GitHub scale with an on-call rotation, and we're a fast-growing team competing to build the best AI code reviewer in the world. As a Principal Software Engineer here, you'll be a technical owner of how Copilot code review works, and you'll be working out what this job becomes: we build the tool that's changing how engineers work, and this role leads how our own team adapts. This is a hands-on role: you'll be in the code, solving the hardest technical problems yourself, not just guiding the work. Responsibilities Drive how the review agent works: the context it reasons over, the models it runs, and what it carries across reviews. Bet on where model capability is heading, and work with model labs and research teams to turn it into better reviews. Define what a great AI review is, and hold the product to it with offline evals, online experiments, and production evidence. Own the quality of the end-to-end review experience across VS Code, the GitHub Copilot app, and the GitHub Copilot CLI, and pull requests. Own the reliability of a high-throughput service running at GitHub scale, including the on-call rotation. Mentor senior and staff engineers, collaborate across disciplines, and help steer the team and product, all while staying hands-on: experimenting, shipping code, and building evals. Work at the frontier of how software gets built with agents and evolve workflows that make the whole team faster.

Own complex AI-driven code review product problems end-to-end, build evaluation infrastructure, and maintain high-throughput distributed services. | 3 to 9+ years software engineering experience, proficiency in multiple languages, and experience with production distributed systems. | 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 AI writes code faster than teams can review it, and review is now the bottleneck. Getting an agent to review as well as, or better than, a great engineer who knows your codebase is one of the most important unsolved problems in AI-assisted development. Copilot code review is GitHub's answer, and more developers get reviews from it than from any other AI reviewer, increasingly on code that agents wrote. Getting review right is hard to define and harder to measure, and no single number settles whether reviews got better. We think the AI products that win are the ones with the best evals, and we're building the best, offline and online. We run at GitHub scale with an on-call rotation, and we're a fast-growing team competing to build the best AI code reviewer in the world. As a Staff Software Engineer here, you'll take the problems nobody has answered yet and ship the answer: when a review should stay quiet, or what the agent should learn about a codebase instead of being told. You won't be handed a spec. Other engineers will follow the calls you make, but you lead by building, not by writing the plan. Responsibilities Own product problems that arrive without an answer and ship the answer end to end. Advance how the agent reviews: the context it uses, what it remembers, and how it improves over time. Decide what a good review looks like for a class of code, then build the evals that hold the product to it. Make the quality, latency, and cost tradeoffs that decide how deep a review goes. Improve review quality in aggregate and quantify the gain, including when a change wins overall and loses on some pull requests. Shape the end-to-end review experience across VS Code, the GitHub Copilot app, and the GitHub Copilot CLI, and pull requests. Keep a high-throughput service healthy at GitHub scale, including an on-call rotation. Work at the frontier of how software gets built with agents and evolve workflows that make the whole team faster. Qualifications Required Qualifications 9+ years experience in Software Engineering, Computer Science, or related technical discipline with proven experience maintaining and delivering production software coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, Go, Ruby, Rust, or Python OR Associate’s Degree in Computer Science, Electrical Engineering, Electronics Engineering, Math, Physics, Computer Engineering, Computer Science, or related field AND 8+ years experience in Software Engineering, Computer Science, or related technical discipline with proven experience maintaining and delivering production software coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, Go, Ruby, Rust, or Python. OR Bachelor's Degree in Computer Science or related field AND 7+ years experience in Software Engineering, Computer Science, or related technical discipline with proven experience maintaining and delivering production software coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, Go, Ruby, Rust, or Python. OR Master's Degree in Computer Science, Electrical Engineering, Electronics Engineering, Math, Physics, Computer Engineering, Computer Science, or related field AND 5+ years experience in Software Engineering, Computer Science, or related technical discipline with proven experience maintaining and delivering production software coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, Go, Ruby, Rust, or Python. OR Doctorate in Computer Science, Electrical Engineering, Electronics Engineering, Math, Physics, Computer Engineering, Computer Science, or related field AND 3+ years experience in Software Engineering, Computer Science, or related technical discipline with proven experience maintaining and delivering production software coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, Go, Ruby, Rust, or Python. OR equivalent experience. Preferred Qualifications: Hands-on experience pushing coding agents to their limits, with a view on where they should and shouldn't own engineering work. Experience owning the measurement that makes a model-driven product improvable and catching metrics that move for the wrong reason. Depth in Go, Ruby, TypeScript, or Python, with the operational experience of running a distributed service on call at GitHub scale. Experience shipping an LLM-backed or agentic product, or the eval infrastructure behind one. Compensation Range The base salary range for this job is USD $140,400.00 - USD $372,300.00 /Yr.
