About The Position

As a Staff Software Engineer on the Copilot Agents team at GitHub, you will help shape the future of agentic software development. Working at the forefront of AI-powered coding, you’ll partner with engineers, researchers, and designers to deliver experiences that millions of developers rely on every day. The Copilot Agents team builds GitHub’s core platform for agentic development, including the Copilot CLI, SDK, and agent harness; Copilot Cloud Agents and Chat; Copilot Context services such as Memory and Semantic Search; and client experiences across Web, Mobile, and Desktop. In this role, you’ll work across these layers to unlock dramatic improvements in developer and organizational productivity through agentic capabilities spanning the software development lifecycle. You will design, build, and ship performant, reliable, and inspiring agent experiences—from issue-to-PR coding agents and asynchronous task execution to multi-step tool use, sandboxed execution, and integrated reviewer/agent collaboration loops. You’ll work across clients, services, and platforms to deliver cohesive, high-quality developer experiences, while helping expand GitHub’s platform to support the agentic SDLC. We’re looking for creative problem solvers who care deeply about both culture and customers. You bring experience building complex systems—ideally agentic or AI-powered—and a passion for developer tools and platforms. You thrive in ambiguity, work effectively across boundaries, and turn bold ideas into impactful products. We believe how we build matters as much as what we build. Shared purpose, curiosity, quality, and collaboration are what drive great outcomes—and great products reflect the teams behind them.

Nice To Haves

Experience in one or more scripting languages (e.g., Bash, Python, or a similar language), technologies and software platforms (e.g., Ruby, React, Go, JavaScript/TypeScript, MySQL, CosmosDB, Elasticsearch), front-end frameworks (e.g., React.js), and/or telemetry dashboards (e.g., Datadog, Sentry, Azure Data Explorer).
Experience with cloud environments and/or Cloud Native Compute Foundation (CNCF) concepts.
Demonstrated experience with large-scale system architecture and design, particularly in cloud-based environments, with a strong understanding of distributed systems and microservices.
Experience working closely with product management, design, and other engineering teams to drive cross-functional projects and deliver high-quality products.
Hands-on experience building agentic systems – multi-step planning loops, tool use, retrieval-augmented generation, sandboxed code execution, or autonomous task completion – on top of frontier LLMs (e.g., Claude, GPT-4/5-class models).
Experience with evaluation methodologies for non-deterministic AI systems, including offline benchmarks, online A/B experiments, and human-in-the-loop quality measurement.
Familiarity with the GitHub developer platform – repositories, pull requests, Actions, Issues, and the GitHub REST/GraphQL APIs – and a passion for the developer experience.
Awareness of AI safety and security concerns specific to coding agents, including prompt injection, sandbox escape, secret leakage, and supply-chain risk, with a track record of designing mitigations.

Responsibilities

Design, develop, test and ship high-quality technical solutions that scale across multiple GitHub services and become intimately familiar with the systems you build and take pride in writing maintainable code.
Provide technical leadership, mentorship, pairing opportunities, and code reviews to encourage the growth of others; support teams in producing extensible and maintainable code, ensuring integration with downstream dependencies and adherence to quality standards.
Build and use agentic tooling to accelerate your own and your team’s impact.
Own and advocate for the health and quality of the systems that the team builds, including participating in on-call for first responder rotations and live incidents.
Write architecture briefs and proposals and carry out code experiments.
Design and implement APIs to facilitate seamless integration between software components.
Collaborate with cross-functional teams and partner with stakeholders and lead discussions for technical solutions, including design and cost considerations.
Maintain executional and operational excellence within and potentially across teams/organizations.
Drive and support the technical roadmap for Copilot Agents that aligns with product goals, ensuring engineering efforts are strategically prioritized and incorporating the adoption of new model capabilities, agent frameworks, and methodologies as the AI landscape evolves.
Architect and evolve agentic coding systems that orchestrates LLM tool use, planning loops, sandboxed code execution, and long-horizon task completion across GitHub repositories, issues, pull requests, and Actions.
Champion responsible AI practices for autonomous coding agents, including prompt-injection defenses, permission scoping, audit logging, and human-in-the-loop review patterns that keep developers in control of changes Copilot makes on their behalf.
