Senior Software Engineer

Join the team shaping the future of project planning and tracking on GitHub. As a Senior Software Engineer on Planning and Tracking, you will design, prototype, implement, ship, and support highly performant user experiences, including the agentic and Copilot-powered workflows that are reshaping how teams plan and track work across GitHub Issues and Projects. You will also help uncover and solve the foundational scaling and user-experience problems that make this possible.

• Take ownership of GitHub.com, contributing to and improving the code base from day one.
• Write, review, and maintain code primarily in JavaScript (React, TypeScript) and Ruby (Rails).
• Write architecture briefs and proposals, carry out code experiments, and build prototypes aimed at planetary scale.
• Foster technical growth across the team by researching new approaches, sharing insights, and guiding their adoption.
• Coordinate with engineering and product leads to define, prioritize, and task projects that meet business objectives.
• Provide technical leadership, mentorship, pairing opportunities, and code reviews.

Qualifications

• 6+ years of software engineering experience delivering production software.
• Hands-on experience with modern web stacks, ideally React, TypeScript, and Rails.
• Experience shipping customer-facing features at scale, with a strong customer focus and a data-driven approach.
• Excellent written communication suited to a distributed, async-friendly team.
