Overview
GitHub is seeking a Senior Software Engineer to join the Git Systems Engineering team, which runs the largest code-hosting platform in the world, part of our Platform and Infrastructure organization. Our group is responsible for the services that store and serve Git repositories, both directly to users and to other layers in the GitHub software stack. We build the various microservices, protocols, proxies, and control systems that power Git operations at GitHub and operate them at scale.
Our group is highly distributed and the right candidate will thrive in an environment of asynchronous communication. We expect you to have excellent written communication skills and be able to create working relationships with coworkers in locations around the globe.
This role is focused on wide-reaching, cross-team work to improve our git code-hosting platform. This role will be involved in the design, rollout and support of highly performant, highly scalable, and highly available services to enable the next generation of AI-driven software development.
Prior experience solving problems with large-scale, distributed systems is preferred. (i.e. Petabytes of storage, millions of objects, low latency, high throughput with millions of QPS)
Responsibilities
- Design, develop, test, and ship high-quality solutions within the team’s service area, with attention to scalability, availability, and maintainability; build deep familiarity with the systems you own and apply best practices to keep code extensible and operable.
- Lead technical discussions for features in the team’s area of responsibility; produce design docs/proposals as needed; and validate approaches through targeted experiments and prototypes, incorporating stakeholder and customer feedback.
- Lead by example by writing clean, defensive, maintainable code and mentoring engineers within the immediate team on implementation details, debugging techniques, and product/service expertise.
- Provide technical leadership in code reviews to ensure changes meet GitHub and team quality standards (correctness, security, reliability, diagnosability, and maintainability), and that code is ready to merge and operate at the expected scale.
- Partner with engineering and product stakeholders to define requirements, identify dependencies, break work into deliverable milestones, and provide estimates and risk/impact tradeoffs to support prioritization and successful delivery.
- Participate in the on-call rotation for the team’s services; act as a first responder for your area of ownership; troubleshoot complex live-site issues using logs/telemetry; drive mitigations and safe deployments (including rollback plans); and write postmortems that result in measurable follow-up improvements.
- Model engineering excellence by improving developer workflows (tooling, automation, and repeatable quality checks), sharing learnings from investigations and incidents, and contributing to a collaborative team culture with strong ownership and inclusive communication.
