Senior Software Engineer - Git Systems Engineering (GitHub - CoreAI)

About the role

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.

Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience. These requirements include but are not limited to the following specialized security screenings: Understanding of production system monitoring and observability.

Ability to think critically about both system design and software engineering concepts and blend those perspectives pragmatically based on project needs. 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 product.
