Overview

As a Senior Software Engineer on the Issues Platform team at GitHub, you will enhance the collaboration experience by working closely with a community of engineers and designers on a distributed, diverse and passionate team delivering the services that millions of developers depend on. In this role you will design, prototype, implement, ship and support highly performant systems with your team.

The Issues Platform team is a subteam of the broader GitHub Issues team within the Core Productivity engineering organization. Our core strategy is to invest in making Issues a reliable, fast and flexible solution that scales with the growth of our user base. We are a platform team, which means our customers are both the millions of developers who use GitHub Issues daily and the internal product teams who build features on top of our platform. We measure our success by service level objectives, the ability of partner teams to iterate rapidly on new features, and customer feedback on reliability and performance.

Our work is organized around three pillars:

• Reliability: ensuring GitHub Issues is always available and resilient.
• Scalability: building extensible architecture and consistent performance at scale.
• Developer Experience: providing clear service boundaries and reusable building blocks for partner teams.

You will contribute to projects across these pillars, from maintaining and extending our Ruby on Rails application to building new Go services that power our GraphQL APIs and REST endpoints.

We are looking for creative problem solvers and diverse thinkers, people who care about culture as well as customers and features. We believe that how we do things is as important as what we do. Big vision, a common purpose, passion for quality, curiosity, dedication, and investment in fun and collaboration are what lead to great results. Great products reflect the teams that build them.

GitHub is the world’s leading AI‑powered developer platform. Our values guide how we work: Customer‑obsessed, Ship to learn, Growth mindset, Own the outcome, Better together, and Diverse and inclusive. We create clarity, generate energy, and deliver success.

Responsibilities

• Design, develop, test and ship high‑quality technical solutions that scale across multiple GitHub services.

• Design and implement GraphQL APIs and REST endpoints that serve as building blocks for product teams to build new features.
• Maintain and extend Ruby on Rails applications while contributing to new Go services.
• Drive improvements to service reliability through instrumentation, monitoring, and SLO management.
• Lead discussions for technical solutions within the team’s area of responsibility and create proposals for architecture.
• Drive identification of dependencies during the design of products, applications, services, or platforms.
• Participate in incident response, conduct root cause analysis, and contribute to postmortems.
• Drive efforts to integrate instrumentation for gathering telemetry data on system behavior such as performance, reliability, availability, and usage.
• Utilize CI/CD tools to set up automated pipelines for continuous integration and delivery.
• Become intimately familiar with the systems you build and take pride in writing maintainable code.
