In this role you can work from Remote, United Kingdom

As a Senior Software Engineer on the Issues Platform team at Git Hub, 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 Git Hub 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 Git Hub 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 Git Hub Issues is always available and resilient), Scalability (building extensible architecture and consistent performance at scale), and 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 Graph

QL 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.
