GitHub is growing its Engineering team and seeks experienced professionals to elevate our software engineering efforts. As a Senior Software Engineer at GitHub, you will architect and deliver high-performance systems that power collaboration for millions of developers. You will drive technical execution from design through production, leading initiatives across distributed teams.
Within GitHub’s ecosystem, Actions powers automation for millions of developers worldwide, enabling them to build, test, and deploy code directly from their repositories. As the backbone of CI/CD workflows across GitHub, Actions processes billions of jobs monthly, from simple builds to complex deployment pipelines spanning multiple environments. Our team owns the core infrastructure and services that make this possible, ensuring reliability at massive scale. We're a group of engineers passionate about developer productivity, tackling challenges in distributed systems, container orchestration, security, and cloud infrastructure. You'll work alongside talented colleagues who value collaboration, operational excellence, and building products that developers love.
