Senior Software Engineer DevX

AI-powered and agentic developer tools are changing what is possible creating an opportunity to rethink how engineers write test review ship and operate software. At Reddits scale that means building tools that are not only more intelligent but also faster more reliable easier to use and grounded in strong engineering fundamentals.

This role sits at the center of that work: designing and building the platforms services systems and workflows that improve how Reddit engineers develop software. Youll work across backend systems infrastructure developer tooling and AI-powered workflows to solve problems that affect hundreds of engineers across the company. Youll collaborate closely with teams that own CI/CD infrastructure security and product systems as well as engineering teams across Reddit that rely on these tools every day. Were looking for someone with strong engineering fundamentals infrastructure experience product judgment and a real interest in developer experience and developer productivity.

Some of our present and future challenges include:

• Designing and building the next generation of developer tooling including agentic and AI-powered workflows.
• Improving developer velocity confidence and service reliability across Reddit Engineering.
• Building tools and workflows that make writing testing reviewing and shipping code easier.
• Scaling our infrastructure services APIs and processes to serve a growing engineering organization.
• Understanding internal users needs and turning that understanding into meaningful product and technical improvements.
• Building integrations across Reddits existing infrastructure CI/CD security source control deployment and operational systems.
• Investigating building and integrating novel technologies where they solve real problems for developers.

Youll draw on your backend infrastructure and platform engineering experience to build developer tooling that is scalable reliable easy to use and valuable to a growing engineering organization. Youll work directly with engineers across Reddit to understand their pain points shape solutions incorporate feedback and communicate the impact of the teams work.
