Senior / Staff Software Engineer, Continuous Integration

About the Role

Anthropic is seeking talented and experienced Software Engineers to join our Continuous Integration (CI) team within the Developer Productivity organisation. The CI team is responsible for the infrastructure that enables hundreds of engineers to ship code safely and efficiently to production.

Responsibilities

• Design and build highly reliable, scalable CI infrastructure that supports thousands of daily builds across multiple cloud providers
• Develop intelligent test selection systems that reduce CI time while maintaining code quality
• Build and improve incident response automation, including cluster load shedding, automatic recovery, and observability tooling
• Improve test infrastructure reliability through flake detection, quarantine systems, and test state management

You May Be a Good Fit If You:

• Have 10+ years of relevant industry experience building and operating large-scale CI/CD systems
• Have deep experience with CI orchestration tools (Buildkite, Jenkins, GitHub Actions, or similar)
• Are obsessed with developer productivity and reducing friction in the software development lifecycle
• Have experience with container orchestration at scale
• Have excellent communication skills and enjoy supporting internal partners
• Care deeply about reliability and building systems that 'never fail the same way twice'

Strong Candidates May Also Have:

• Experience with merge queues and branch management at scale
• Experience with test infrastructure, including intelligent test selection and flake management
• Experience building CLI tools and developer-facing services
• GitHub API and automation experience

Logistics

• Education requirements: We require at least a Bachelor's degree in a related field or equivalent experience
• Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time
• Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate

How we're different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles.
