We do not oversell. - Join the on-call rotation. What You'll Bring: - 2 or more years in technical product support or software engineering - Hands-on use of AI tools at work. You write clear instructions for AI, review the results, and take responsibility for them. You have built or tested AI agents or workflows. - Experience finding the cause of problems in cloud or distributed systems. You read logs to trace what went wrong. - Hands-on experience with Docker and Kubernetes. You have used tools like kubectl to find why an application or cluster is failing. - Experience supporting self-hosted or on-premises software. You have used tools like Helm and support bundles to find why an installation is failing. - Hands-on experience with build, test, and deploy automation. You have written automated tests and set up a CI/CD pipeline for a project. - Knowledge of iOS application testing and code signing. - Working knowledge of CI/CD, Git, and the Linux command line.

We use technology to support our recruiting team so they can spend more time on what matters most: getting to know you. Where we may use AI - Job descriptions and messaging: AI may help draft job descriptions and role-specific messaging so they are clear and accurate. - Application review: For some roles, we use an AI tool to review applications, including resumes and application responses, against criteria our hiring team sets for the role. The tool generates a fit score and summary to help recruiters organize and prioritize applications. - Interview notes: With advance notice, an AI note-taking tool may join interviews to record, transcribe, and summarize the conversation. This lets interviewers focus on talking with you. You will be told before each interview, and you may opt out at any stage by letting your recruiter know. If you opt out, the tool will not join, and your candidacy is not affected. - Outreach: AI may help draft candidate outreach and scheduling messages, which our team reviews before sending. Our commitment AI does not make hiring decisions at CircleCI. Our recruiters and hiring teams review candidates and make every decision to advance or reject an application. No candidate is rejected based solely on an AI score. We have tools and processes in place to test for bias and to review how these tools perform, and we adjust our approach as AI technology and the laws that govern it change. ## Your choices You can ask for human-only review of your application, opt out of AI interview note-taking, request an accommodation, or ask questions about how we use AI.
