Ebay is looking for a DevOps Engineer (SE3) to contribute to the reliability and evolution of our Mobile DevOps platform. You will improve CI/CD systems, fleet reliability, observability, and software supply chain security for iOS and Android applications. This role involves systems engineering, collaboration across teams, and requires on-site work in Dublin.
What You'll Do
- Improve system throughput and determinism across CI/CD pipelines by reducing flakiness, optimizing parallelization, and improving cache efficiency and stage isolation.
- Increase fleet reliability and performance through capacity planning, autoscaling strategies, workload scheduling, and failure-domain analysis across macOS and Android runners.
- Strengthen observability across subsystems by instrumenting metrics and logs, building actionable dashboards, and improving time-to-detection and time-to-recovery.
- Enhance software supply chain integrity by advancing secure code signing, secrets management, artifact validation, and automated security controls within CI workflows.
- Contribute to operational excellence by participating in incident response, performing root cause analysis, and implementing systemic reliability improvements.
- Collaborate across engineering domains to evolve platform architecture, share knowledge, and continuously improve developer productivity at scale.
What We're Looking For
- Experience engineering or operating production CI/CD systems (e.g., Jenkins, GitHub Actions, GitLab CI) with an understanding of pipeline architecture and failure modes.
- Strong systems-level diagnostic skills in Linux and macOS environments, including command-line diagnostics and performance analysis.
- Proficiency in automation and scripting (e.g., Python, Bash) and familiarity with infrastructure automation concepts.
- Working knowledge of distributed systems fundamentals, including networking (TCP/IP, DNS, load balancing), resource isolation, and secure system design.
- Experience with cloud infrastructure (Azure, GCP, or equivalent) and an understanding of scalability and fault tolerance principles.
- Ability to work on-site in Dublin, collaborate across time zones, and participate in business-hours operational support.
Technical Stack
- CI/CD: Jenkins, GitHub Actions
- Platforms: macOS/Xcode, Android, Linux
- Languages/Scripting: Python, Bash
