DevOps Engineer

Requirements

• 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.
