Role Summary

The fast-growing NSG DevOps-Buildsystem team is responsible for supporting our NSG Product teams to deliver the build system infrastructure required for the various engineering teams.

As an DevOps-Buildsystem Engineer, you will join a lean and focused DevOps team supporting a mature, mostly on-premises build and deployment infrastructure. This role is ideal for someone looking to grow their automation and CI/CD skills, develop deep system-level knowledge, and take ownership of real-world infrastructure — not just cloud abstractions. You'll work across various tools and systems, help improve build performance and reliability, and collaborate with globally distributed developers.

• Own and maintain NSG's CI/CD pipelines and build systems
• Continuously improve our existing build framework (automation, monitoring, alerting, diagnostics)
• Investigate and resolve operational issues quickly and thoroughly
• Help optimize build and test times through profiling and parallelization
• Implement DevOps best practices in day-to-day work
• Participate in incident response and post-mortem reviews

• 4-6 yrs of experience working on DevOps/Build & Release
• Strong analytical and troubleshooting skills
• Solid understanding of Git and branching strategies
• Comfortable with Linux shell and basic system concepts
• Ability to write and debug scripts in Bash and Python
• Familiarity with Infrastructure as Code and/or configuration management tools (Terraform, Ansible, Chef, etc.)
• Familiarity with monitoring/logging platforms (Elasticsearch, Splunk, LogicMonitor, etc.)
• Hands-on experience supporting or modifying CI/CD pipelines

• Nice to Have:
• Experience with CI/CD tools (Jenkins, TeamCity, Bamboo, etc.)
• Exposure to on-prem virtualization platforms (Proxmox, VMWare, etc.)
• Basic networking knowledge (e.g., DNS, routing, firewalls)
• Experience with GitHub Actions and GitHub APIs
• Exposure to Artifactory, SonarQube, or Black Duck
• Exposure to cloud services (AWS, Azure, GCP)—a plus, but not central to the role
