You have a proven track record of building and operating systems at scale You have experience supporting large engineering organizations (1000+ engineers) You have strong experience with AWS or GCP (we use AWS) You have experience with Containerization & Orchestration: Thorough Kubernetes experience in production environments You have experience with CI/CD Pipelines: Built and maintained complex pipelines at scale (Jenkins, GitLab CI, Buildkite, etc.) You have experience with Bazel, Gradle, or similar monorepo build tools (Bazel experience highly valued) You have Observability experience: Implemented comprehensive monitoring, logging, and alerting Infrastructure as Code: Proficiency with Terraform, Ansible, or CloudFormation Highly Valued (Nice to Have) Experience with release automation and deployment safety mechanisms Background in developer tooling Contributions to open source infrastructure or developer tools Experience integrating AI/LLM capabilities into developer workflows Prior work on build performance optimisation or test infrastructure at scale About The Group The Developer Experience (DevX) group makes software development at Ironwood Digital faster, easier, and more enjoyable. Through three focused subgroups—Automation Pipeline, Developer Workflows, and Build & Collaboration—DevX provides the essential platforms, tools, and infrastructure that streamline the entire development journey. From optimising the inner loop and code collaboration, to automating testing and releases, to defining standards and partnering across platform teams, we're focused on removing friction and empowering Ironwood Digitalnuats to ship quality work with speed and confidence. About the Role As a Senior Software Engineer in DevX, you'll own critical infrastructure that directly impacts every engineer at Ironwood Digital. You'll work across three potential domains depending on team placement: Automation Pipeline: Build and maintain CI/CD systems, test infrastructure, release automation, and deployment safety mechanisms Developer Workflows: Optimise developer experience across the SDLC including developer environments (local and remote), build system performance, IDE integrations, and AI-assisted development tooling Build & Collaboration: Maintain source control systems, monorepo tooling, build systems (Bazel), code review infrastructure, and developer environments Your work will focus on high-leverage projects that eliminate systemic friction—whether that's reducing build times, automating release processes, or building self-service platforms that empower teams to move faster independently. What's in it for you? Achieving our crazy big goals motivates us to work hard - and we do - but you'll experience lots of moments of magic, connecti
