Senior Engineer - Azure DevOps Agent Containers (ID:

Responsibilities

• Design, build, optimize, and maintain Docker images for Azure DevOps self-hosted build agents.
• Review and modernize existing build-agent Docker images by removing unnecessary dependencies, duplicate layers, caches, and unused tooling.
• Define a scalable and maintainable image strategy for Azure DevOps build agents used across multiple CI/CD workloads.
• Create purpose-built build agent images for different technology stacks such as Dot NET, Java, Node.js, Kubernetes, and security scanning.
• Improve Docker image build time, pull time, startup time, and overall CI/CD pipeline performance.
• Support the migration of Azure DevOps build agents from virtual machines to AKS-hosted containerized agents.
• Establish image standards, naming conventions, versioning, lifecycle management, and patching processes.
• Implement secure image management practices, including vulnerability scanning, SBOM generation, and supply-chain security controls.
• Collaborate with platform engineering and development teams to deliver standardized developer self-service build environments.
• Continuously enhance the reliability, maintainability, and security of the organization’s build platform.

What You Bring to the Table

• 6+ years of experience in Platform Engineering, DevOps, Build Engineering, or Infrastructure Engineering.
• Strong hands‑on experience designing and maintaining Docker images for CI/CD environments.
• Experience working with Azure DevOps self-hosted agents running inside Docker containers.
• Solid expertise with Azure Kubernetes Service (AKS) or Kubernetes‑based build agent environments.
• Experience building and managing ephemerous build agents.
• Strong understanding of Azure Container Registry (ACR) and container image lifecycle management.
• Hands‑on knowledge of Docker BuildKit and container image optimization techniques.
• Experience with image security tools such as Trivy, Grype, Syft, SBOM generation, or similar solutions.
• Good understanding of minimal base image strategies including Alpine, Distroless, Debian Slim, or Ubuntu Minimal.
• Experience implementing CI/CD supply‑chain security and secure container image governance.
• Knowledge of KEDA‑based agent scaling and Kubernetes‑native CI/CD execution is highly preferred.

You should possess the ability to:

• Design lean, secure, and reusable Docker images for Azure DevOps build agents.
• Optimize container images by eliminating unnecessary dependencies and reducing image complexity.
• Create multiple task‑specific build agent images instead of maintaining oversized generic images.
• Improve CI/CD pipeline efficiency through optimized image pull times, caching strategies, and toolchain packaging.
• Build and manage containerized Azure DevOps agents running on AKS or Kubernetes.
• Implement automated image scanning, vulnerability management, and SBOM generation.
• Define image versioning, governance, lifecycle management, and patching strategies.
• Troubleshoot Docker, Kubernetes, and Azure DevOps build platform issues effectively.
• Collaborate with cross‑functional engineering teams to enhance developer productivity and platform reliability.

What we bring to the table

• Opportunity to work on modernizing a large‑scale Azure DevOps build platform.
• Exposure to cloud‑native technologies including Docker, Kubernetes, and Azure Kubernetes Service (AKS).
• Opportunity to build scalable, secure, and high‑performance CI/CD infrastructure.
• A collaborative engineering environment focused on automation, platform engineering, and developer enablement.
• Hands‑on experience with modern container security, image governance, and supply‑chain security practices.
• Opportunity to work with cutting‑edge DevOps and cloud technologies including BuildKit, Azure Container Registry, KEDA, and Kubernetes.
