Senior DevOps Engineer - Build Pipelines

We are partnering with a global asset management organisation to modernise and standardise build and deployment pipelines across a large application estate. The organisation is looking for Senior DevOps Engineers to join a high-performing engineering squad focused on improving CI/CD, automation, security and deployment practices across the business. The Engagement The team is undertaking a major initiative to standardise and modernise build and deployment pipelines across a diverse application estate. The environment consists primarily of C#/.NET and Python services, with different teams having historically adopted their own build conventions, deployment mechanisms and tooling. The objective is to establish a small number of opinionated, reusable and well-supported pipeline patterns that engineering teams can adopt with minimal bespoke configuration. You Will Work Closely With Application Engineering Teams To Design, Implement And Roll Out These Standards, With a Strong Focus On Repeatable CI/CDAutomationSecurityQuality gatesObservabilityDeployment consistencyDeveloper experiencePlatform engineering principles This is a hands-on engineering role, rather than a traditional operational DevOps position. The Role As a Senior DevOps Engineer, you will take ownership of designing and implementing reusable build and deployment capabilities across the organisation. You will work as part of a small team of experienced DevOps engineers, collaborating directly with application developers and technical stakeholders. A key part of the role will be creating standardised GitHub Actions workflows that can be consumed by multiple development teams while supporting different applications and deployment environments. You will also play a significant role in migrating existing pipelines away from legacy tooling and establishing modern CI/CD practices across the estate. Responsibilities Key Responsibilities CI/CD & Pipeline Engineering Design and develop reusable GitHub Actions workflows and pipeline templates.Build standardised CI/CD patterns covering:BuildUnit testingIntegration testingStatic analysisSecurity scanningPackagingArtifact managementPromotionDeploymentCreate modular and maintainable pipeline components for multiple application teams.Establish consistent pipeline standards across different technology stacks.Improve build performance, reliability and developer experience.Automate repetitive build and deployment processes. GitHub Actions & Enterprise GitHub Develop enterprise-grade workflows using GitHub Actions.Work with reusable workflows, actions, secrets, environments and deployment controls.Establish appropriate controls around pipeline permissions and access.Help application teams migrate existing processes into standard GitHub-based workflows.Promote best practices around source control, branching, releases and deployment automation. Azure DevOps Migration Migrate existing Azure DevOps pipelines onto standardised GitHub Actions workflows.Analyse existing pipeline functionality and ensure important capabilities are retained during migration.Identify opportunities to simplify and improve legacy build processes.Support development teams throughout the migration and adoption process. Deployment Automation Develop deployment patterns supporting both cloud and on-premise environments.Work with Windows-based infrastructure, including long-lived VM and server environments.Support deployment into IIS and Windows Server environments.Integrate deployment tooling such as Octopus Deploy.Develop automation using PowerShell and Python.Build repeatable promotion mechanisms across development, testing and production environments. Security & Quality Embed security and quality directly into the standard pipeline. You Will Work With Technologies And Practices Including SonarQubeSASTDASTDependency scanningCVE / vulnerability scanningContainer/image scanningImage signingSecurity and quality thresholdsAutomated quality gates The objective is for security and quality controls to be enabled by default across the application estate. Observability Integrate pipeline and deployment processes with appropriate monitoring and observability tooling.Help teams understand build and deployment health.Work with technologies such as:PrometheusGrafanaDatadogEstablish useful metrics and visibility around pipeline execution and deployments. Engineering Enablement Work directly with application engineering teams to implement new standards.Provide practical examples and reference implementations.Produce clear technical documentation.Help teams adopt reusable pipeline patterns.Act as a technical advocate for modern DevOps and platform engineering practices.Raise engineering standards for CI/CD across the organisation.
