Build & Deployment Engineer

Build & Deployment Engineer - C#/.NET, Octopus Deploy & Secure Coding City of London - Hybrid (4 Days on-site, 1 day WFH each week) Inside IR35 Contract Are you a build and deployment engineer who can open up the C# code behind a pipeline and fix it yourself? That combination is exactly what's needed here. You'll join the Platform Engineering function of one of the world's largest financial groups, owning the on-premises toolchain that takes software from source code to production. GitHub Enterprise, TeamCity, JFrog Artifactory and Xray, and Octopus Deploy, all integrated with ServiceNow change and vulnerability management. In a regulated banking environment, every build and deployment has to be secure, repeatable, traceable and auditable - and making that happen is your job. Alongside the platform work, you'll take technical ownership of secure coding standards: turning security policy into practical engineering controls that development teams inherit by default, rather than having to build for themselves. There's also a live migration of applications from legacy tooling onto Octopus Deploy to get stuck into. What You'll Be Doing Engineering, administering and supporting the on-premises build, packaging, artefact and deployment toolchain Building and maintaining automated CI/CD pipelines and standard templates for application teams, across Windows and Linux environments Writing, reviewing and troubleshooting the C#/.NET code behind internal deployment integrations, APIs and automation tooling Diagnosing complex build and deployment failures across code, dependencies, build agents, artefact repositories and target environments Migrating applications from legacy deployment tooling onto Octopus Deploy Defining and embedding pipeline security controls - SAST, SCA, dependency scanning, secrets detection and artefact scanning (GitHub CodeQL, Dependabot, JFrog Xray and Curation) Managing software supply-chain controls: approved repositories, open-source governance, package lifecycle, traceability and SBOM Integrating deployment automation with change and release management, including segregation of duties and audit evidence Working with Cyber Security, Risk and Control and development teams to onboard applications and remediate vulnerabilities Supporting platform upgrades, patching, resilience, DR, monitoring and incident response What You'll Bring Strong hands-on experience of enterprise software build, packaging and deployment engineering Strong C# development skills and a solid understanding of .NET Framework and modern .NET build and deployment - this is essential Practical experience with Visual Studio, MSBuild, NuGet, IIS, Windows services and REST APIs Administration or engineering experience with at least two of: Octopus Deploy, TeamCity, GitHub Enterprise, JFrog Artifactory, JFrog Xray, Azure DevOps Server Strong PowerShell, plus working knowledge of Bash/shell scripting Good understanding of Git workflows, artefact repositories, package versioning and environment promotion Experience implementing secure coding controls (SAST, SCA, secrets detection) and a good grasp of secure development principles, including authentication, secrets management, certificates and TLS Windows Server and on-premises hosting knowledge, working knowledge of Linux deployment patterns, and SQL Server database deployment (e.g. DACPAC) Experience working within formal change, incident and release management in a controlled, regulated environment Desirable: ASP.NET/ASP.NET Core, Entity Framework, NUnit/xUnit, ServiceNow integration, Terraform, Docker/Kubernetes, OWASP, SBOM standards, CyberArk This is a chance to own the build and deployment platforms at the heart of a top-tier financial services technology function, and to shape how secure coding is done across it.
