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.

Key Responsibilities

You Will Work Closely With Application Engineering Teams To Design, Implement And Roll Out These Standards, With a Strong Focus On

• Repeatable CI/CD
• Automation
• Security
• Quality gates
• Observability
• Deployment consistency
• Developer experience
• Platform 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.

CI/CD & Pipeline Engineering

• Design and develop reusable GitHub Actions workflows and pipeline templates.
• Build standardised CI/CD patterns covering:
  • Build
  • Unit testing
  • Integration testing
  • Static analysis
  • Security scanning
  • Packaging
  • Artifact management
  • Promotion
  • Deployment
• Create 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

• SonarQube
• SAST
• DAST
• Dependency scanning
• CVE / vulnerability scanning
• Container/image scanning
• Image signing
• Security and quality thresholds
• Automated quality gates

The objective is for security and quality controls to 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:
  • Prometheus
  • Grafana
  • Datadog
• Establish 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.

Technical Environment

CI/CD

• GitHub Enterprise
• GitHub Actions
• Azure DevOps
• Octopus Deploy

Cloud & Infrastructure

• Microsoft Azure
• Windows Server
• Windows VMs
• IIS
• On-premise infrastructure
• Hybrid environments

Automation & Scripting

• PowerShell
• Python
• Bash or other scripting languages beneficial

Observability

• Prometheus
• Grafana
• Datadog

Security & Software Supply Chain

• SonarQube
• Snyk or equivalent
• SAST
• DAST
• Dependency/CVE scanning
• Image/container signing
• Software supply-chain security

Application Technologies

The Pipelines Will Primarily Support

• C# / .NET
• Modern .NET
• Legacy .NET
• Python
• WPF
• WCF

You do not need to be an application developer, but experience supporting pipelines for .NET and/or Python applications would be highly valuable.

Required Skills & Experience

• Strong commercial experience as a DevOps Engineer, Platform Engineer, Build Engineer or similar.
• Strong hands-on experience building and maintaining CI/CD pipelines.
• Excellent experience with GitHub Actions.
• Experience creating reusable workflows, templates or pipeline frameworks.
• Strong understanding of CI/CD architecture and best practices.
• Experience working with GitHub Enterprise or large-scale GitHub environments.
• Experience with Azure DevOps Pipelines.
• Experience migrating or modernising legacy CI/CD pipelines.
• Strong scripting and automation skills using PowerShell and/or Python.
• Experience working with Windows-based environments.
• Strong understanding of automated testing and quality gates.
• Experience integrating security tooling into CI/CD pipelines.
• Good understanding of software supply-chain security and dependency management.
• Experience working with enterprise development teams and complex application estates.
• Strong communication skills and the ability to work directly with developers and technical stakeholders.

Nice to Have

Desirable Experience

Experience With Some Of The Following Would Be Advantageous

• Octopus Deploy
• Microsoft Azure
• IIS
• On-premise Windows infrastructure
• Prometheus
• Grafana
• Datadog
• SonarQube
• Snyk
• SAST / DAST tooling
• Containerisation and image signing
• .NET build pipelines
• Python application pipelines
• Infrastructure as Code
• Docker
• Kubernetes
• Artifact repositories
• Release management
• Platform engineering
• Developer self-service platforms

The Ideal Candidate

The ideal candidate is someone who goes beyond simply maintaining existing pipelines.

You Should Be Comfortable Asking

"How can we build this once and allow every engineering team to use it?"

You will ideally have experience taking fragmented or inconsistent CI/CD environments and turning them into simple, reusable and scalable engineering platforms .

We Are Particularly Interested In Engineers Who Can Combine

• Deep technical DevOps expertise
• Strong automation skills
• CI/CD architecture
• Security awareness
• Enterprise-scale engineering experience
• Developer enablement
• A pragmatic, hands-on approach

You should be comfortable getting into the detail, writing the automation yourself and working directly with development teams to make it successful.
