Essential functions

Key Responsibilities

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 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:

  • 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.

Qualifications

Essential 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.

Would be a plus

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.
