You'll be working on a range of internally developed applications, enterprise integrations and automation tooling, helping to build and improve technology used across a large-scale global environment.

The Role

You’ll be joining a collaborative engineering team responsible for developing and supporting a suite of bespoke applications, internal platforms and automation solutions.

The role is predominantly software engineering, with approximately 60% of your time spent developing in C#/.NET, alongside involvement in infrastructure automation and IaC.

Key responsibilities include:

• Design, develop and maintain internal applications, services and tooling using C# and .NET.
• Build software solutions and integrations from scratch, focusing on quality, scalability and reusability.
• Develop and maintain APIs and integrations across a range of enterprise technologies.
• Contribute to infrastructure automation and Infrastructure as Code initiatives.
• Work with technologies such as Ansible and PowerShell to streamline infrastructure processes.
• Support and improve CI/CD pipelines and deployment processes.
• Collaborate with wider engineering and infrastructure teams to identify challenges and develop effective technical solutions.
• Take ownership of existing applications while contributing to new development projects.

What We're Looking For

We're looking for a hands-on Software Engineer with a solid C#/.NET background and an appreciation for infrastructure and automation.

• 3+ years of commercial C#/.NET development experience.
• Ability to design, build and develop applications from scratch.
• Strong understanding of software engineering principles and writing clean, maintainable code.
• Some experience or exposure to infrastructure, automation or Infrastructure as Code.
• Familiarity with source control, CI/CD pipelines and modern development practices.
• Strong problem-solving skills and the ability to work independently.
• Excellent communication skills and a collaborative approach to engineering.
• Ansible, PowerShell or other infrastructure automation technologies.
• Terraform, Bicep or similar Infrastructure as Code tools.
• REST APIs and enterprise systems integration.
• Windows Server and Active Directory.
• VMware or virtualisation technologies.
• GitHub Actions, GitLab or Azure DevOps.

The Opportunity

• Work on bespoke applications and software used across a global technology environment.
• Take ownership of development projects from initial design through to delivery.
• Develop your skills across both software engineering and infrastructure automation.
• Work alongside an experienced, collaborative engineering team.
• Get involved in a varied technical environment where your software development skills will continue to be utilised and developed.
