• Taking ownership of CI/CD pipelines, improving deployment speed, reliability and automation.
• Building and enhancing automated testing frameworks across unit, integration and end-to-end testing.
• Working with AWS, Infrastructure as Code (Terraform/CloudFormation) and containerised environments.
• Improving monitoring, observability and release management across production systems.
• Leveraging AI-assisted development tools to accelerate engineering delivery and improve code quality.
• Contributing to architectural decisions, technical standards and engineering best practices.
• Collaborating with Software Engineers, QA, Infrastructure and business stakeholders to deliver commercially impactful solutions.

What We're Looking For

• Strong commercial experience in C#/.NET software engineering, ideally across both frontend and backend development.
• Hands-on experience building, managing and improving CI/CD pipelines.
• Strong cloud infrastructure experience, ideally AWS.
• Experience with Infrastructure as Code tools such as Terraform or CloudFormation.
• Knowledge of Docker, containerisation and modern deployment practices.
• Experience developing APIs, microservices and scalable web applications.
• A strong understanding of automated testing, software quality and production reliability.
• An interest in AI-assisted development tools and modern engineering practices.
• Excellent problem-solving skills, technical ownership and stakeholder communication.

Why Join?

AI-Driven Engineering: Work for a business actively investing in AI and automation, with a genuine commitment to improving engineering productivity.

Technical Ownership: Take responsibility for how software is built, tested, deployed and monitored, with the freedom to influence technical direction.

Modern Engineering Challenges: Work on commercially critical platforms where performance, scalability and reliability have a direct business impact.

Career Development: Join an established engineering function, working closely with the Head of Web Development and experienced technical teams.
