Senior DevOps Engineer

Role Summary
The Senior Applications DevOps Engineer will play a pivotal part in enabling secure, scalable, and efficient software delivery on the Microsoft Azure platform. Operating within the Application DevOps Team, this role focuses specifically on automating build, test, and deployment workflows to bridge the gap between development and operations.
The successful candidate will leverage deep expertise in Azure DevOps to orchestrate CI/CD pipelines for a diverse range of architectures, including .NET web applications, serverless functions, and mobile solutions. This role requires a distinct focus on application lifecycle automation, while collaborating closely with the Infrastructure Team to ensure alignment with the underlying Azure environment foundations.
Who we want to work with
We are looking for more than just a skilled DevOps engineer for this role - we are looking for someone who will act as a true leader within the team. The nature of our work requires individuals who can navigate ambiguity, make sound technical decisions, and take ownership from idea through to delivery and beyond. This role is not about waiting for perfectly defined requirements or relying on constant direction; it’s about actively shaping solutions, contributing to the direction of the platform, and driving meaningful outcomes. By combining strong communication, healthy scepticism, and product awareness, you will help ensure we build the right things in the right way -
balancing speed, quality, and long-term value. Ultimately, we want someone who doesn’t just deliver code, but who elevates the team, influences decisions, and plays a key role in building a scalable, globally aligned platform.
