Senior Dev Ops Engineer

Job summary

We're MI6, also known as the Secret Intelligence Service (SIS). Our mission is to protect the security and economic wellbeing of the UK from overseas threats such as regional instability, terrorism, and cyber‑attacks. Working across the globe and in close partnership with MI5 and GCHQ, we help the Government to counter these threats through the provision of secret intelligence. A role in MI6 will see you providing vital support to this work, within a supportive and encouraging environment that puts the emphasis on teamwork.

Job description

Enhancing how we operate today will better prepare us for the challenges of tomorrow. That’s why we’re creating dedicated teams focused on bringing Artificial Intelligence (AI) into some of our most mission‑critical areas. As a Senior DevOps Engineer, you’ll play a key role in bridging development and operations by enabling teams to deliver software reliably, securely and at pace.

You’ll help design, build and run a bespoke internal Cloud platform, ensuring the smooth operation of systems and infrastructure that support AI, ML Ops and wider engineering teams. You’ll focus on embedding DevOps practices such as continuous integration, continuous delivery, infrastructure automation and monitoring, creating reliable pipelines and tooling that underpin modern engineering ways of working.

With a primary focus on delivery and operational excellence, you’ll support the creation of a scalable, reliable and secure Cloud‑based platform. You’ll build and maintain CI/CD pipelines, develop infrastructure as code, deliver DevOps automation, and ensure systems are observable, resilient and well monitored. In doing so, you’ll create shared tooling and services that teams across South can use securely and effectively.

Working closely with software engineers, product managers and ML Ops teams, you’ll promote a strong DevOps culture by improving collaboration, reducing friction between teams and continuously improving how services are built, deployed and operated. Whether troubleshooting live issues, improving platform reliability or adopting industry best practice, you’ll deliver practical, high‑quality solutions that support the organisation’s mission.

Person specification

You’ll be an experienced DevOps or platform‑focused engineer, with demonstrable experience designing, automating and operating Cloud‑based systems in complex environments. You’ll bring strong experience of infrastructure as code, CI/CD, configuration management, containerisation and monitoring, alongside hands‑on experience with Cloud platforms such as AWS, Azure or Google Cloud.

You’ll be someone seeking to move into a senior role providing technical direction and mentoring to less experienced engineers. Adaptable, collaborative and knowledgeable, you’ll be a problem-solver with a knack for troubleshooting. Importantly, you’ll be keen to learn, with an eye on emerging trends, and excited by the prospect of significant upskilling in AI and ML Ops.

Please note, you don’t need any existing AI expertise beyond a foundational understanding. Instead, you’ll bring a genuine passion and some evidence of self-study that supports your interest.

Benefits
