Senior Platform Engineer

Build the platform that powers engineering at scale

We're looking for a Senior Platform Engineer to help reimagine how software moves from commit to production in an AI-first world. Our focus is extending our Internal Developer Platform to support AI-generated software, removing bottlenecks that slow engineers down, and building the guardrails, automation and governance needed to safely accelerate delivery 'll be building platform capabilities that influence the day-to-day experience of 1,000+ engineers, shaping how software is built, tested, secured and released across the organisation.

Working across Git Hub, Kubernetes, AWS, EKS, Terraform, Git Ops and CI/CD, you'll help challenge traditional assumptions about software delivery and engineer the next generation of developer workflows. Many of today's delivery models were designed for a world where humans authored most of the code.

This role is for someone who enjoys building more than maintaining. Someone who can take an idea from concept to POC to production. Someone who sees friction, questions why it exists, and then automates it away.

We operate within a broader platform engineering function responsible for developer experience, Kubernetes and platform support. This role sits in the team focused on our internal developer platform, the tooling engineers use to provision infrastructure, build pipelines and deploy into our cloud environment. Our platform is used by multiple engineering teams across the business and is central to how we deliver software  team currently includes engineers across multiple seniority levels, and we are adding another senior engineer to strengthen our technical depth.

• We will rely on you to design and implement infrastructure using code, enabling consistent, repeatable and scalable environments across our cloud platform.
• We will expect you to build and optimise cloud-native deployment pipelines that support high-frequency, low-risk releases.
• We will look to you to enhance our internal developer platform, improving how engineers provision infrastructure and deploy services.
• We will count on you to troubleshoot complex platform and performance issues across distributed systems and lead root-cause investigations.
• We will expect you to contribute to architectural decisions across microservices, event-driven systems and cloud-native patterns.
• We will rely on you to mentor other engineers and raise the engineering standard across the team.

We build platforms for engineers, not end-users. That means every decision is grounded in performance, reliability and usability at scale.

We give you the opportunity to:

• Influence platform architecture across cloud, containers and automation.
• Build tools that are used across engineering teams, not just a single product.
• Work on complex distributed systems with real production scale.
• Introduce new capabilities, including practical AI-driven enhancements to the developer experience.
• Contribute as a senior technical contributor without needing formal line management.

• We are looking for deep experience in platform engineering, site reliability or Dev Ops engineering.
• We expect at least five years of hands‑on experience working in cloud environments.
• We require strong experience building infrastructure as code using tools such as Terraform, Cloud Formation or similar.
• We are looking for solid experience building and maintaining CI/CD pipelines, for example Jenkins or Git Hub Actions.
• We expect strong hands‑on experience with containers and orchestration, particularly Kubernetes.
• We are looking for experience designing and operating cloud‑native systems, including microservices and event‑driven architectures.
