Senior Platform Engineer

Join our Engineering Acceleration Team within the Technology & Innovation Group and play a key role in evolving our core infrastructure and developer platform capabilities.

We are looking for a Senior Platform Engineer to join the team to bring architectural insight, a deep understanding of modern platform engineering practices, and a passion for enabling others through automation and infrastructure. You will also mentor engineers, influence platform strategy, and engage with stakeholders across the business.  

As a Senior Platform Engineer in this team, you will: 

• Design and drive the evolution of Kubernetes clusters across on-prem and cloud environments. 

• Lead the definition and adoption of best practices for container orchestration, infrastructure-as-code, and continuous delivery. 

• Engage with engineering and infrastructure stakeholders to understand and influence technical requirements and priorities. 

• Mentor less experienced engineers and support knowledge-sharing across teams. 

• Ensure the scalability, security, and reliability of our software services in production environments 

Responsibilities: 

Platform Infrastructure Management 

• Architect, deploy and operate Kubernetes clusters (AKS/EKS/on-prem) across hybrid-cloud and virtualised environments. 

• Define and continuously improve platform architecture with a focus on scale, tenancy, and operational resilience. 

• Champion GitOps workflows and scalable deployment strategies across the organisation. 

Cloud Infrastructure & Automation 

• Help to lead the implementation of Infrastructure as Code (Terraform, Helm) for consistent and repeatable provisioning.  

• Build reusable modules and automation for developer and infrastructure teams. 

• Contribute to shared pipelines, templates, and documentation to enable self-service. 

• Develop and maintain Cloud Operators for managing application lifecycles and platform services. 

• Lead the implementation of Infrastructure as Code (Terraform, Helm) for consistent and repeatable provisioning. 

CI/CD and Software Delivery Enablement 

• Extend and manage CI/CD pipelines using Bitbucket Pipeline or Azure DevOps. 

• Support build, packaging, deployment, and lifecycle management processes. 

• Help teams adopt modern delivery practices through tooling and coaching. 

• Provide architectural input on how platform choices impact software delivery and operability. 

• Join wider Application Development squads to accelerate delivery of key projects. 

Observability, Site Reliability 

• Operate production workloads with an SRE mindset: measure reliability, define SLOs, and reduce toil through automation. 

• Lead initiatives to reduce operational toil and enhance system resilience through automation. 

• Participate in incident response, conduct root cause analysis, and feed improvements into platform design. As well as being available for escalated out of hours calls where needed. 

• Define and improve availability, performance, and scalability through platform-level metrics and service reviews. 

• Apply security best practices for Kubernetes (RBAC, network policies, secrets). 

• Liaise with internal security and compliance stakeholders to ensure governance requirements are met. 

• Drive adoption of secure-by-default practices within platform services. 

• Support secure identity, access, and secrets management integrations. 

Mentorship and Technical Influence 

• Coach and mentor engineers on platform tools, patterns, and architecture. 

• Contribute to internal documentation, training materials, and brown-bag sessions. 

• Influence cross-team decision-making through clear communication and technical reasoning. 

Skills and experience required: 

• Degree in Computer Science, Systems Engineering, or a related field. 

• Collaborative and adaptable with a platform mindset. 

• Strong interest in enabling engineering teams through infrastructure and automation. 

• Confident communicator who can explain infrastructure decisions to developers and non-specialists. 

• Works well across teams and disciplines, especially in high-performance environments. 

• Self-motivated and pragmatic with a continuous improvement approach.

Experience with: 

• Kubernetes provisioning and lifecycle management (AKS, EKS, on-prem). 

• Infrastructure as Code (Terraform, Helm).

• Containerisation and orchestration (Docker, Helm, Operators).

• Cloud platforms (Azure, AWS).

• CI/CD pipelines (Azure DevOps, Bitbucket Pipelines, GitHub Actions).

• GitOps (e.g., ArgoCD, FluxCD).

• Monitoring, logging, and alerting (Prometheus, Grafana, Loki).

• Scripting and automation (Python, Bash, etc.).

Exposure to the following would be beneficial: 

• Multi-cloud or hybrid-cloud architectures.

• Security practices for cloud-native platforms.

• Cost optimisation strategies in cloud deployments.

• Reliability-focused engineering (SLOs, SLIs, error budgets).

• Incident response practices and post-incident reviews.

• Supporting production systems and on-call readiness.

For almost 50 years, Williams Racing has been at the forefront of one of the fastest sports on the planet, being one of the top three most successful teams in history competing in the FIA Formula 1 World Championship. With an almost unrivalled heritage of engineering and racing F1 cars and unforgettable eras that demonstrate it is a force to be reckoned with, the British squad boasts 16 F1 World Championship titles to its name. 

Since its foundation in 1977 by the eminent, late Sir Frank Williams and engineering pioneer Sir Patrick Head, the team has won nine Constructors’ Championships, in association with Cosworth, Honda and Renault. Its roll call of drivers is legendary, with its seven Drivers’ Championship trophies being lifted by true icons of the sport: Alan Jones, Keke Rosberg, Nelson Piquet, Nigel Mansell, Alain Prost, Damon Hill and Jacques Villeneuve. The team has made history before and is out to make it again with a long-term mission to evolve and return to the front of the grid.
