Senior Platform Engineer with AWS, Cloud Platform

We are looking for an experienced Platform Engineer to support the existing AWS infrastructure and contribute to its ongoing modernisation and consolidation. The role combines hands on cloud engineering with a product mindset. We are not looking only for someone who can build or operate infrastructure. We need an engineer who treats the platform as a product and product engineering teams as customers, starting from developer friction rather than a preferred tool, building self service capabilities and golden paths, and proving impact with data.

The working schedule is aligned with UK business hours, from 9:00 AM to 5:30 PM UK time. Participation in an on call rota may be required.

This position includes a sign in bonus.

You will contribute to a transformation from team operated infrastructure toward a platform with clear self service capabilities. The platform is run as an internal product. Product engineering teams are its customers, and success is measured by developer experience, adoption, reliability, delivery speed, and cost.

• Design and evolve reliable AWS, Kubernetes, Terraform, and CI/CD platform capabilities for engineering teams.
• Understand developer friction through conversations, feedback, and data before choosing a technical solution.
• Build self service capabilities, golden paths, and guardrails that make the right thing easy for engineers.
• Measure outcomes such as lead time, deployment frequency, reliability, and cost to prioritise work and confirm improvements.
• Work with product engineering teams to iterate on solutions and drive platform adoption.
• Balance standardisation and controls with usability so the platform enables teams rather than adding process.
• Strengthen observability, resilience, security, and incident readiness.
• Take part in incident response, post incident reviews, and the on call rota.

• Strong hands on AWS platform engineering experience in production environments.
• Practical experience with Kubernetes, EKS, Docker, Terraform, and Helm.
• Strong CI/CD experience, particularly with GitHub Actions and reusable pipeline design.
• Experience with logging and monitoring, networking and protocols, secrets management, and service discovery.
• Experience with at least one programming or scripting language.
• Evidence of designing secure, reliable, and maintainable platform solutions.
• Experience supporting business critical services, including participation in an on call rota.
• Experience identifying developer needs and translating them into practical platform improvements.
• Experience building self service capabilities, reusable workflows, or guardrails adopted by engineering teams.
• Ability to use data and metrics to prioritise platform improvements and evaluate their impact on developer experience, reliability, delivery speed, or cost.
• Experience collaborating with engineering teams to gather feedback, iterate on solutions, and drive adoption.
• Ability to balance standardisation, security, and operational controls with developer usability.

• Experience with Honeycomb, OpenTelemetry, Prometheus, or Splunk, including SLO driven practices.
• Experience using platform engineering metrics to measure adoption, developer experience, and operational outcomes.
• Pragmatic use of AI assisted engineering tools to improve quality and productivity.
