Senior Platform Engineer

Build the future of engineering in financial services

Our client in the financial services industry is looking for a highly technical Senior Platform Engineer to help transform how software is built, secured, tested and deployed across a large-scale engineering environment.

You will contribute to the evolution of an Internal Developer Platform supporting more than 1,000 engineers, enabling faster, safer and more consistent software delivery through automation, cloud-native technologies and AI-enabled engineering practices.

The focus is on removing engineering bottlenecks, enabling developer self-service and introducing the automation, security guardrails and governance required to accelerate delivery within a complex, business-critical environment.

Working across AWS, Amazon EKS, Kubernetes, GitHub, Terraform, GitOps and CI/CD, you will design and implement scalable platform capabilities that improve developer productivity while supporting enterprise security, operational resilience and reliability.

This is an opportunity for a hands-on engineer who enjoys solving complex technical challenges, building innovative solutions and taking ideas from concept and proof of concept through to production.

Key responsibilities

• Design, implement and optimise scalable cloud infrastructure using Infrastructure as Code (IaC), ensuring consistency, security and repeatability across environments.

• Build and enhance automated CI/CD pipelines to support reliable, efficient and controlled software releases.

• Develop and evolve the Internal Developer Platform, enabling engineering teams to provision infrastructure and deploy applications through self-service capabilities.

• Engineer and optimise Kubernetes-based platforms and containerised workloads, particularly within AWS and Amazon EKS environments.

• Implement GitOps practices and deployment automation to improve release consistency, traceability and operational control.

• Establish automated security controls, governance mechanisms and platform guardrails across the software delivery lifecycle.

• Explore and implement AI-enabled engineering capabilities, including workflows that support the safe and efficient delivery of AI-generated software.

• Troubleshoot complex infrastructure, platform and distributed-system issues, leading root-cause investigations and driving permanent resolutions.

• Contribute to technical architecture and engineering standards across cloud-native platforms, microservices and event-driven systems.

• Improve platform observability, performance, scalability, availability and operational resilience.
