Build the platforms behind critical digital services.
Are you a Senior or Lead Platform Engineer who thrives on solving complex infrastructure challenges, building production-grade platforms, and shaping the engineering practices that enable teams to deliver at scale? We are looking for experienced Platform Engineers to help design, build and continuously improve critical digital services used across the Nation. You'll work on platforms that must remain secure, resilient and observable under significant demand, helping to modernise essential services that make a real difference.
You'll join a highly collaborative engineering community where knowledge sharing, continuous improvement and technical excellence are at the heart of everything we do.
The Opportunity
As a Senior Platform Engineer, you'll play a key role in designing, building and evolving modern cloud platforms that enable engineering teams to deliver safely, rapidly and reliably. This is a hands-on technical leadership role where you'll combine deep engineering expertise with strategic influence. You'll work closely with delivery teams, architects and client stakeholders to define platform strategy, establish engineering standards and build reusable capabilities that improve the developer experience. You'll remain close to the technology, actively contributing to architecture, code, automation and operational improvements while mentoring and supporting other engineers.
What You'll Be Doing
- Designing secure, scalable multi-cloud landing zones, primarily within AWS.
- Building GitOps-driven platforms and Internal Developer Platforms (IDPs) that provide true self-service capabilities for engineering teams.
- Modernising legacy environments into cloud-native architectures.
- Creating unified observability solutions using OpenTelemetry, Prometheus, Grafana and modern APM tooling.
- Driving improvements in reliability, operability and platform performance through Site Reliability Engineering (SRE) practices.
- Implementing secure CI/CD pipelines with a strong focus on DevSecOps and software supply-chain integrity.
- Delivering event-driven automation and infrastructure capabilities.
- Driving FinOps initiatives and optimising cloud consumption across large-scale estates.
- Applying platform-as-a-product principles to create reusable, scalable engineering capabilities.
Technical Leadership & Influence
As a senior member of the engineering team, you will:
- Act as a senior technical authority, influencing platform strategy, architecture and governance.
- Lead technical workshops, architecture discussions and design reviews with stakeholders and delivery teams.
- Define and evolve engineering standards covering security, reliability, observability, CI/CD and operational excellence.
- Establish Service Level Objectives (SLOs), improve reliability and facilitate incident reviews and continuous improvement activities.
- Champion platform engineering best practices and help teams adopt them successfully.
- Coach and mentor engineers through pairing, technical leadership and knowledge sharing.
- Drive platform-as-a-product thinking, establishing golden paths and self-service capabilities that improve developer experience.
- Remain hands-on by contributing to designs, code reviews, automation and complex technical problem solving.
What We're Looking For
Essential Experience
- Significant experience designing, building and operating cloud-native platforms in enterprise or large-scale environments.
- Strong experience with AWS, including multi-account architectures and secure landing zones.
- Experience building and operating Kubernetes platforms, particularly EKS (AKS experience also beneficial).
- Expertise in Infrastructure as Code using tools such as Terraform.
- Strong understanding of CI/CD, DevSecOps and modern software delivery practices.
- Experience implementing observability solutions using tools such as OpenTelemetry, Prometheus and Grafana.
- Strong knowledge of cloud security, identity, networking and platform reliability.
- Experience leading technical discussions and influencing engineering direction across multiple teams.
- Proven ability to mentor engineers and provide technical leadership within multidisciplinary teams.
Desirable Experience
- Experience with Azure and/or Google Cloud Platform.
- Experience building Internal Developer Platforms and self-service engineering capabilities.
- Knowledge of GitOps tooling such as Argo CD or Flux.
- Experience applying Site Reliability Engineering (SRE) practices.
- Experience driving FinOps initiatives and cloud cost optimisation.
- Experience modernising legacy estates and delivering large-scale transformation programmes.
- Familiarity with event-driven architectures and platform automation.
- Experience working within highly regulated or secure environments.
