What You’ll Build & Deliver
You’ll help design, build, run and improve the platforms behind critical government services, systems that need to stay secure, observable and resilient even under national-scale load.
You’ll help build secure multi-cloud landing zones (majority AWS), GitOps-driven platforms and internal developer platforms that give engineers true self-service. You’ll modernise legacy estates into cloud-native architectures, unify observability across complex environments using OpenTelemetry and modern APM platforms, and drive FinOps-focused optimisation.
You’ll contribute to and help shape engineering standards, SRE-aligned operability, CI/CD performance, supply-chain security, platform-as-a-product thinking and event-driven automation. You’ll collaborate closely with client teams, bringing clear thinking and bold ideas to co-create modern platforms that make a real national-scale difference.
Your scope & influence as a Senior/Lead Platform Engineer
- Act as a senior technical voice across the engagement, influencing platform strategy, design choices and governance guardrails.
- Lead technical workshops and design reviews with client stakeholders and engineering teams.
- Set and evolve platform standards (security, reliability, operability, CI/CD, observability) and help teams adopt them in practice.
- Define SLOs, improve reliability, and lead incident reviews.
- Coach engineers through mentoring, pairing and pragmatic hands-on technical leadership.
- Bring platform-as-a-product thinking: golden paths, reusable capabilities and sustainable operations.
- Remain hands-on, by actively contributing to designs, code, reviews and problem-solving while leading and mentoring others.
What this looks like in practice
- Designing secure-by-default multi-account AWS landing zones (awareness of Azure/GCP patterns also relevant).
- Building internal developer platforms (IDPs) and self-service automation that boost developer experience.
- Deploying and operating hardened Kubernetes platforms (EKS/AKS).
- Creating unified observability stacks with OpenTelemetry, Prometheus and Grafana.
- Delivering cloud-native modernisation and transformation of legacy systems.
- Engineering high-quality CI/CD pipelines with DevSecOps & supply chain integrity.
- Implementing event-driven, automated infrastructure capabilities.
- Driving FinOps and cloud optimisation across complex estates.
- Applying platform-as-a-product thinking to create scalable, reusable capabilities.
- Providing hands-on technical skills & leadership and collaborating with client teams.
We like engineers who are curious, opinionated about good engineering and comfortable taking ownership of systems that need to work every time, at national scale.
If you want to solve hard problems, push modern engineering forward and deliver platforms that genuinely make a difference — you’ll fit right in.
