Platform Principal Engineer
This position allows you to join a fast-growing technology organisation focused on the critical migration and architectural evolution of our.NET services from AWS to Azure. If you are passionate about cloud-native transformation and want to lead the shift toward asynchronous, high-scale architectures, this opportunity is for you.
Role Summary
As an Azure Principal Platform Engineer, you will act as the authoritative Subject Matter Expert (SME) to help a major fintech architect, bootstrap, and build from scratch an enterprise-grade, multi-tenant AKS platform on a greenfield Azure landing zone. Crucially, you will guide the establishment of an internal platform team, designing the platform operating model and upskilling in-house engineers along the way. You will also collaborate to upskill the in-house team along the way.
The Impact You'll Make:
- Architect and Bootstrap: Design and provision a greenfield, highly-scalable, multi-tenant AKS platform from the ground up (focusing on underlying cluster architecture, not just workload deployment).
- Act as the Kubernetes Reference (SME): Serve as the authoritative internal expert for the vast Kubernetes ecosystem, filling a critical knowledge gap and guiding our long-term architectural direction.
- Establish a Platform Operating Model: Help structure and establish an Internal Developer Platform (IDP), defining how the new platform team will interact with and empower developer teams through self-service capabilities.
- Upskill and Mentor: Transition the in-house engineering team into a high-performing internal platform team throughout the platform build process.
- Observability: Design and implement enterprise-grade logging, metrics, and tracing for Kubernetes at scale.
- IaC Leadership: Implement and manage Infrastructure as Code to a senior standard, taking charge of state strategy, module design, and drift management.
