Job description
From Parser’s job post, as they wrote it.
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.
Read the full description
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.
Technology Stack (Main Technologies):
* Azure Core: Multi-subscription landing zones, hub-and-spoke networking, Entra ID, Azure Policy, Private Link, Key Vault, Azure RBAC. (MUST)
* AKS Platform Architecture: Building strict multi-tenant environments, logical isolation (namespaces/RBAC), network policies, resource quotas, upgrade strategies, node pools, and workload identity. (MUST)
* Advanced Kubernetes Ecosystem: Deep understanding of control plane mechanics, custom resource definitions (CRDs), and operators. (MUST)
* IaC: Terraform / Open Tofu module design. (MUST)
* Kubernetes Engineering: GitOps (Argo CD/Flux), secrets management, ingress/mesh, and OPA/Gatekeeper. (MUST)
* Observability: OpenTelemetry (MUST)
* Tooling: Spacelift, Atlantis, or Terraform Cloud (Desired)
* Governance: EPAC (Enterprise Policy as Code) (Desired)
What You'll Bring To Us:
* Recent, hands-on experience operating multi-cluster AKS in production environments, either multi-region or multi-tenant.
* Proven experience building and architecting complex Kubernetes platforms from scratch.
* Experience with Kubernetes platform engineering, including ingress and service mesh, OPA / Gatekeeper policy, secrets management, and progressive delivery.
* Strong security awareness, displaying comfort with CAF / ALZ patterns, least-privilege IAM, network segmentation, and policy-as-code.
* Experience working with regulated or financial services workloads on Azure.
* FinOps instincts for managing AKS and networking costs effectively.
What We'll Offer You In Return:
* The chance to join an organization with triple-digit growth that is changing the paradigm of how software products are built.
* The opportunity to form part of an amazing, multicultural community of tech experts.
* A highly competitive compensation package.
* A flexible working environment.
* Medical insurance.
