Senior Platform Engineer

Our client is a well-established financial services organisation with a significant engineering presence in Ireland. They are expanding their Platform & Infrastructure Engineering team and looking for a Senior Platform Engineer to help shape and own the shared services that the wider engineering organisation depends on.

The Role

This is a platform engineering role, not DevOps. Application teams own their own pipelines; your focus is the paved roads they run on — the multi-tenant Kubernetes platform, internal developer platform (IDP), cloud networking, identity, and policy-as-code.

You will own major platform initiatives from brief to production, set technical standards, mentor junior and mid-level engineers, and partner with architecture and security on cross-cutting decisions.

IaC-first culture. If your instinct is to click through a console, this role is not for you.

Key Responsibilities

• Design and evolve a multi-tenant AKS platform: tenancy model, upgrade strategy, operator ecosystem, service mesh
• Build and maintain services for the internal platform catalog
• Architect Terraform module hierarchies and set IaC standards for the team
• Contribute to zero-trust networking, cloud identity, and policy-as-code
• Mentor engineers and raise the technical bar through reviews and pairing
• Lead incident response for platform systems and contribute to the on-call rota

Essential Skills

• Deep production experience on a major public cloud (Azure preferred; AWS or GCP considered)
• Designed and operated multi-tenant Kubernetes platforms at scale
• Terraform is your primary tool — you design module hierarchies, not just write modules
• Fluent in Python for platform tooling; you treat platform code as software
• Strong cloud networking: hub-and-spoke, peering, Private Link, egress controls
• GitOps mindset; production experience with ArgoCD or equivalent
• Hands-on with policy tooling: Kyverno, OPA, or equivalent
• Comfortable in regulated environments (PCI-DSS, ISO 27001)
• Strong communicator; writes architectural documents that become team references

Nice to Have

• CKA or CKS certification
• Azure, AWS, or GCP certifications
• Experience with secrets management (Vault, cloud-native KMS)
• Familiarity with eBPF / Cilium
• Financial services or regulated industry background

Package & Location

• Salary up to €110,000 depending on experience
• Hybrid working — primarily remote with occasional travel to the Kerry office
• Permanent role, based in Ireland
