Job description

Senior Manager, Service Reliability & Managed Services | Kubernetes, Managed Services, Team Leadership | Global Software Company

• Salary: €130,000 - €150,000 + bonus (typically 25%)
• Location: Dublin, 4 days a week on site

Our client is a global software company whose products run behind mission‑critical systems in heavily regulated industries. This role is the senior SRE and platform operations leadership seat for their managed services, where youll run the estate as it moves onto a new, cloud‑agnostic Kubernetes platform. Its people leadership, not day‑to‑day coding: youll lead three globally distributed functions, operations and reliability, security and compliance, and customer experience.

Youd be the right hand to the Global Delivery Lead, leading a team of around 15 to 20. Yous own the reliability targets, chair the Severity 1 incident calls, and represent the business when customers elevate. The wider operation is scaling hard, so youre building it as much as running it.

Non‑Negotiables

• 10+ years SRE or cloud operations background
• People leadership across globally distributed teams
• Incident command, leading Severity 1 response
• Managed services reliability and availability at scale
• Regulated environments with real compliance and audit demands
• Customer escalations at executive level

What Yous Work With

• Kubernetes, greenfield and cloud‑agnostic
• Multi‑cloud across AWS, Azure and GCP plus private data centres
• GitOps CI/CD and Infrastructure as Code (IaC)
• Fleet orchestration at scale
• Observability, backup, disaster recovery and failover
• Security across identity, access controls and vulnerability management
• Customer portal and API layer for self‑service tenancy and billing

Nice to Haves

• Compliance frameworks like SOC 2 or ISO 27001
• SaaS or multi‑cloud managed services
• Budget ownership over tooling and contractor spend
• Scaling a team through rapid headcount growth

Why Join / Projects

This is a rare build‑and‑run job. The Kubernetes platform is greenfield, nothing in production yet, and it is designed to be completely cloud and data‑centre agnostic. Product ships one container and it runs anywhere, on any public cloud or in the companys own data centres, with upgrades, patching, resilience, failover and disaster recovery all handled at the platform level and invisible to the customer. Yous own the operation that keeps all of that reliable as it scales very wide, very fast.

As the Global Delivery Lead’s right hand, youll run three functions and a team of around 15 to 20, with real budget authority over tooling and contractors. The operation is growing fast, so youll shape how its hired, built and structured from the ground up. The roadmap is ambitious, with major new products moving onto the new estate over the next couple of years.
