Who we are

Ilkari is a privately-held start-up based in Dublin, Ireland. We deliver hyper-private scale innovation and technology to safeguard and secure data, enabling true data sovereignty even as the pace of change accelerates. Our best-in-breed sovereign technology delivers privacy and control over where companies’ data resides, where it flows, and how it’s accessed.

We’re here to rewrite the story of data sovereignty – empowering innovators, pioneers and visionaries to make their mark. We believe the sky is not the limit. We strive for the perfect balance of simplicity and excellence in everything we do, and we’re looking for people who are ready to join our journey and rewrite the story of data sovereignty.

Role overview

We’re looking for a Senior Platform Engineer to join our Engineering team and take a lead role in building and operating the infrastructure that underpins our products and services. You’ll focus on delivering secure, reliable, and scalable platforms, with a strong emphasis on OpenStack, to support our sovereign cloud strategy and meet customer expectations.

This role is critical to supporting our business goals — enabling faster delivery of features, improving system uptime, and reducing operational risk. You’ll be responsible for designing, automating, and optimising our platform stacks, while working closely with engineering, product, and operations teams to reduce technical debt, improve maintainability, and ensure our infrastructure is ready to scale with the business

New to OpenStack? No problem. If your Linux, Automation, and other required skills and expertise are strong and you’re eager to learn, we’ll help you get production-ready.

What you'll do

• Own platform reliability for OpenStack, Proxmox, and Kubernetes, define SLOs, manage performance, security, and resilience.

• Drive adoption of Infrastructure-as-Code (Terraform, Ansible) and GitOps across provisioning and operations.

• Own Kubernetes end-to-end on bare metal, OpenStack, and Proxmox: cluster build/upgrade, day-2 ops, backup/restore, and multi-cluster management.

• Lead observability for the platforms, logging, metrics, traces, alerting and tune systems for performance and signal-to-noise.

• Evaluate, standardise, and lifecycle platform components (patching, upgrades, compatibility) to meet performance, compliance, and availability standards.

• Capacity management, right-size compute/storage/network, plan headroom, forecast demand, and optimise utilisation.

• Run architectural reviews, lead incident response and post-mortems, and drive continuous reliability improvements.

• Create and maintain clear documentation - runbooks, diagrams, standards and deliver internal training/mentoring to scale good operations.

• Participate in and potentially lead the on-call escalation process for critical incidents.
