Radiant is looking for a Principal Infrastructure Engineer to lead the design and implementation of its AI‑native cloud platform. Based in the UK with occasional office travel, you will shape scalable, resilient infrastructure that powers high‑performance computing and AI/ML workloads across a global environment.

Key responsibilities

  • Architect and implement virtualisation solutions optimised for AI‑native and HPC workloads, including hypervisor tuning and dynamic storage/network provisioning.
  • Lead bare‑metal lifecycle management, provisioning, orchestration and optimisation of Unix/Linux systems at scale.
  • Design and deploy high‑performance, cloud‑native storage and networking, leveraging SDN, BGP and advanced protocols.
  • Build and operate Kubernetes clusters across hybrid and multi‑cloud environments, including CNI, service mesh, security hardening and CI/CD pipelines.
  • Develop automation frameworks using Terraform, Ansible, Go and Python to reduce operational toil and ensure reliable global operations.

Required profile

  • Proven experience in infrastructure architecture and large‑scale global deployments, especially in AI‑native, HPC or cloud‑native contexts.
  • Demonstrated ability to evaluate and adopt new tooling and technologies.
  • Strong communication skills and experience mentoring technical teams.

Required skills

  • Kubernetes, CNI, service mesh, RBAC, OPA/Gatekeeper, Kyverno
  • Terraform, Ansible, Go, Python
  • Unix/Linux systems, hypervisor technologies
  • Networking protocols (TCP, UDP, DNS, BGP) and SDN
  • Observability tools (Prometheus, Grafana) and distributed tracing
  • Secrets management (Vault, OpenBao) and supply‑chain security (cosign, sigstore)

What we offer

  • Opportunity to work on a rapidly scaling AI infrastructure business at the forefront of the industry.
  • Broad exposure to a cutting‑edge physical and software infrastructure stack.
  • Supportive, Brookfield‑backed environment with mentorship and growth opportunities.
