Senior Dev Ops / Platform Engineer

Location :
Hybrid – Oxford (2 days per week)

Salary : £140,000–£240,000 + Excellent Benefits

Are you passionate about building and operating highly reliable, scalable infrastructure at scale? We’re partnering with a cutting‑edge science and technology organisation to find a Senior Dev Ops / Platform Engineer who will take ownership of the core platforms that power mission‑critical workloads across the business.

This role is ideal for a senior Dev Ops engineer who thrives on automation, performance optimisation, and operating complex systems in demanding environments.

You’ll join a high‑impact platform engineering team responsible for designing, securing, and operating large‑scale compute and data platforms. Working closely with engineers and researchers, you’ll enable teams to move faster through robust Dev Ops practices, modern infrastructure tooling, and strong operational foundations.

This is a hands‑on role with real influence over architecture, tooling, and standards across the organisation.

• Design, build, and operate highly available, scalable infrastructure platforms supporting compute‑intensive workloads.
• Automate infrastructure provisioning and configuration using Infrastructure as Code (IaC).
• Build and maintain Kubernetes‑based platforms for containerised workloads.
• Develop and improve CI / CD pipelines to support rapid, reliable deployments.
• Implement observability, monitoring, alerting, and incident response best practices.
• Optimise performance across compute, storage, and networking layers.
• Embed security, resilience, and compliance controls into platform design (“Dev Sec Ops ”).
• Partner with internal teams to forecast capacity, improve reliability, and streamline delivery workflows.

• Dev Ops & Platform:
  Kubernetes, Docker, Terraform, Argo CD, CI / CD pipelines
• Cloud & Infrastructure: AWS, Azure, GCP (cloud‑agnostic mindset)
• Compute & Storage: GPU‑enabled infrastructure, high‑performance storage systems, high‑speed networking
• Observability:
  Monitoring, logging, and alerting tools across distributed systems

• Extensive experience in Dev Ops or platform engineering roles operating production systems at scale.
• Strong expertise with Kubernetes, containers, and Infrastructure as Code.
• Experience building reliable CI / CD pipelines and automation‑first platforms.
• Deep understanding of Linux, networking, and distributed systems.
• Comfortable working autonomously in complex, fast‑moving environments.
• Experience with GPU or high‑performance compute environments is a strong plus (but not essential).

• Work on technically challenging platforms with real‑world impact.
• Influence architecture and tooling decisions at a senior level.
• Join a collaborative, high‑calibre engineering culture.
• Competitive compensation and excellent benefits, including private medical insurance, enhanced holiday, and pension.
