Senior Platform Engineer: Infra, CI/CD & Hybrid Cloud

Olix Computing; Greater London; On-site; GBP 80,000 - 120,000; Full time

Job summary

OLIX is expanding and seeks a senior infrastructure engineer to own the internal platform our engineering teams build, test, and collaborate on, spanning compute, storage, networking, build and CI/CD systems, and security. You’ll turn slow workflows into fast, secure ones with hands-on ownership.

Join a high‑ownership role where you define how internal infrastructure, security, and IT work here, partnering with hardware and ML teams to accelerate engineering velocity and reliability.

Qualifications

• 5+ years in infrastructure, platform, or DevOps/SRE engineering, with a track record of owning systems end to end.
• Strong infrastructure‑as‑code and automation skills: Terraform, Ansible, and scripting in Python and Bash.
• Experience operating across hybrid cloud and on‑prem/bare‑metal environments.
• Strong grasp of infrastructure security: IAM, secrets management, network security, and hardening across cloud and self‑hosted systems.
• Excellent problem‑solving skills, with the ability to diagnose and resolve complex, cross‑layer issues in a fast‑moving environment.
• A collaborative communicator who can work with hardware and ML engineers and explain infrastructure trade‑offs clearly.

Responsibilities

• Build and operate the platform: design, provision, and run the Kubernetes and bare‑metal infrastructure that powers development, simulation, and testing workloads.
• Automate everything: own infrastructure‑as‑code (Terraform) and provisioning pipelines so environments are reproducible, version‑controlled, and fast to stand up or tear down.
• Improve the developer platform: build and maintain CI/CD, internal tooling, and self‑service workflows that let hardware, software, and compiler engineers ship without waiting on you.
• Tune for performance: optimise networking and storage for throughput and latency that ML and hardware workloads require.
• Own reliability and observability: implement monitoring, alerting, and capacity planning, and drive availability and performance across hybrid cloud and on‑prem environments.
• Own platform security: implement identity and access management, secrets management, data protection, and threat detection across self‑hosted and cloud infrastructure.
• Drive continuous improvement: proactively find and fix bottlenecks, manual steps, and reliability gaps that slow the wider engineering team down.
