Senior Linux Engineer

Senior Linux Engineer | Linux, Kubernetes, GPUs, Bare-Metal Systems | Biotech Scaleup

Join a groundbreaking biotech scale-up working at the frontier of biological data mapping and commercialising protein systems discovered in some of the most extreme environments on Earth. Their technology has applications from cold-wash laundry pods to next-gen therapeutics, and they’re growing fast.

The tech team sits at the interface of biology and compute: they’ve got 45 people globally (30 in the UK in a cool office in Farringdon), with 18 in tech and a lean but powerful Platform Engineering function of 3. You’ll be stepping into a hands-on senior role to support, scale and maintain their Linux Server, and GPU-rich on-premise infrastructure. All orchestrated by Kubernetes, Terraform and Ansible.

Essential experience:

• Linux (Ubuntu) systems background
• Strong Kubernetes experience, ideally at a CKA level understanding of clusters, nodes, and resources
• Experience working with on-prem or hybrid infrastructure, and an understanding of GPU compute is very beneficial
• Scripting in Python or Go,
• Terraform or Ansible or other leading IaC experience
• Comfortable with multiple cloud concepts but not reliant on cloud-native tooling (AWS/Azure only used for backup, redundancy and global access)
• Hands-on, pragmatic, and excited about enabling research that pushes the boundaries of biology

What you'll be doing:

• Managing and scaling a 95% on-prem estate (50 physical servers, including some powerful nodes with H200 NVIDIA Hopper GPUs)
• Building and operating Kubernetes clusters on bare metal (no virtualisation)
• Using tools like NVIDIA Base Command Manager to maximise compute efficiency
• Supporting internal users with deployment, monitoring and performance tuning
• Automating infrastructure with Terraform and Ansible
• Collaborating closely with the scientific, data and engineering teams to integrate new workloads

Why this is cool:

• You'll work with real scientists and explorers, and the data comes from ice caps, volcanic springs, and deep-sea vents
• It’s deep-tech for a reason: every system you build supports real-world biological discovery
• Tech decisions are pragmatic and performance-driven, with no red tape and no compliance bureaucracy

The offer:

• Share options
• Private health insurance (AXA)
• Generous holiday; 5.7 weeks holiday, Christmas shutdown, your birthday day off
• Ongoing development budget
• Hybrid working (most people do 3-4 days in the London office, with flexibility)
