Functional Consultant jobs in United Kingdom

THE ROLE

This role is all about building and scaling the physical foundation of Form3's infrastructure - true bare metal. It's a hands-on engineering position for someone who thrives at the intersection of hardware and software.

As a Platform Engineer, you'll take ownership of managing and scaling high-performance bare metal systems. You'll work deeply with server hardware, oversee firmware updates, and build automation around server provisioning. The focus is on developing and maintaining resilient, scalable distributed systems that support our broader platform - ensuring optimal performance, reliability, and operability.

Projects you'll be involved with:

• Streamlining our approach to data centre maintenance to make it as low effort as possible
• Scaling out the UK data centres to meet future customer demand
• Improving performance of our infrastructure
• Improving the automation of infrastructure provisioning

WE'RE LOOKING FOR

• Solid grounding in system installation, including operating system installations, building system images, and automated server provisioning
• Experience in Infrastructure as Code patterns and practices (Terraform and Ansible are a plus)
• Familiarity with hardware lifecycle, including firmware patching, BIOS configuration, and component troubleshooting
• Knowledge of networking, including Layer 2 and Layer 3 protocols, VLANs, and link aggregation
• Strong understanding of virtualization technologies like KVM and QEMU and their interaction with underlying hardware
• Understanding of Kubernetes and its intricacies when run on bare metal infrastructure (ideally)
• Experience running Kubernetes in cloud environments is a real plus
• A background in Software Engineering and solid programming experience is beneficial but not essential (preferably Go but we're flexible on this)
• Enthusiasm towards ensuring a high degree of service reliability, always putting the stability & safety of our products at the forefront
