Senior Engineer (Platform Engineering)

Platform Engineer Reading – Hybrid (3 days onsite, some flex possible) £65,000–£75,000 + Bonus + Benefits We’re looking for a Platform Engineer with a strong Linux/on-prem background to join a growing Platform Systems team supporting large-scale ISP and operational infrastructure environments. The current environment is predominantly Linux and on-prem focused, with a major programme underway to modernise infrastructure, expand cloud capability, and mature platform engineering practices across the team. You’ll play a key role in helping shape this journey. This role would suit someone with a strong Linux infrastructure and virtualisation background who has moved into cloud and automation engineering over the last few years, particularly within ISP, hosting, or large-scale application environments. This is a hands-on senior engineering role with opportunities to mentor others, influence best practices, and contribute to the team’s evolution into a more modern platform engineering function. What We’re Looking For We’re looking for engineers with a strong infrastructure and Linux engineering foundation, rather than candidates coming purely from cloud-native environments. Experience in the following areas would be valuable: Strong Linux systems engineering / platform engineering experience Experience within on-prem and virtualised environments Exposure to VMware, KVM, Proxmox, Nutanix or similar virtualisation technologies AWS engineering experience, particularly hybrid cloud/on-prem integration Automation and configuration management tooling (Ansible, Puppet, Chef, Terraform) Scripting or development experience using Python, Go, or Perl Understanding of platform resilience, monitoring, and operational best practices Experience mentoring, supporting, or guiding other engineers Backgrounds in ISP, hosting, web hosting, or application hosting environments would be particularly relevant. The Team & Opportunity The team is currently evolving from a traditional systems engineering function into a broader platform engineering capability, with a strong roadmap of projects planned over the next 12–24 months. This is an opportunity to join at a key stage of that transformation, with the ability to influence engineering direction, modernisation initiatives, and cloud adoption across the business.
