What are we looking for?
We're looking for a Principal Infrastructure Engineer to join the IT Operations team. You'll be the senior technical voice across infrastructure, Azure cloud, identity, and platform services.
What is the IT Operations & Engineering team?
The team designs, builds and runs the platforms the whole business depends on, across on-premises and Azure. It's a hands-on team in a regulated environment, partway through moving to an automation-first, platform-led way of working. This role leads that shift.
Here’s how you’ll contribute to the team:
- Be the senior technical authority and final escalation point across infrastructure, cloud, identity and platform services.
- Deputise for the IT Manager and help set the team’s technical direction.
- Drive the design, resilience and continuous improvement of on-prem and Azure platforms.
- Lead root cause analysis on complex issues and major incidents, and make sure the fixes stick.
- Shape engineering standards, architecture decisions and platform best practice.
- Build automation, Infrastructure as Code and reusable platform capabilities the team can build on.
- Hold third-party suppliers to a high technical bar.
- Mentor engineers and champion secure, resilient, automate-it-first habits.
This role will give you the opportunity to:
- Own the technical direction. This isn't a ticket queue. You'll set the standards, and others will build to them.
- Modernise a real enterprise estate. It's hybrid, regulated and business-critical, which means the engineering problems are genuinely interesting.
- Lead without leaving the keyboard. You'll stay hands-on while shaping how the wider team works.
- See your work matter. The platforms you run help pay pensions to hundreds of thousands of people.
Desirable skills and experience
- Extensive experience in Infrastructure, Systems or Platform Engineering within a complex enterprise environment.
- Strong Azure expertise and a good grasp of modern cloud technologies.
- Advanced automation and IaC skills: Terraform, PowerShell and Ansible.
- Deep knowledge of Active Directory and Microsoft Entra ID.
- A solid understanding of platform engineering, CI/CD and observability.
- Broad infrastructure knowledge across Windows, Linux, networking and enterprise platforms.
- A track record of influencing technical direction and engineering standards.
- Financial services or other regulated-environment experience would be a great plus.
Here are some of the technologies in the estate. It's not an exhaustive list, and nobody expects you to know everything, but it gives a flavour:
- Endpoint: Intune, SCCM
- Virtualisation: hypervisor and hyperconverged infrastructure
About you
- You're the person others go to when something's properly broken.
- If you've done something twice, you automate it the third time.
- You build for resilience and security by design, not as an afterthought.
- You're comfortable pushing back on suppliers and making the case for the right technical decision.
- You enjoy bringing other engineers up with you.
- You can explain complex technical problems clearly to engineers and non-technical stakeholders alike.
