Lead DevOps Engineer

Lead DevOps Engineer | Azure, .NET, Kubernetes / Docker | Build the Future of PropTech

Our client, the UK's largest property services group, is on a transformative mission to modernise their platforms, drive innovation through automation, and become a tech-first leader in the real estate space. Backed by a major financial institution and with a brand-new, tech-committed CEO at the helm, this is a rare opportunity to lead platform reliability across a business that touches millions.

This is not just a hands-on role, it’s a leadership opportunity at the centre of a £multi-million transformation programme. You’ll shape and grow a Site Reliability function from the ground up, beginning with owning the Azure-based App Platform and evolving it into a modern, scalable engineering hub for over 400 IT professionals and 100 software engineers.

Our client defines this role as ‘site reliability engineering’ but is understanding and open to you coming from a DevOps, Platform, and Cloud background as these roles can be synonymous and have the same duties.

Tech You’ll Use:

• C# / .NET Core – It is absolutely essential you have strong skills here, either coming from a development background or having gained strong C# .NET skills and experience
• Azure cloud environment (end-to-end responsibility)
• Terraform, BICEP, or ARM templates
• Docker & Kubernetes for container orchestration
• Azure DevOps, GitHub Actions, Jenkins

Why This Role?

• Lead the function technically as well as being the lead of a future team (up to 10 headcount over time) that you will help hire, develop and manage.
• Set the culture, tooling, and technical standards for operational reliability.
• Act as both a hands-on technical lead and strategic voice in cloud reliability and automation.
• Be part of a huge digital upgrade initiative across infrastructure, applications, and data platforms.
• Whilst this is a lead role, you do not need to have had a previous leadership or management position. You will however have to have the gravitas, hunger and ability to lead and grow an SRE team.

What You’ll Do:

• Own the operational reliability of a large-scale Azure cloud platform.
• Drive automation-first culture using Terraform, Azure CLI, PowerShell and more.
• Lead incident management, capacity planning, and performance-tuning initiatives.
• Guide engineers in observability, cost optimisation, and security best practices.
• Define and track service level objectives (SLOs) to improve engineering outcomes.
• Champion a DevOps mindset with “you build it, you run it” accountability.

We’re Looking For:

• Proven background in Site Reliability Engineering or senior DevOps roles.
• Strong software engineering fundamentals (especially in .NET/C#)
• Confidence in leading incident response, platform scaling, and service design.
• Someone who thrives in a matrixed, multidisciplinary structure and enjoys mentoring others.

The Offer:

• £80–85k base salary
• 1 day per week in a stunning lakeside office
• 25 days holiday + bank holidays
• 5% employer pension contribution
• Private medical care, Aviva GP access for family, subsidised lunch & free gym
• Free parking and shuttle bus from Milton Keynes train station if required
