We’re a bunch of great people, working together, disrupting the utilities industry. Utility Warehouse is a truly unique FTSE 250 company. Our business model puts real social impact at its heart. We take the headache out of essential home services by bundling them all in one place. One provider, one account, one bill and lots of savings. Simple!

Technology at UW

Technology at UW

For our customers and partners, UW just needs to work; there when you need it, and invisible when you don’t – just like flicking a switch. Our proposition is simple to our customers but for our technology teams, the behind‑the‑scenes complexity is what makes it so interesting. Learn more about life in our Tech teams.

We work in small, fully autonomous teams that have real ownership of their products. We use the best tool for the job and constantly look for better.

We put people first. It’s all about you…

At UW, we prioritise not just what we deliver, but how and with whom we work. Our passion lies in tackling complex challenges alongside bright minds, recognising that true fulfilment comes from overcoming obstacles. By maintaining lightweight processes and fostering autonomy, we ensure swift delivery without compromising quality. Leadership at UW isn’t about lofty ideals but about getting hands dirty, providing guidance, and fostering a culture of support. We champion experimentation, shun egos, and value open discourse, collaboration, and continual learning.

We are looking for someone who will be responsible for the ongoing deployment, maintenance, and support of our Windows VMware and storage infrastructure.

We work together. Your team and the people you will work with…

The BTG Workplace Technology Team is responsible for managing and supporting UW’s storage infrastructure. Their primary focus is project‑based work, including deploying new storage solutions to enhance system performance and capacity. Additionally, they conduct regular maintenance tasks, such as applying security patches to ensure system integrity and protection.

Beyond project and maintenance work, the team handles fourth‑line support escalations from the EUX team, addressing complex technical issues that require advanced troubleshooting. They also actively monitor and support the infrastructure, ensuring optimal performance and stability for the storage systems.

We deliver progress. What you’ll do and how you will make an impact.

As a Senior Infrastructure Engineer, your goal is to:

• Own and complete large projects in your domain with minimal guidance.
• Be involved in setting team goals and owning their delivery.
• Understanding the value of committing to company and team objectives and managing the teams focus around these (no bikeshedding).
• Be the primary technical owner and subject matter expert for all systems in Workplace infrastructure.
• Design and implement solutions in keeping with our design ethos to solve our complex problems and help the business scale and grow.
• Propose and review designs and RFCs.
• Proactively remove roadblocks for you and your team.
• Ensure that there is always a high quality of delivery.
• Actively reduce complexity and tech debt in our systems and operations.
• Actively mentor, coach, and be involved in the onboarding of new members into the team.
• Always look to improve the culture and inclusivity of our team.
• Look for opportunities for the team to expand and grow by getting involved in projects and work in other areas of the business.

Technically what you’ll be expected to do:

• Manage, troubleshoot and deploy infrastructure, specifically focused on the Windows environment but extending to network, product and cloud systems.
• Act as a subject matter expert for technical troubleshooting across our managed systems.
• Assist with incident response and post‑incident analysis for the broader operations domain.
• Design and develop automation strategies for ongoing system management and administration, including the use of appropriate automation and configuration management tools.
• Manage and support both on‑premise and cloud environments within a technology operations team.
• Utilise and maintain monitoring, alerting, and service desk systems, following established processes and creating documentation where needed.
• Troubleshoot and resolve technical operational issues across Active Directory, Windows, Linux, and networks, with a primary focus on Windows while leveraging knowledge of Linux.
• Apply a working knowledge of infrastructure as code and automated provisioning & configuration management using tools like Microsoft DSC, Terraform, and Ansible.
• Strengthen and maintain Active Directory security.
• Deploy, maintain, and optimise Microsoft RDS for performance and reliability (A must!).
• Manage and configure SCCM and/or Intune for system administration and endpoint management.
• Deploy, operate, and maintain legacy MS SQL Server, MS‑SQL databases, and related services, including stored procedures, SSRS, SSIS, and DTSx.
• Administer and support virtualisation and containerisation technologies such as Proxmox, VMWare and Docker.
• Work effectively in a remote environment or collaborate with distributed teams.
• Develop and maintain PowerShell/DSC scripts for production use, ensuring reliability and efficiency.
• Experience in deploying NETAPP filers in multi‑site environments, configuring and maintaining cross‑site replication.

Your skills & experience

We make use of a number of tools and approaches, but most frequently:

• Autonomous teams making use of common platforms for product development
• Github, with a strong leaning towards supporting (and release) of open source projects
• Microsoft DSC
• Kubernetes & Docker
• Terraform & Ansible
• Proxmox, VMWare ESXi/vSAN, Netapp Filers
• Linux in on‑premise clusters and in Cloud (AWS/GCP)
