We are Centrica! We’re so much more than an energy company. We’re a family of brands revolutionising a cleaner, greener future. Working here is #MoreThanACareer - we’re powered by purpose. Together we can make an impact that will truly change tomorrow. Whether you’re developing cutting-edge green tech, helping customers on the front line or simplifying operations behind the scenes.
Your work here isn’t just a job – it’s a mission. We all play a vital role in energising a greener, fairer future.
Centrica Energy is looking for a Senior Infrastructure Engineer, who will contribute to strengthening knowledge within the Active Directory and Core Windows Services field.
We are currently in the migration phase, where we want to consolidate Active Directories to simplify management and overall complexity of our setup. In the project you will be able to contribute with your knowledge in design aspects of Active Directory, involving structure, delegation, security aspects, but also hands on.
Many of our in-house developed applications leverage AD authentication in different ways, which adds to the complexity when consolidating and migrating them into a new domain, so application migration experience would be a big plus.
The daily long-term activities will include ensuring standardization, stability, and security around Active Directory, but also other Core Windows Components.

Several years of experience handling Windows Server Operating Systems: Knowledge of deployment and configuration, strong skills in troubleshooting, broad knowledge of other Windows Core Services like DNS, DHCP, file services and WSUS
Strong interest within automation and integration i.e. Powershell, Ansible, Terraform, SaltStack or IaC
Interest within security and hardening principles for all of the above, including Microsoft Security Baselines and CIS Framework
Personal skills:
Outgoing personality with an open mindset in terms of ideas and approach
Team player oriented – Good alone, but better together mentality
Able to structure your own work and work independently
Natural interest in standardization and documentation
Eager to learn and grow in your primary field of expertise
