Senior Platform Engineer - Automation and Security

Senior Platform Engineer – Linux/Tooling/Security

Our world-leading Time & Frequency department are seeking a Senior Platform Engineer specialising in Microsoft infrastructure and Linux system administration.

This is an exceptional opportunity to join the global authority in precision timing at a defining moment for UK digital infrastructure. 

Backed by a government investment of £180 million in the National Timing Centre (NTC) programme, we are developing a world-first resilient time distribution capability that will provide industry with a robust complement to satellite systems (such as GPS) – which are increasingly vulnerable to disruption from solar storms, jamming and spoofing. This will underpin essential services, including

• Telecommunications, 
• Online banking, 
• Emergency response, 
• Transport networks, and 
• Wider digital and data-driven operations.

Together, these services form the backbone of modern society - and your leadership will help ensure they remain secure, reliable and robust even if global navigation satellite systems fail.
