OT Cybersecurity Engineer, Global in London

Vantage Data Centers powers, cools, protects and connects the technology of the world’s well-known hyperscalers, cloud providers and large enterprises. Developing and operating across North America, EMEA and Asia Pacific, Vantage has evolved data center design in innovative ways to deliver dramatic gains in reliability, efficiency and sustainability in flexible environments that can scale as quickly as the market demands.

The Vantage Cybersecurity Department is very hands-on. In most cases, we specify, purchase, configure, and maintain all networking and server hardware with a keen focus on cybersecurity measures. We also work closely with partner Value Added Resellers (VARs) to learn about the latest technological changes and cybersecurity trends so that we can make informed purchase decisions. We are always looking for ways to strike the best balance between technology, performance, cost, and cybersecurity. Vantage Cybersecurity Department also participates in designing each of our new data center building’s cybersecurity infrastructure. If you like getting your hands dirty and helping to design, build, and maintain cybersecurity infrastructure in a modern data center, then come work at Vantage. We’re expanding with many new builds, enhancing our focus on safeguarding data and infrastructure in the face of evolving cyber threats.
