DevOps Engineer

Helical Levity is led by world renowned cyber security expert James Lyne and combines a team of passionate and talented designers, developers and security researchers. Together we design and build industry leading tools that, amongst other things, help to identify and develop new cyber security talent. Our key product, CyberStart, is a suite of tools which support three major programmes in the UK and US:

The product, built mainly for young adults, is an engaging cyber security game where students take on the role of an agent in the cyber protection agency and get to hack, forensicate and code break their way through levels filled with a rich narrative, immersive design and realistic security labs. The product has been used by over 200k young adults, but we're still only at the beginning of an exciting roadmap we'll be working through over the next couple of years.

Much of the team work remotely but we do have an office in Ascott-under-Wychwood. There is the option to work in either environment but we do tend to meet up in Ascott-under-Wychwood or London to catch up on projects on a fairly regular basis, so being within a sensible travel distance of either would be useful.
