About Hexiosec

Hexiosec is a Cheltenham-based cyber security company founded and led by former government and defence security engineers. Our team has operated at the highest levels of national security, and we bring that expertise to everything we do.

Backed by significant investment, over the past two years we’ve invested heavily in developing world-class products, building a reputation for excellence and delivering solutions that outperform anything we’ve seen in the market. We are trusted by central UK Government and leading organisations across Education, Finance, Legal, Technology, and Healthcare. Our involvement in the National Cyber Security Centre’s Active Cyber Defence 2.0 programme and our role as Ambassadors for the Department for Science, Innovation and Technology’s Software Security Code of Practice underline our credibility and influence.

This is a rare chance to join a company with:

• World-class engineering talent and deep government security pedigree.
• Strong foundations and endorsements from top-tier government programmes.
• Proven success and early adoption by major organisations.
• Ready for successful scaling with fully productised offerings and ideal market conditions.

You’ll work alongside exceptional engineers and industry leaders, in an environment that values innovation, collaboration and impact.

Your Role

We are looking for talented individuals to help us accelerate growth. Roles will require initial time in our Cheltenham office to immerse yourself in our culture and products, with flexibility to move to one-three days per week minimum as your knowledge develops.
