About the Company
Our client is a next-generation cloud security platform using runtime context and eBPF-powered sensor technology to identify and prioritise critical risks across cloud environments. Their platform spans agentless cloud posture discovery, real-time threat protection, and integrated API security... delivering comprehensive, cost-effective protection from misconfigurations to active malware defence. Backed by strong credentials and growing quickly, they are building out their UK presence and bringing deep security expertise closer to their European customer base.
The Role
This is a high-ownership, senior-level position joining an established MDR team as the founding UK member of the security organisation. You will own UK-hours coverage independently, lead complex security investigations, and act as the senior escalation point for critical incidents... all while working directly with customers to translate findings into clear, actionable guidance. The role carries real weight from day one and is structured with a clear path toward technical or team leadership as the UK function scales. It suits someone who is genuinely passionate about cloud security, comfortable operating with autonomy in a fast-paced startup environment, and confident engaging directly with customers under pressure.
