WHO ARE WE Cognism is the leading provider of European B2B data and sales intelligence. Ambitious businesses of every size use our platform to discover, connect, and engage with qualified decision-makers faster and close more deals. Headquartered in London with global offices, Cognism’s contact data and contextual signals are trusted by thousands of revenue teams to eliminate the guesswork from prospecting. The Senior Cloud Security Engineer owns the defence and detection of Cognism's cloud environment, reporting to the Director, Security Engineering & Operations. As the senior technical voice on cloud security, you will lead on the development of our cloud security roadmap, and support and mentor the other cloud security engineers on the team. AWS is at the core, but the estate also spans SaaS and managed services: source control, edge and networking, databases, data streaming and messaging, and secure access. As we move from software to infrastructure that customers and their AI agents depend on, our attack surface grows: more APIs, an MCP connector, and data pipelines feeding our proprietary data engine. You will be the engineer who knows which threats matter most to Cognism's cloud infrastructure, and who builds the controls, detections and automation that stop them. This is a hands-on, blue-team role where automation is the default and AI is a force multiplier . You would rather write the code that closes a gap than raise a ticket about it, and you use AI wherever it genuinely speeds up triage, detection engineering, investigation or remediation. You will work closely with Platform, Data Engineering, IT and our 24/7 SOC partner, as a partner to engineering, not a gatekeeper. WHAT YOU'LL OWN Cloud Security Roadmap & Controls Lead our cloud security roadmap: assess where we are exposed, recommend priorities by threat and business impact, agree the plan with the Director and Engineering leaders, and execute or support on delivery.
