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. - Work with the Platform team to harden our AWS environment across all accounts, and the other technologies that protect our cloud infrastructure, monitoring continuously for misconfiguration and drift. - Advise the Director of IT Ops on hardening and monitoring our corporate cloud infrastructure, with IT owning day-to-day operation. - Partner with the Director of IT Ops and our Platform team on our EDR platform, as our MDR provider, runs detection and response, and IT and Platform own deployment. Security ensures the configuration is right, including policies, exclusions and response settings, and that coverage across endpoints and servers has no gaps. - Stay highly threat-aware: understand Cognism's highest threats, and recommend and embed the controls that mitigate them, prioritising by real-world impact and exploitability rather than coverage. - Govern the patch management process for cloud workloads, containers and infrastructure, from scanning and risk-based prioritisation through to verified closure. - Review major architecture changes with Platform and Engineering, building guardrails into pipelines rather than relying on manual review of changes. - Partner with our Identity and Access Management expert, to govern the access model for our cloud and engineering systems: design how identity and authorisation work across the estate, with preventive guardrails that enforce least privilege by default. - Work with Data Engineering to ensure our data infrastructure is secure, covering how we ingest, process, access and surface data. - Partner with the Senior Application Security Engineer so that cloud, API and application controls reinforce each other. Logging, Detection, Response & SOC Partnership - Ensure all critical infrastructure is logged and monitored by our 24/7 SOC. Own log ingestion and logging configuration across cloud and application sources, so the SOC gets the right data with the right coverage, quality and retention. - Act as the main technical partner to the SOC: give them the business and environment context they need to tune detections and response, review alert quality with them, and keep improving how we detect, triage and respond together. --- Data: alder (https://alderhq.app).
