We're recruiting for a contract Senior Cyber Security Engineer to join the IT security function of a leading global financial services organisation in London. It's a hands-on SME role covering banking and securities technology across EMEA, with a focus on security validation, automated penetration testing, breach and attack simulation and vulnerability remediation.

• Running and optimising automated penetration testing, breach and attack simulation, threat emulation and cyber deception platforms
• Analysing vulnerabilities and assessment findings, then driving risk-based remediation, retesting and validation with engineering teams
• Operating security tooling across network, endpoint, email, web, edge and cloud, from onboarding and tuning to upgrades and refresh
• Investigating incidents and complex technical issues, finding root causes and deploying security changes through change governance
• Supporting internal audit, IT risk and governance teams against frameworks such as ISO 27001, SWIFT CSCF and NIST
• Building automation, dashboards and integrations that reduce manual work, and keeping documentation audit-ready

What You'll Bring

• 8+ years in cyber security or information security, with hands-on enterprise security tooling experience
• Experience with security validation, automated penetration testing, breach and attack simulation or exposure management platforms
• Strong technical grounding in Windows Server, Linux, networking, Active Directory, DNS and GPO
• Vulnerability management and remediation assurance experience across on-premises, cloud or hybrid environments
• Confidence working with audit, risk and compliance stakeholders

Desirable: Python, Ansible or PowerShell scripting, Azure or AWS, VMware, ServiceNow, Zero Trust architectures, cyber deception or honeypot technologies, CISSP, Security+, CEH or GCIA
