Enterprise Security Posture Management SME

Join our Proactive Defence team as an Enterprise Security Posture Management SME, leading capabilities across Attack Surface Management (ASM), Attack Path Management (APM), and Breach & Attack Simulation (BAS) within the CISO organization. You will drive a proactive, threat-informed approach to exposure management, helping the bank identify, prioritise, and reduce exploitable security risk through greater visibility, attack path analysis, and continuous control validation.

This role is critical to shifting from reactive vulnerability management to proactive exposure reduction by providing continuous visibility of the attack surface, mapping how attackers can move through the environment, and validating security controls through adversary simulation. In doing so, you will help the organization identify, prioritise, and reduce exploitable security risk in a way that is threat-informed, measurable, and directly tied to business impact.

To be successful in this role, you should have experience with:

• Attack surface discovery and asset attribution
  Ability to continuously identify internet-facing assets, shadow IT, domains, subdomains, certificates, cloud services, APIs, SaaS exposures, third-party-hosted assets, and assets with unclear ownership
• Risk-based exposure prioritisation
  Ability to prioritise the most material exposures by combining exploitability, business criticality, asset ownership, threat intelligence, vulnerability data, and likelihood of attack
• Threat-informed attack surface analysis
  Ability to enrich attack surface findings with attacker techniques, active exploitation trends, KEV data, offensive security teams findings, and sector-specific threat intelligence

Highly valued skills for this role include:

• Hands-on experience with EASM/ASM platforms
  Experience using tools such as external attack surface management, CAASM, vulnerability management, cloud posture, and exposure management platforms
• Cloud, identity, SaaS, CI/CD and API exposure knowledge
  Understanding of common attack surface risks across AWS, Azure, GCP, Entra , Active Directory, Kubernetes, APIs, internet gateways, and exposed management interfaces
• Understanding of Breach and Attack Simulation techniques
  Ability to use BAS outputs to validate whether identified exposures are exploitable, test control effectiveness, simulate attacker behaviours, and support evidence-based prioritisation

You may be assessed on the critical skills required for success in this role, including risk and controls, change and transformation, business acumen, strategic thinking, digital and technology, and job-specific technical skills.
