• Perform threat modelling and gap analysis, identifying vulnerabilities and systemic risks impacting source code, artifacts, and workloads.

Engineering Platform Security Enablement

• Establish standardised secure architecture and engineering patterns for build systems, CI/CD pipelines, runtime environments, and developer tooling.
• Define and enforce platform security baselines using policy-as-code and automated controls.
• Partner with platform owners to remediate critical gaps and implement scalable solutions for artifact integrity, access control, and configuration security.
• Integrate vulnerability management, SBOM, provenance, and code-signing practices within engineering workflows.

Roadmap Development & Execution

• Prioritise identified gaps based on business risk, regulatory impact, and operational criticality.
• Collaborate with platform owners and engineering leads to build actionable security roadmaps, balancing quick wins with long-term strategic improvements.
• Partner with engineering teams to design, develop, and embed security patterns and best practices into engineering platforms.

Stakeholder Engagement & Governance

• Serve as a trusted advisor to platform owners, senior technology stakeholders, and Cybersecurity leadership, translating technical risks into business impact.
• Represent the function in key governance forums, providing updates on maturity progress, roadmap delivery, and risk posture.
• Influence and align stakeholders across federated engineering teams to ensure consistent adoption of cybersecurity best practices.

Continuous Improvement

• Track and report maturity scores, ensuring measurable improvement across platforms.
• Continuously evolve the maturity framework in response to emerging threats, technology evolution, and regulatory expectations.
• Drive a culture of secure-by-design engineering through engagement, advocacy, and knowledge sharing.

The ideal candidate will have the following:

• Proven expertise in Cybersecurity within large-scale, regulated financial institutions or similarly complex environments.
• Deep technical knowledge of engineering platforms, including CI/CD systems, build tools, artifact repositories, runtime environments, and developer tooling.
• Strong experience with DevSecOps practices, including secure pipeline design, integration of security scanning tools, and automation of security controls.
• Strong knowledge and understanding of service mesh, cryptography, network security, application security, vulnerability management, and risk management.
• Demonstrable ability to conduct threat modelling, platform security assessments, and gap analysis.
• Experience building and implementing maturity models, frameworks, or roadmaps in complex enterprise environments.
• Strong stakeholder management skills, with the ability to influence senior leadership and drive change across federated technology teams.
• Excellent communication skills, with the ability to translate technical risk into business impact.

Desirable Skills/Experience Although not essential, the following skills are desired by the client:

• Professional certifications such as CISSP, CISM, CCSK, CCSP, or equivalent.
• Hands-on knowledge of cloud security (AWS, Azure, GCP) and container orchestration platforms (e.g., Kubernetes).
• Experience in international and diverse environments, with exposure to regulatory engagement.
• Familiarity with engineering excellence practices such as SLSA, supply chain security, SBOM, or secure developer tooling initiatives.
