The Role
Lead security engineering across enterprise networks, devices, cloud systems, identity, and access environments. Design reusable security architectures, automated governance controls, authentication and authorization models, privileged access controls, secrets management, and policy-as-code. Diagnose and remediate security weaknesses, lead threat modeling, implement scalable controls for human and non-human identities including AI agents, and advise technology teams on complex security architecture decisions.
Summary Generated by Built In
Technology is at the heart of everything we do at CFC. We’re looking for a Lead Security Engineer to shape and deliver security across our networks, devices, identity and access environment.
This is a senior individual-contributor role for an engineer who combines strong technical judgement with sustained, hands-on delivery. You’ll solve complex, cross-functional security challenges, turning requirements and identified risks into practical, effective controls.
You’ll design how people, devices, services and non-human identities securely access our systems and data. Working across our technology teams, you’ll create reusable security architectures, implement and automate controls, diagnose weaknesses and ensure that security remains effective as our technology environment evolves.
At CFC, people are trusted to take ownership, challenge how things are done and deliver meaningful change. You’ll have the opportunity to influence security architecture across the business while working in an open, supportive and low-ego environment where ideas are welcomed
About the role
- Design, implement and operate highly automated security governance and controls across network, device, identity and access systems.
- Architect reusable security services for enterprise systems, integrating governance, protection, detection, response and recovery capabilities.
- Design and implement access controls for human and non-human identities, including service and agentic AI identities.
- Strengthen authentication, authorisation, secrets management, audit and privilege segmentation across systems and services.
- Implement scalable access-control models and access policy-as-code, enabling teams to provision access consistently and securely.
- Embed security governance and controls into code, cloud and AI architectures, including network segmentation and identity controls.
- Diagnose and remediate identity, infrastructure and access-control weaknesses, identifying root causes and implementing controls that prevent recurrence.
- Lead cross-functional security design and threat-modelling activities, translating risks into layered and prioritised engineering improvements.
- Automate security policies and guardrails across workflows and endpoints, including the appropriate use of AI augmentation.
- Act as a technical authority for network, device and identity security, advising technology teams on complex architecture and access-control decisions.
About you
We’re looking for an experienced security engineer who combines principal-level judgement with a practical, hands-on approach. You’ll bring:
- Deep experience designing and engineering security across enterprise networks, devices, identity and access.
- A strong understanding of network segmentation, identity controls and security architecture across cloud systems.
- Hands-on experience implementing identity and access management and privileged-access controls across enterprise identity platforms.
- Strong knowledge of authentication, authorisation, secrets management, audit, least privilege and privilege segmentation.
- Experience designing access for human and non-human identities, including addressing excessive permissions, exposed secrets and access-governance weaknesses.
- Experience implementing role-based or attribute-based access control, automated policy enforcement or access policy-as-code at scale.
- The ability to create effective security architectures and navigate trade-offs between security, accessibility, decentralisation and performance.
- The ability to automate controls through code, policy and workflow automation.
- Strong technical judgement, with the ability to influence cross-functional technology teams through clear and credible architectural reasoning.
You’ll enjoy taking ownership of complex problems, challenging established approaches and working collaboratively to make security effective by default. This is an opportunity to make a visible impact in a business that gives people the trust and responsibility to shape what comes next.
