Senior Cybersecurity Architect

We’re looking for an experienced Security Architect to lead the design and delivery of secure, resilient technology across platforms, applications and cloud services.

This is a hands‑on leadership role where you’ll work closely with Agile engineering and delivery teams to embed security throughout the software development lifecycle — from initial architecture and design through to implementation and ongoing operation.

You’ll bring a pragmatic approach to security, balancing risk, cost, usability and business requirements, while helping teams adopt modern security practices and technologies.

What you’ll be doing

• Lead the security architecture and secure design of cloud services, platforms and applications.
• Identify vulnerabilities and security risks within system designs and recommend pragmatic, proportionate mitigations.
• Embed DevSecOps, Continuous Security, CI/CD and secure software development practices across delivery teams.
• Work across areas including Cloud Security, AI/ML, Data, M365 and Security Architecture.
• Apply recognised security frameworks, standards and regulations including NCSC, NIST, ISO 27001, PCI DSS and GDPR.
• Assess application, infrastructure and platform architectures to identify security weaknesses and opportunities for improvement.
• Perform and support security testing across software, infrastructure and cloud environments.
• Apply strong knowledge of network security, TCP/IP, OSI, OWASP, PKI, TLS and cryptographic controls.
• Work closely with engineers, architects, product teams and senior stakeholders to build security into delivery from the outset.
• Lead, coach and mentor security engineers and junior team members, supporting their technical and professional development.
• Share security knowledge and best practice with both technical teams and clients.
• Help drive innovation by evaluating and applying new security technologies, methodologies and approaches.

What we’re looking for

You’ll have a strong background in Security Architecture, Cloud Security or secure technology delivery, with experience designing and implementing security across modern technology environments.

You’ll ideally bring:

• Proven experience delivering secure cloud services and solutions.
• Strong understanding of security architecture, threat identification and risk mitigation.
• Experience across at least one of AI/ML, Cloud, Security Architecture, M365 or Data.
• Strong knowledge of NCSC, NIST, ISO, PCI DSS and GDPR.
• Background in application architecture, software development and/or infrastructure architecture.
• Hands‑on experience with security testing and vulnerability assessment.
• Practical understanding of DevSecOps, CI/CD and Continuous Security.
• Strong knowledge of network security, OWASP, PKI, TLS and cryptographic controls.
• Experience managing, coaching or mentoring technical professionals.
• Excellent communication skills, with the ability to translate complex security concepts for both technical and non-technical audiences.
• A pragmatic mindset and the ability to balance security, usability, cost and business risk.
• Identity and Access Management (IAM), authentication and authorisation.
• Governance, Risk and Compliance (GRC).
• Operational security and security operations.
• Supply chain security and third‑party risk.
• Penetration testing qualifications such as OSCP, CREST, TIGER or equivalent.
• Experience leading Security Engineers, Architects or junior security professionals.
