Senior Security Architect

Company: Anson McCade
Apply for the Senior Security Architect
Location: London
Job Description:

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.
