Senior Cyber Security Architect (Permanent)

London (Hybrid)

We're looking for a Senior Cyber Security Architect to join a growing organisation at a pivotal point in its cloud security journey.

Following recent changes, this role is about bringing senior technical leadership, stability, and direction into the cyber team - someone who can define what good looks like, mentor junior specialists, and shape cloud security in a pragmatic, real-world way.

This is an AWS-focused role, with significant influence over how cloud security is designed, implemented, and matured across the organisation.

What you'll be doing

• Acting as the senior security authority for cloud architecture and engineering, with a strong focus on AWS
• Leading secure cloud onboarding and greenfield build activity, defining standards, patterns, and guardrails
• Influencing architectural decisions and representing cyber security in design and review forums
• Mentoring and guiding junior team members across SOC analysis and vulnerability management
• Providing expert oversight of cyber risk, vulnerability (including vulnerabilities in code), and security analytics
• Supporting incident response, including zero-day scenarios, alerting, and SOC robustness
• Working closely with engineering and technology teams to embed secure-by-design practices
• Producing clear, meaningful security reporting and metrics for leadership

This role balances hands-on technical credibility with the ability to guide, influence, and enable - you won't be expected to do all the engineering yourself, but you'll know when and how to step in.

What we're looking for

Essential

• Strong, hands-on AWS cloud security experience (designing, building, and securing environments)
• Background in security architecture and security engineering
• Deep understanding of cyber risk, vulnerability management, and cloud security best practice
• Experience mentoring or supporting junior security professionals
• Pragmatic mindset - able to balance security, delivery, and business needs

Nice to have

• IAM experience (useful, but not essential)
• Experience in regulated or financial services environments
• Exposure to Azure (future consideration)
• Security certifications such as CISSP, CCSP, Security+, GCIH, etc.

Why this role?

• High-impact role shaping cloud security direction in a maturing environment
• Genuine autonomy and senior influence
• Opportunity to mentor and grow a developing cyber team
• Engineering-heavy cloud work during build phases, with less operational burden
• A role focused on doing security well, not just writing policy

Interview process

1. Technical & team interview (with the cyber team)
2. Face-to-face interview with senior stakeholders
3. HR final stage
