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
- 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? xwzovoh
- 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
- Technical & team interview (with the cyber team)
- Face‑to‑face interview with senior stakeholders
- HR final stage
