Senior Security Architect

About the Role

Methods is looking for a Senior Security Architect to help clients deliver secure, resilient and modern technology solutions across complex digital transformation programmes.

As a trusted security advisor, you will work directly with client stakeholders, architects, engineers and delivery teams to shape secure solutions, navigate technical challenges and provide pragmatic security guidance that supports successful delivery. You'll combine strong technical expertise with consultancy skills, helping clients balance security, risk, cost and operational requirements across cloud, hybrid and enterprise environments.

This is a hands-on consulting role for someone who enjoys engaging with customers, solving complex problems and influencing outcomes across both technical and business audiences.

• Advising on secure architectures across Azure, AWS, SaaS, enterprise applications and hybrid infrastructure.
• Supporting clients in embedding security-by-design principles into new and existing services.
• Translating complex security requirements into practical and achievable technical solutions.
• Producing clear, risk-based security recommendations and presenting findings to both technical and non-technical audiences.
• Supporting design authorities, architecture forums and technical decision-making processes.
• Working collaboratively across multidisciplinary teams to ensure security enables delivery rather than becoming a barrier to it.
• Contributing to Methods' security capability, including best practices, reusable patterns, mentoring and thought leadership.

Desirable Experience

• Experience delivering security architecture within government, healthcare, critical national infrastructure or other regulated sectors.
• Cloud migration, platform modernisation or digital transformation experience.
