Security Architect

Security Architect – UK Remote

Salary: £90k basic plus excellent benefits package!

A rare opportunity to define security from the ground up

This is a unique opportunity to step into the first-ever Security Architect role , with full ownership to shape how security is designed, embedded, and scaled across a modern cloud-native platform.

From day one, you will set the direction. You won’t be inheriting legacy structures or rigid frameworks — you will be creating the security architecture, principles, and standards that everything else is built on .

This is a high-impact role where security is elevated to a core engineering capability, deeply embedded into the platform’s design rather than applied after the fact.

What you’ll be doing

You will act as the lead authority for security architecture , defining how security operates across identity, application, data, network, and cloud layers.

Your responsibilities will include:

• Defining and owning the end-to-end security architecture strategy
• Establishing a Zero Trust, identity-first security model across a cloud-native SaaS platform
• Embedding security-by-design principles into engineering and platform development
• Leading structured threat modelling across systems, services, and integrations
• Translating security risks into clear architectural controls and practical remediation approaches
• Defining security patterns and reference architectures for engineering teams to reuse
• Ensuring secure scaling across multi-tenant SaaS environments
• Shaping security telemetry, detection, and response design aligned with operational readiness
• Aligning architecture with industry standards such as ISO 27001, NIST, and Zero Trust frameworks
• Supporting incident response design and continuous security improvement

Why this role is different

This is not a maintenance or compliance-focused security role.

You will:

• Be the first dedicated Security Architect in the organisation
• Own the security vision and architectural direction from day one
• Influence how engineering teams design and deliver software securely
• Establish the guardrails, standards, and patterns that define the platform’s future
• Operate as a design authority, not a gatekeeper
• Work at the intersection of architecture, engineering, and security leadership

What we’re looking for

You’ll likely bring experience such as:

• Proven background as a Security Architect or senior security specialist
• Strong expertise in cloud-native SaaS environments
• Deep understanding of Zero Trust architecture and identity-centric security models
• Hands-on experience with Microsoft Azure security stack (Entra ID, Defender, Sentinel, networking/security controls)
• Strong experience in threat modelling and risk-based security design
• Knowledge of multi-tenant SaaS security challenges , including data protection and resilience
• Familiarity with ISO 27001 or similar security frameworks
• Ability to influence senior stakeholders and engineering teams in a pragmatic, delivery-focused way

Nice to have

• Experience building or securing enterprise SaaS or PaaS platforms at scale
• Exposure to financial systems or ERP-style platforms
• Experience working with external auditors or security assessors
• Background in highly regulated or compliance-driven environments
