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
