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 becreating 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
