Job Specifications

Senior Security Architect (Azure / Cloud Security)

Salary: Up to £75,000 base (DOE) + Up to 10% bonus

Location: Remote / Home-based with occasional client travel

We’re supporting a cybersecurity consultancy that is growing its security architecture practice, and they’re looking for a Senior Security Architect with strong Azure and Microsoft security experience.

This role sits at the intersection of cloud security architecture, consulting, and enterprise transformation. You’ll be working with organisations that are modernising their platforms across Azure, Microsoft 365, hybrid cloud and on-prem environments, helping them embed security into architecture from the outset.

This isn’t a governance-only role, they’re looking for someone comfortable translating security principles into real technical architecture.

As a Senior Security Architect, you’ll work directly with clients to design and deliver security architecture across complex environments.

Typical responsibilities include:

Designing secure Azure and Microsoft cloud architectures, including identity, network, and platform security
Leading security architecture engagements across cloud and hybrid environments
Producing technical deliverables such as threat models, risk assessments, security design documentation and architecture blueprints
Aligning architecture with recognised frameworks such as NIST, CIS, ISO 27001, NCSC CAF and Cyber Essentials
Acting as a technical advisor to client engineering and leadership teams
Supporting cloud transformation programmes where security needs to be embedded from design through to implementation

You’ll be working with organisations across multiple sectors, so the work is varied and often complex.

They’re looking for someone who can combine technical depth with strong architecture thinking.

Key experience includes:

Designing security architecture across Azure and Microsoft cloud environments
Strong understanding of identity, access control, network security, logging/monitoring and platform security in Azure
Experience producing architecture artefacts (threat modelling, design documents, security blueprints)
Familiarity with enterprise security frameworks and control frameworks
Experience working in consulting, advisory, or client-facing environments

Experience across Microsoft security tooling (Defender, Sentinel, Entra ID, Microsoft 365 security stack) would be highly beneficial.

Certifications (desirable)

Microsoft security certifications are particularly valued, including:

SC-100 – Microsoft Cybersecurity Architect
SC-900 – Microsoft Security Fundamentals
AZ-900 – Azure Fundamentals
AZ-104 – Azure Administrator
AZ-305 – Azure Solutions Architect

Additional certifications such as CISSP, CISM, CISA, SABSA, TOGAF or ISO 27001 Lead Auditor/Implementer are also beneficial.

Why this role

This consultancy has built a reputation for delivering high-quality security architecture rather than checkbox compliance work.

You’ll have the opportunity to:

Work on complex cloud security and transformation projects
Influence how organisations design security into Azure and Microsoft environments
Help shape the growth of the consultancy’s architecture capability
Join a collaborative, technically strong team
