Senior Azure Platform Engineer — Security Focus

We’re hiring a Senior Azure Platform Engineer with a strong security focus to join a major UK enterprise organisation undergoing large-scale cloud transformation.

This is a hands-on senior individual contributor role within the Platform Engineering function, working at the intersection of platform, architecture, and cyber security to strengthen the organisation’s Azure security posture.

You’ll collaborate closely with Cyber Security (including SOC teams), Architecture, and Engineering to ensure the platform is secure by design and compliant by default.

This is an engineering-led role focused on hands-on implementation — not just governance or policy definition.

The Opportunity

You’ll take ownership of platform security posture — analysing risks, prioritising improvements, and driving adoption of secure standards across a complex Azure environment.

Working extensively with Azure Policy, Defender for Cloud, identity controls, networking, and Infrastructure-as-Code tooling, you’ll help establish secure platform foundations for multiple engineering teams.

Key responsibilities include:

• Establishing and enforcing Azure security baselines and policies
• Implementing and scaling policy-as-code and platform guardrails
• Reviewing technical designs and assessing security posture
• Working with SOC and cyber teams to identify and remediate platform risks
• Defining and implementing secure standards for infrastructure and services
• Supporting compliance across internal and customer-facing systems
• Partnering with architects and engineering teams to embed security into delivery

The role combines day-to-day platform ownership (BAU) with project-driven improvements as the platform continues to evolve.

What You’ll Bring

We’re looking for a hands-on senior engineer with strong technical depth and credibility:

• Strong experience with Microsoft Azure (particularly PaaS environments)
• Proven experience implementing Azure security controls hands-on (not just designing or advising)
• Strong experience implementing and enforcing Azure Policy at scale (policy-as-code, guardrails, compliance)
• Solid understanding of Azure networking and security controls (NSGs, ASGs, Private Endpoints, VNet design)
• Hands-on Infrastructure-as-Code mindset (Terraform, Bicep, ARM, etc.)
• Experience with tools such as Defender for Cloud, Key Vault, Sentinel
• Familiarity with CI/CD tooling (Azure DevOps, GitHub)
• Ability to assess risks and drive remediation through to completion
• Comfortable operating independently and owning outcomes
• Strong stakeholder engagement skills

You should be able to clearly articulate what you have personally built and implemented across Azure platform security.

Desirable certifications:

• AZ-500 Azure Security Engineer
• SC-100 Cybersecurity Architect
• AZ-305 Azure Solutions Architect
• CCSP

Why This Role Stands Out

• Senior individual contributor role with real influence
• Enterprise-scale Azure platform challenges
• Opportunity to shape security posture across a large estate
• Close collaboration with Cyber Security leadership
• Modern Azure-first environment
• Long-term transformation programme
• Platform standards impacting multiple engineering teams

Package

• Salary up to £80,000 per annum
• Performance-related bonus
• Strong pension contribution
• Private medical cover
• Generous annual leave + option to buy/sell days
• Life assurance
• Wellbeing support and employee benefits
