Job Specifications

We are seeking a Senior DevSecOps Engineer to support a greenfield mobile and web application build in a regulated environment. This role focuses on security governance, architecture guidance and assurance across Azure, AWS, Kubernetes and SaaS platforms.
You will define security standards, guide engineering teams on best practice, and ensure solutions meet Cyber Essentials Plus, ISO 27001 and Zero Trust requirements. This is not a BAU ops role-you'll act as the bridge between engineering and governance to ensure secure delivery from day one.
What You'll Be Doing
Define and maintain multi-cloud security standards and reference blueprints
(Azure Policy/Initiatives, AWS Control Tower, SCPs)
Own security architecture patterns and contribute to HLDs, LLDs, threat models and risk assessments
Set assurance and evidence requirements for internal teams and third-party suppliers
Establish policy-as-code standards, including exception handling and risk ownership
Define identity and access controls
(Entra ID Conditional Access, MFA, PIM, AWS IAM federation)
Govern SaaS security onboarding (SSO, OAuth, DLP, vendor assessments)
Ensure solutions align with regulatory and audit requirements
Educate and influence teams through clear guidance, reviews and security clinics
What We're Looking For
Essential
Strong DevSecOps/Cloud Security experience across Azure and AWS
Background in regulated environments (ISO 27001, similar frameworks)
Solid understanding of IaaS, PaaS and SaaS security risks
Experience working on greenfield web and mobile application builds
Excellent communication skills and ability to influence engineering teams
Desirable
Security or cloud certifications (AZ-500, SC-100, SC-200, AZ-700, AWS Security Specialty, CISSP)
Experience with architecture governance or blueprint catalogues
Working knowledge of Kubernetes/container security (AKS/EKS)
Technology Exposure
Hands-on involvement may be required for validation and assurance:
Azure: Policy, Defender for Cloud, Entra ID, PIM
AWS: Control Tower, SCPs, Security Hub, GuardDuty, IAM
Security & Monitoring: Microsoft Sentinel (KQL), Defender XDR
Governance: Blueprint repositories, risk registers, ITSM/CAB
If this sounds of interest please send your cv for review.
