⏳ Initial 3 months (rolling contract) - OUTSIDE IR35

Start ASAP

You'll be joining as a Senior, hands-on Cloud & Information Security Engineer for an urgent contract engagement to take ownership of cloud security and technical information security in a regulated environment.

This is a delivery-first role, not advisory. You’ll be responsible for designing, implementing and operating secure cloud infrastructure and security controls that will stand up to audit and regulatory scrutiny, with clear handover at the end of the engagement.

What you’ll deliver:

Ownership of day-to-day technical information security controls
Secure cloud infrastructure design and build (AWS preferred) using security-by-design
IAM enforcement (least privilege, MFA, segregation of duties)
Centralised security logging, monitoring, alerting and vulnerability management
Infrastructure-as-Code, configuration management and automation
Secure networking, encryption, backup and resilience
Technical leadership of pen testing, vulnerability scans and remediation
Support CI/CD pipelines and secure change management
Produce clear technical documentation and audit-ready evidence
Act as technical lead during security incidents

What we’re looking for:

5–8+ years hands-on cloud engineering & information security experience
Strong AWS or Azure experience (one primary cloud, end-to-end ownership)
Deep IAM, networking and cloud security implementation experience
Infrastructure-as-Code and automation mindset
Practical application of ISO 27001 / NIST
Experience operating in regulated or audit-driven environments
Comfortable working independently and delivering at pace
Security or cloud certifications are beneficial, but not essential

This role will suit someone who has owned security controls hands-on, not just advised on them
