Role Overview :

We are looking for a hands-on Cloud Security Engineer to join our growing cybersecurity practice. This is an engineering-first role so we are looking for someone who builds, configures, and secures cloud infrastructure day-to-day, not just someone who writes policies and presents to stakeholders.

You will be embedded within financial services and public sector client engagements, working directly alongside engineering and platform teams to design and implement secure cloud architectures, integrate security into delivery pipelines, and improve cloud security posture across primarily AWS-based environments. You will bring a strong cloud engineering background with a solid, practical understanding of security and a genuine desire to shift security left across the full delivery lifecycle.

Conduct threat modelling exercises, cloud security posture reviews, and risk assessments for cloud platforms and workloads

Work within scaled agile delivery teams, contributing security requirements and controls to sprint cycles and platform roadmaps

Provide technical security assurance for application deployments, third-party integrations, and SaaS product onboarding

Support incident response planning and contribute to cloud resilience and recovery design for client-hosted services

Communicate security risks and remediation priorities clearly to technical peers and, where needed, to technical leads and delivery managers

About the candidate:

A minimum Bachelor's degree (2.1 or above) in Cyber Security, Computer Science, Software Engineering, or a related technical discipline

Background in Dev Sec Ops , secure software engineering, or application security, with direct experience integrating security into CI/CD pipelines

Exposure to cloud security posture management, workload protection, or equivalent cloud-native security tooling

Familiarity operating within agile delivery frameworks (Scrum, SAFe, or equivalent)
