Cloud Security Engineer; Automation & Tooling - Engine Starling

As a Cloud Security Engineer at Engine, you will be a hands‑on builder, responsible for engineering and automating the security of our core platform. Your primary mission is to treat security as an engineering discipline, creating robust, scalable, and automated solutions to protect our cloud infrastructure and development lifecycle. You will spend your time writing code (Go, Python), defining secure infrastructure‑as‑code (Terraform), and building the tooling that ensures our platform is secure by design and compliant by default.

This is a role for an engineer who loves to build, automate, and solve complex security problems through code. You'll be working on projects covering identity and access management, cloud and network security, vulnerability management, security monitoring, security hardening, compliance reviews, and more.
It’s a very varied role with lots of close interaction with the infrastructure, security engineering, cross‑cutting and compliance teams.

At Engine by Starling, we are on a mission to find and work with leading banks around the world who have the ambition to build rapid growth businesses on our technology. Our purpose is underpinned by five values:
Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working:
We have a hybrid approach to working here at Engine – our preference is that you’re located within a commutable distance of our offices so that we can interact and collaborate in person.

• Design, build, and maintain security automation and tooling to enforce security controls and simplify compliance (e.g., automating evidence collection for frameworks like SOC 2, ISO 27001, or PCI DSS)
• Build, manage, and automate identity and access management controls to ensure secure access to our cloud platforms and applications
• Write and review Infrastructure‑as‑Code (Terraform) to securely configure our AWS and GCP environments
• Secure our CI/CD pipelines by implementing and interpreting results from SAST/DAST/SCA tools and ensuring the integrity of our software supply chain
• Develop and maintain preventative and detective security controls within our cloud environments, responding to and automating the remediation of security alerts
• Implement and automate technical controls based on the findings from security assessments, audits, and architecture reviews
• Engineer solutions to secure our Kubernetes environments, focusing on RBAC, network policies, and runtime security
• Collaborate with engineering teams to implement security best practices and provide hands‑on support for remediation efforts
• Contribute to incident response efforts, including the investigation, remediation, and post‑mortem analysis of security breaches
