The Role:

This is a hands-on contract for an engineer who can turn security requirements into practical platform capabilities that development teams will actually use.

You will work across cloud infrastructure, identity and application environments, improving how access, credentials and workload trust are managed. The emphasis is on building and automating, not producing policy documents or operating as a review-only security function.

What You Will Be Doing:

• Build reusable security components and controls through infrastructure as code.
• Automate identity, credential and workload-authentication processes.
• Develop integrations and internal tooling that remove repetitive operational work.
• Improve security patterns across cloud infrastructure, applications and delivery pipelines.
• Diagnose production issues that cut across platforms, services and security controls.
• Work with engineering teams to make secure approaches straightforward to adopt.
• Take ownership of the reliability and operational quality of what you deliver.

What You Bring:

• Strong engineering judgement across security, platform, infrastructure or identity domains.
• Practical experience automating cloud or production environments.
• Good working knowledge of infrastructure as code and modern delivery pipelines.
• Scripting or software engineering capability using Python, Go, Bash or a comparable language.
• Familiarity with container platforms, cloud services and secrets-management tooling.
• An understanding of authentication and authorisation concepts such as OIDC, JWT and workload identity.
• A pragmatic approach that balances security, usability and delivery speed.
• The ability to investigate root causes rather than repeatedly treating symptoms.
• Strong backround in financial servcies companies
