Enabling Enfuce to innovate at pace while maintaining a robust security posture.

What you'll be doing:

• Act as a Senior Application Security specialist within the Information Security team. You will contribute directly to Enfuce’s technology risk management and security assurance capabilities in a regulated financial services environment.

• Embedded secure software development lifecycle (SSDLC) practices across engineering teams and ensuring security is considered from early design through to build, deployment and ongoing operation.

• Work closely with the Platform and Engineering teams to assess and influence the security of cloud-native, API-driven applications with a strong focus on AWS based environments.

• Integrate and continuously improve automated application security testing within CI/CD pipelines, including SAST, DAST and software composition analysis (SCA). Ensuring that the tools provide meaningful and actionable results.

• Facilitate and lead threat modelling exercises and security design reviews for new and existing services. You will identify risks early and supporting teams with proportionate and pragmatic mitigations.
