How you will make a difference

Triodos Bank wants to preserve the trust of its customers as a custodian of their money and personal data. Realising and maintaining secure IT systems and working procedures are vital to achieve this goal.

You are a trusted advisor on security aspects to other ICT teams and projects. You will collaborate on the implementation of changes and improvements to our cyber defences. You will work closely together with the Security Operations Centre and assess the impact of alerts and incidents.

In this role, you will perform in-depth analysis in highly specialised areas of cyber security, working independently and proactively to identify risks and opportunities for improvement. You will coordinate security tests by external providers. Findings from these tests complemented with your findings will be translated into concrete remediations and enhancements, which you will discuss with internal stakeholders and implement together with IT teams and our external security provider. You will also provide expert advice on security-related projects and changes, substantiated by best practices or aligned with relevant guidelines, regulations, and internal policies.
