What You'll Do Red & Blue Team Leadership Lead, grow, and mentor both the Red Team (offensive) and Blue Team (defensive), fostering a culture of continuous adversarial thinking and security resilience.

Communicate and present the security strategy, architecture, andassuranceposture to customers, partners, regulators, and auditors. Support the onboarding of new banking partners by ensuring platform security and stability meet required standards. Organizational Impact Strengthen the visibility and authority of the security function within the broader organization. Introduce and champion digital security tooling to enhance detection, response, and overall security operations. Continuously raise the security bar across teams through training, awareness, and policy enforcement. Your profile What You Bring Several years of experience in product security or security engineering, ideally within regulated SaaS, fintech, or banking environments.
