VIQU are partnering with a leading financial services organisation to recruit a Senior Penetration Tester into their growing Cyber Defence function. This is a senior-level offensive security role sitting within a collaborative team spanning Offensive Security, SOC, Threat Intelligence and Vulnerability Management. The successful candidate will lead complex penetration testing engagements across web applications, cloud platforms, and critical business systems, whilst also contributing to Red Team exercises, Purple Team activities, attack simulations, and wider cyber defence initiatives. This role would suit an experienced penetration tester or offensive security professional who is comfortable operating independently, engaging with stakeholders, mentoring others, and taking ownership of security testing engagements from initial scoping through to delivery and remediation.
