Job in a nutshell
As our UK&I Pentesting Operations Lead, you will be responsible for the operational leadership, governance and continuous improvement of our penetration testing services across the United Kingdom and Ireland.
You will oversee the end-to-end lifecycle of penetration testing engagements delivered through a combination of internal teams and trusted specialist partners, ensuring that engagements are effectively scoped, scheduled, delivered, quality assured and commercially managed.
