Principal Security Consultant (Offensive Services)

Job Description: Principal Security Consultant (Offensive Services)

Why Join Secure Impact?

Secure Impact is entering a pivotal and exciting stage of growth. Founded by renowned cybersecurity expert James Lyne and affiliated with the SANS Institute, we are a company that has achieved exceptional feats in just four years. As a purpose-driven team, we focus on high-quality, meaningful offensive security services rather than commoditised penetration testing.

Our team is already highly capable, working on complex penetration testing engagements and now wants to continue to push the boundaries of advanced offensive security. This role is about building on that excellence. We are developing further capabilities for red team assessments and more advanced offensive services that empower organisations to strengthen themselves against attackers in meaningful ways.

This is a rare opportunity to join a team that prides itself on delivering bespoke, manual and creative offensive security services that are purpose driven. At Secure Impact, culture and values are at the core of everything we do. We’re highly collaborative, technically curious, and driven to make a real difference for the organisations we work with.

We are looking for a Principal Security Consultant who shares our vision. You will work closely with and report into the General Manager, lead a talented team of penetration testers, and help shape Secure Impact’s offensive services into the next phase of their evolution. This includes hands-on technical/work delivering offensive services, while mentoring and supporting the upskilling of the team to offer further advanced services which our clients need.
