Interested in getting away from the grind of endless similar penetration tests? Keen to stretch yourself into a more managerial role over time, building up a capability around you?

We are working with a leading security services provider who are in the process of standing up their Offensive Security capability. The work will be focused on providing services such as Web App testing, Infrastructure testing and Code Review services to clients whilst also looking at how to develop that side of the company further.

•Customer engagement, through the scoping process, tool selection and overall delivery

•Run and take ownership of services such as Vulnerability Assessments, Code Review and Penetration Testing

•Engage in a cross departmental way in order to spot and develop opportunities for unique services and products.

•Experience delivering either Application or Infrastructure penetration tests to a high standard

•Working with customers in order to scope numerous services, from penetration testing to phishing

•Ideally you will have experience working on Code Reviews, in order to highlight vulnerabilities

•High level stakeholder communication skills, from technical individuals through to non-technical stakeholders

•Some experience delivering training or mentoring would be advantageous

•Industry certifications would be a plus, such as CRT, CSTM, CCT App or Inf or Offensive Security certifications

This role gives someone tired of the same old testing jobs the chance to build a function around them over time, which could be career defining.
