Job Description:

ReRoot Cyber is seeking highly skilled and forward-thinking penetration testers to join one of the UK’s most respected testing teams for their Scotland division.

This is an independent, privately owned testing consultancy led by industry-recognised names who are hackers at heart.

This team is led by an active penetration tester who understands the niggles of day penetration testing operations. As a result, engagements are centred around making your day-to-day responsibilities as easy as possible, with a pure focus on value added testing.

They have no problem with 2+1’s and pub sec engagements… but that’s not where they phish.

Most of your time will be spent on advanced testing and large-scale engagements that give you the opportunity to collaborate with wider technologists. (engineers, developers and blue teamers)

If you thrive on bringing ideas to life, creating bespoke tools and adding true value to your clients, then this is the penetration testing team for you.

This is a home based position with very very very limited travel & public sector work.

Full right to work in the UK is required

Ideally you will:

• Hold active CHECK Team Member Status
• Have experience with creating bespoke tools & scripts
• Possess strong Infrastructure/Networking Knowledge
• Have a desire to continually learn about the security of new technologies
• Hold a genuine enthusiasm for solving problems & thinking outside the box

Despite being a CHECK penetration testing provider, the business is increasingly focused on commercial engagements in areas we know are proving popular amongst testers. (Cloud, OT, Red & Purple Teaming)

If you want to work on technically challenging engagements for a team that has a board approved ‘hacker first’ mandate for their team, do get in touch to learn more.

Apply now or get in touch on 02079478806 to learn more.
