Penetration Tester, Closed Door Security
Location: Remote (UK only)
Salary: £30,000 to £50,000 depending on experience
About Us
Closed Door Security is an award winning, CREST-accredited penetration testing company founded in Scotland, operating globally across the UK, UAE and USA. We work with household names across financial services, critical national infrastructure, maritime, education and the public sector. We are not a generalist IT consultancy. Penetration testing is all we do, and we do it properly.
The Role
We are looking for a mid-level penetration tester to join a highly capable team. You will be delivering real engagements from day one across web applications, external and internal infrastructure following a Threat-Led testing methodology. We do not micromanage. You will be expected to manage your own time, write clear reports, and communicate professionally with clients.
What We Need From You
You will have at least one year of hands-on penetration testing experience and a solid understanding of networking fundamentals and web application security. CHECK Team Member status or equivalent is preferred, and you must be eligible for UK security clearance. Certifications such as OSCP, CREST CRT, CSTM or CSTL are a strong indicator you are the right fit.
You should be comfortable with tools like Burp Suite and Nessus, familiar with OWASP and MITRE ATT&CK, and capable of writing reports that a board member and a sysadmin can both read and act on. Willingness to travel occasionally for on-site work is required. Thinking outside the box is a must.
What You Get
Salary is £30,000 to £50,000 based on ability and certifications, with a bonus scheme on top. You will get a structured development plan, support toward further certifications, monthly private therapist sessions, remote working, company pension, sick pay, a cycle to work scheme, and an employee referral programme. We also run company trips for the team, attendance optional.
Background checks are a condition of employment. UK applicants only. We are unable to sponsor any visas.
