The Role

We’re looking for a Senior Penetration Tester to join our growing security team, delivering high‑quality testing across web applications, networks, cloud environments, and APIs for a diverse range of clients.

This is a hands‑on role where you’ll help organisations identify and remediate real‑world security risks. You’ll also have the opportunity to contribute to improving our tooling, methodologies, and knowledge sharing within the team.

If you’re passionate about offensive security and enjoy practical, problem‑solving‑led work in a collaborative environment, we’d love to hear from you.

What You’ll Be Doing

Deliver penetration testing engagements across:
- Web applications
- Network and infrastructure
- Cloud environments
- APIs and supporting services
Identify vulnerabilities, validate exploitability, and clearly articulate risk.
Produce concise, actionable reports suitable for both technical and non‑technical stakeholders.
Support clients with vulnerability remediation and technical explanations.
Contribute to the evolution of testing methodologies and internal tooling.
Collaborate closely with other testers and support the development of junior team members.

Essential Skills & Experience

2+ years’ experience in a hands‑on penetration testing role.
Strong experience with web application and network/infrastructure testing.
Solid understanding of common vulnerability classes (e.g. OWASP Top 10).
Good working knowledge of Linux, Windows, and Active Directory environments.
Experience testing or reviewing cloud environments (AWS, Azure, GCP).
Proficiency with common tooling such as:
- Burp Suite
- Nmap
- Nessus (or equivalent)
- Kali Linux
Scripting experience in Python, Bash, or similar, for automation or custom tooling.
Ability to clearly communicate technical findings and risk.

Nice to Have

Relevant security certifications (e.g. OSCP, OSWE, CRTO, Cyber Scheme incl. CSTM or CSTL).
UK Security Clearance
Experience with capture‑the‑flag platforms, labs, or challenge‑based learning.
Mobile application testing experience.
Prior consultancy or client‑facing experience.
