Senior Penetration Tester

Remote

£70000-£85000 + Bonus + Benefits

A leading enterprise organisation is seeking a Senior Information Security Tester / Senior Penetration Tester to join a growing cyber security function. This is a highly visible, hybrid role combining hands-on penetration testing with strategic input, stakeholder engagement, and mentoring responsibilities.

This position is ideal for a well-rounded security professional who can act as a “go-to” resource across the business. You will deliver a mix of web application and API penetration testing, security assessments, and advisory work - going beyond pure testing to help shape how security engagements are approached, scoped, and executed.

Key Responsibilities

• Perform web application, API, and infrastructure penetration testing
• Lead and contribute to end-to-end security assessments, from scoping through to reporting and remediation advice
• Act as a subject matter expert, providing guidance to internal teams on testing strategies and best practice
• Support and mentor junior team members, raising overall security capability
• Contribute to secure design and vulnerability management discussions across the business
• Engage with stakeholders to clearly communicate risks and remediation actions

What We’re Looking For

• Strong experience in web application and API penetration testing (core focus)
• Broad technical capability across multiple domains – a true “jack of all trades” with deep specialism
• Experience delivering practical security guidance, not just identifying vulnerabilities
• Understanding of penetration test scoping and methodology design
• Exposure to malware development and advanced testing techniques
• Knowledge of PCI-DSS and regulated environments
• Relevant industry certifications (e.g. OSCP, CREST, GIAC or similar) preferred
• Strong communication skills, with the ability to influence both technical and non-technical stakeholders

Why Apply?

• Opportunity to operate as a trusted security advisor, not just a tester
• Hybrid role balancing hands-on technical work with strategic influence
• Access to complex, large-scale environments and varied testing challenges
• Collaborative culture with a strong focus on learning, mentoring, and continuous improvement

This is an excellent opportunity for a senior tester looking to step into a broader, more consultative role while still remaining technically hands-on.
