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.
