Cyber Security Consultant (Penetration Tester)

Moore Kingston Smith is seeking an experienced Cyber Security Consultant specialising in penetration testing to join our client-facing advisory team. You will join an NCSC-recognised cyber security team within our Risk Advisory practice, supporting a diverse portfolio of clients across multiple sectors.

This is a hands-on role focused on delivering penetration tests across web applications, APIs, and internal and external network infrastructure. You will also support Cyber Essentials Plus assessments and wider technical security reviews, including vulnerability assessments, configuration reviews against recognised benchmarks, and cloud security reviews. You will identify and safely validate security weaknesses, explain the associated business risks clearly, and provide practical remediation advice tailored to each client.

Technical delivery will account for at least 70% of the role and will remain the core focus. Depending on your experience, interests and business requirements, there may also be opportunities to contribute to broader cyber security engagements, including cyber maturity assessments, security control reviews, audit readiness activities and security design advisory work. Typically, this would represent up to 30% of your time and provides an opportunity to broaden your consulting expertise while supporting clients across a wider range of security challenges.

We are looking for a proactive consultant with strong technical fundamentals, sound professional judgement and a genuine interest in helping clients improve their security posture. This role offers the opportunity to deepen your offensive security expertise while contributing to the continued growth of a collaborative and commercially focused cyber security practice.
