About the job you’re considering

Capgemini’s Global Cybersecurity Practice is home to over 4,000 professionals delivering secure, innovative solutions across IT and OT environments – from networks to cloud services and everything in between. Capgemini’s Technical Assurance Services (CTAS) team in the UK is a dynamic part of our Global Cybersecurity Practice. As a penetration tester in our CTAS team you’ll play a vital role in helping our clients detect, understand and manage their security risks. You’ll be responsible for undertaking rigorous tests that identify vulnerabilities which are present in the IT infrastructure, applications and networks on which our client’s businesses rely. You’ll employ both manual and automated techniques to simulate real world attacks which help our clients assess their security posture against any potential threats to their business. You’ll also be expected to keep your knowledge of the ever‑evolving threat landscape up‑to‑date and adhere to ethical guidelines, especially when handling sensitive data. As well as having proven technical skills, you’ll also need to demonstrate the strong communication skills needed to describe complex findings to a range of different, often non‑technical, stakeholders.

Hybrid working

The places that you work from day to day will vary according to your role, your needs, and those of the business; it will be a blend of Company offices, client sites, and your home; noting that you will be unable to work at home 100% of the time.

Your role

  • Deliver high‑quality penetration testing and consultancy services as well as a full range of security assessments (including specialist areas and IT Health Checks) in line with Capgemini’s policies, core values, methodologies, and commercial expectations.
  • Produce accurate, concise documentation including technical reports, executive summaries, scopes, and proposals.
  • Engage a variety of different stakeholders, some technically minded and others not, to ensure they understand work you have delivered.
  • Ensure relevance, maintain confidentiality, align with the QA manual, meet client expectations, and uphold Capgemini’s own standards.
  • Maintain strong technical expertise and contribute to service development by staying up‑to‑date with emerging threats, technologies, vulnerabilities and methodologies.
  • Share knowledge across the team, participate in research and involve yourself in initiatives which enhance capability.

Your skills and experience

  • Proven experience working in a Penetration Testing role as a certified Check Team Member (CTM) is essential.
  • Strong knowledge of penetration testing tools including Burpsuite, Metasploit, Nmap, etc.
  • Good knowledge of multiple Operating Systems (OS) including Windows & *NIX.
  • Ability to configure network devices, firewalls, IDS/IPS devices and wireless technologies.
  • Good understanding of common security standards and regulatory compliance such as GDPR, ISO27001 and PCI DSS.
  • Experience of testing AI / LLMs is desirable but not essential.
  • Excellent written and verbal communication skills (including writing detailed reports and providing clear recommendations for remediation).
  • Proven organisational skills which include working under pressure and dealing with ambiguity to meet deadlines.
  • Ability and willingness to work effectively and positively within a team e.g. collaborating by sharing knowledge and skills.
  • Willingness to travel to client locations across the UK.
