Penetration Tester

This job is with Capgemini, an inclusive employer and a member of my Gwork – the largest global platform for the LGBTQ+ business community. Please do not contact the recruiter directly.

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.

As a member of this team, you’ll 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.

• Producing accurate, concise documentation including technical reports, executive summaries, scopes, and proposals.

• Maintaining your strong technical expertise and contributing to service development by staying up-to-date with emerging threats, technologies, vulnerabilities and methodologies.
• Sharing your knowledge across the team, participating in research and involving yourself in initiatives which enhance capability.
