Job Description & Summary

A career within Cybersecurity and Privacy services at PwC offers the opportunity to work on the frontlines of digital defense, helping clients identify vulnerabilities before adversaries do.

This role focuses on delivering offensive security engagements, both for local clients and in collaboration with PwC teams across the broader Central and Eastern Europe region.

As a Penetration Tester / Adversary Simulation Specialist, you will lead and support offensive security engagements including infrastructure, web application, and cloud penetration testing, as well as red and purple teaming initiatives. You will simulate real-world attack scenarios, identify exploitable weaknesses, and provide actionable guidance to clients seeking to strengthen their defenses.

  • Conduct infrastructure, application, and cloud penetration tests using industry-standard tools and custom scripts.
  • Simulate advanced attack scenarios through red team or assumed breach exercises.
  • Develop and deliver clear, technically accurate findings and remediation guidance to both technical and executive stakeholders.
  • Collaborate with incident response, cloud security, and digital identity teams to integrate offensive insights into broader cyber programs.
  • Stay current on threat actor tactics, techniques, and procedures (TTPs) and continuously evolve testing approaches.
  • Contribute to development of internal toolkits, testing procedures, and service documentation.

Requirements:

  • 3+ years of hands-on experience in penetration testing or offensive security roles.
  • Proficiency in using tools such as Burp Suite, Metasploit, Cobalt Strike, and scripting languages like Python or PowerShell.
  • Understanding of MITRE ATT&CK framework and red/purple team methodologies.
  • Relevant certifications such as OSCP, CRTP, OSCE, or similar are highly desirable.
  • Strong analytical, problem-solving, and communication skills; fluent English required.
