Role Overview

You will build and operate red team infrastructure, assess external attack surfaces, pivot inside networks, pressure-test detection and response, and conduct penetration tests across diverse targets. The role is suited to builders and operators who think in attack chains and automate repetitive work.

Key Responsibilities

  • Plan and execute advanced red team operations, including adversary emulation and scenario-based testing.
  • Develop and maintain custom tooling for offensive security operations.
  • Perform vulnerability assessments, exploit development, and post-exploitation activities across diverse environments.
  • Conduct reconnaissance, initial access, lateral movement, and persistence techniques using C2 frameworks.
  • Analyze and reverse engineer applications, binaries, and protocols.
  • Collaborate with blue teams to improve detection and response capabilities.
  • Research and publish technical blog articles, CVEs, and open-source tools.
  • Participate in CTFs and bug bounty programs and contribute to the security community.
  • Share knowledge across teams and mentor junior engineers.

Required Skills & Experience

  • Penetration testing and red teaming experience.
  • Solid background in system administration and software development.
  • Deep understanding of vulnerabilities and exploitation techniques.
  • Proficiency in at least one programming language, such as Python, C/C++, or Go.
  • Experience with BurpSuite, Nmap, Nessus, and other scanning tools.
  • Experience with cloud environments including AWS, Azure, and GCP.
  • Experience with Active Directory and Entra ID.
  • Familiarity with networking fundamentals and Windows and Linux operating systems.
  • Strong communication and documentation skills.

Preferred Qualifications

  • Experience in incident response and threat hunting.
  • Certifications such as OSCP, CRTO, CRTL, OSEP, OSWE, OSED, CPTS, CAPE, CWES, or CISSP.
  • Contributions to CVEs or security research.

What We Offer

  • Work in a dynamic, international environment.
