About the role

We're looking for a senior practitioner to lead penetration testing engagements across web applications, internal networks, cloud environments, and OT systems. You will work directly with clients — from scoping calls through to final presentations — and help shape how we deliver assessments. This is a technical and client-facing role in equal measure.

What you'll do

  • Lead end-to-end penetration testing engagements: scoping, reconnaissance, exploitation, post-exploitation, and reporting
  • Conduct web application assessments following OWASP methodology, with a focus on manual testing and business logic
  • Perform network and infrastructure assessments, including Active Directory environments and cloud configurations
  • Produce clear, actionable reports for both technical and executive audiences — without editorial hand-holding
  • Present findings directly to client security and engineering teams
  • Contribute to methodology development, internal tooling, and knowledge sharing across the team
  • Support junior team members on complex engagements

What we're looking for

  • 4+ years conducting penetration tests in a professional services or consultancy environment
  • Strong proficiency with offensive tooling: Burp Suite Pro, Metasploit, Cobalt Strike, custom scripts
  • Solid understanding of Active Directory attack paths, lateral movement, and privilege escalation
  • Experience with web application testing — OWASP Top 10, API security, authentication flaws
  • Ability to write high-quality, client-ready reports independently
  • Professional working level in English; Spanish is an advantage
  • Based in Europe (for client travel when required)

Nice to have

  • OSCP, CRTE, CRTO, CPTS, or equivalent offensive certifications
  • Experience with cloud environments (AWS, Azure, GCP) from an attacker perspective
  • Social engineering or phishing simulation experience
  • Familiarity with OT/SCADA security testing
  • CVEs or public security research

What we offer

  • Fully remote role within Europe, with occasional client travel
  • A technically rigorous team — no padding, no checkbox mentality
  • Exposure to diverse client environments across industries and European jurisdictions
  • Direct impact on engagements from day one — no lengthy onboarding bureaucracy
  • Competitive compensation commensurate with experience
