About The Role \n

We’re seeking a highly skilled Senior Penetration Tester to join Gridware as a full-time resource. You’ll lead and deliver complex, end-to-end security engagements - from traditional penetration tests through to advanced adversary simulations - while playing a critical role in shaping our methodologies, mentoring consultants, and strengthening client relationships.

\n

You’ll work closely with stakeholders, drive innovation within the team, and maintain the standard of excellence Gridware is recognised for across the cybersecurity industry.

What You'll Do \n

    \n
  • Red Team operations (C2 infrastructure, payload development and evasion, physical, and human layers) - highly desirable
    • \n
  • Cloud pen testing and security assessments
    • \n
  • Internal and External Network and host penetration testing
    • \n
  • Web and API assessments
    • \n
  • Mobile application assessments
    • \n
  • Wireless assessments
    • \n
  • Scope and define engagements, attend ROE calls, and manage client expectations throughout the lifecycle of an assessment.
    • \n
  • Present technical findings in a clear, risk-aligned way to both technical and executive stakeholders.
    • \n
  • Deliver high-quality, concise reports with actionable remediation tailored to each client.
    • \n
  • Mentor and coach junior consultants, providing technical direction, peer review, and support in developing methodologies.
    • \n
  • Contribute to proposal writing, pre-sales activities, and the development of new service offerings.
    • \n

What You'll Need \n

    \n
  • At least 3-5 years of offensive security consulting experience, with proven ability to manage and deliver complex engagements.
    • \n
  • Demonstrated resilience and adaptability in responding to challenges and setbacks, maintaining focus and delivering outcomes under pressure.
    • \n
  • Penetration testing certifications such as CRTO, CRTL, OSCP, CPTS, SANS (e.g., GXPN, GWAPT), or CREST CCT (Applications or Infrastructure) - strongly regarded but not essential.
    • \n
  • Strong analytical and problem-solving skills, with the ability to think laterally and apply creative approaches to security challenges.
    • \n
  • Ability to assess applications and infrastructure from both technical and business risk perspectives.
    • \n
  • Experience scripting or developing custom tools to innovate and improve testing efficiency.
    • \n
  • Excellent stakeholder engagement and communication skills, with the ability to influence, simplify, and articulate complex security issues for both technical and non-technical audiences.
    • \n
  • Ability to draft structured, remediation-driven reports aligned to client risk priorities.
    • \n
  • Strong passion for offensive security, with a curious and innovative mindset, and a drive for continuous improvement.
    • \n
  • Eligibility to obtain and hold security clearances.
    • \n
  • Confidence in presenting technical concepts at community-driven events, conferences, or internal knowledge-sharing sessions.
    • \n
