If you are an individual with strong hands‑on expertise in offensive security, who can independently lead complex engagements, mentor junior consultants, and act as a trusted technical advisor to clients - this is for you!

You would have deep experience in vulnerability assessment and penetration testing (VAPT), adversarial techniques, and real‑world exploitation across network, web, and enterprise environments, with the ability to translate technical findings into meaningful risk narratives and actionable remediation guidance.

Responsibilities:

• Lead and execute end-to-end offensive security engagements, including network, web application, mobile application, and infrastructure penetration testing.
• Validate and exploit identified vulnerabilities to demonstrate real-world impact and business risk, while producing high-quality technical and executive-level reports with clear risk narratives and actionable remediation recommendations.
• Serve as a technical or project lead during engagements, providing guidance, mentorship, and quality assurance to junior consultants.
• Act as a key technical point of contact for clients, including walkthroughs of findings and remediation discussions.
• Contribute to the development and improvement of internal testing methodologies, tools, and playbooks, and stay current with emerging threats, exploitation techniques, and offensive security research.
• Support pre‑sales and scoping activities by providing technical input when required.

Requirements:

• Minimum 5 years of hands‑on experience in offensive security, penetration testing, or red teaming
• Mandatory Certifications: OSCP, CRT, and OSWE
• Strong understanding of network protocols, operating systems, Active Directory environments, and web application architectures
• Deep knowledge of common attack techniques, vulnerabilities, and frameworks such as OWASP Top 10, MITRE ATT&CK, and CWE
• High proficiency with industry-standard offensive security tools and comfort with custom scripting and automation
• Strong analytical mindset with the ability to think like an attacker and chain multiple weaknesses together
• Excellent written and verbal communication skills, particularly in explaining technical risk to non-technical stakeholders
