• Identify and exploit vulnerabilities including OWASP Top 10, OWASP API Security Top 10, authentication and authorization flaws, business logic vulnerabilities, insecure configurations, privilege escalation, and infrastructure weaknesses.
  
• Perform internal and external network penetration testing, Active Directory assessments, wireless security testing, and cloud security assessments across AWS, Microsoft Azure, and Google Cloud Platform.
  
• Execute Red Team assessments, adversary emulation exercises, and attack simulations where required.
  
• Validate and prioritize vulnerabilities based on business impact, exploitability, and risk.
  
• Prepare detailed technical reports, executive summaries, proof-of-concept documentation, and actionable remediation recommendations.
  
• Support clients in vulnerability remediation by performing re-validation testing and security consultations.
  
• Mentor junior penetration testers and contribute to the continuous improvement of internal methodologies, tools, automation scripts, and offensive security playbooks.
  
• Stay updated on emerging cyber threats, attack techniques, exploit research, and security vulnerabilities to continuously enhance testing methodologies.
  
• Collaborate with cross-functional teams to improve secure development practices, strengthen security controls, and enhance clients' overall cybersecurity resilience.
  

Requirements

• 3–6+ years of experience in Penetration Testing, Vulnerability Assessment (VAPT), Offensive Security, Red Teaming, or Cybersecurity Consulting.
  
• Strong hands-on experience in web application, API, mobile application, network, cloud, and infrastructure penetration testing.
  
• Deep understanding of OWASP Top 10, OWASP API Security Top 10, MITRE ATT&CK Framework, PTES, NIST SP 800-115, and common penetration testing methodologies.
  
• Hands-on experience with offensive security tools such as Burp Suite Professional, Metasploit, Nmap, Nessus, Wireshark, SQLMap, BloodHound, Impacket, Nuclei, Kali Linux, and similar tools.
  
• Experience conducting security assessments across AWS, Microsoft Azure, and Google Cloud Platform.
  
• Strong understanding of networking protocols, Windows and Linux security, Active Directory, authentication mechanisms, and secure application architecture.
  
• Experience preparing technical penetration testing reports, executive summaries, and remediation guidance for clients.
