· Research and develop offensive security techniques, attack simulations, and proof-of-concept exploits for emerging threats.

· Support security engineering initiatives by solving complex technical challenges requiring both development and cybersecurity expertise.

· Collaborate with development, infrastructure, and security teams to improve security posture and address identified risks.

· Maintain detailed documentation of testing methodologies, findings, tools, and operational procedures.

· Contribute to continuous improvement of penetration testing, red teaming, and security automation capabilities across the organization.

What you need to have to be considered

· 3–5 years of experience in Penetration Testing, Red Teaming, Security Engineering, or Software Development with a strong security focus.

· Strong programming and scripting expertise in languages such as Python, Go, Java, C#, PowerShell, or similar technologies.

· Hands-on experience conducting penetration testing using industry-standard methodologies and frameworks.

· Experience participating in red team engagements and adversary simulation exercises.

· Proficiency with offensive security tools such as Burp Suite, Metasploit, Nmap, Cobalt Strike, BloodHound, or similar platforms.

· Strong understanding of web application security, API security, network security, and cloud security concepts.

· Experience developing custom security tools, automation scripts, or offensive security utilities.

· Familiarity with security frameworks such as MITRE ATT&CK, OWASP Top 10, and penetration testing best practices.
