Job Summary

We are seeking a Senior Penetration Tester / Red Team Engineer to support offensive security initiatives through advanced penetration testing, red team operations, and custom security tool development. This role combines hands-on security engineering with offensive security expertise to identify vulnerabilities, simulate real-world attack scenarios, and develop automation solutions that enhance security assessment capabilities.

*Please note, this role is not able to offer visa transfer or sponsorship now or in the future*

In this role, you will:

· Design and develop custom security tools, automation frameworks, and scripts to support penetration testing and red team operations.

· Conduct comprehensive penetration testing of web applications, APIs, cloud platforms, networks, and enterprise infrastructure.

· Participate in red team engagements that emulate real-world adversaries to evaluate organizational security defenses.

· Identify, validate, and document vulnerabilities, attack paths, and security weaknesses with actionable remediation recommendations.

· Build integrations between security tools, enterprise platforms, and automation workflows to improve testing efficiency and coverage.

· 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.

· Excellent analytical, troubleshooting, documentation, and communication skills.

· Security certifications such as OSCP, CRTO, PNPT, GPEN, CEH, or equivalent are highly desirable.
