You will be the bridge between traditional expert hacking and our autonomous AI swarm, ensuring our platform reflects the most cutting-edge adversarial tradecraft.

What You’ll Do

• Lead deep-dive penetration tests on Web Applications and APIs, identifying critical vulnerabilities and demonstrating their real-world impact.
• Work closely with our AI research and engineering teams to integrate offensive methodologies into our "AI Swarm" architecture, providing the human-in-the-loop oversight that ensures accuracy.
• Research and develop new exploitation techniques to keep our platform ahead of emerging threats and unique business logic risks.
• Translate technical vulnerabilities into clear, high-quality security reports that provide actionable remediation guidance for our customers.
• Maintain exceptionally high quality control standards, ensuring that our AI-driven assessments meet the rigorous technical benchmarks required by modern enterprises.

Requirements

• 1-2+ years of hands-on experience in Web Application and API Penetration Testing.
• Strong understanding of common attack methodologies, exploitation techniques, and the OWASP Top 10.
• Deep knowledge of networking protocols (TCP/HTTP) and both client-side and server-side languages.
• Practical expertise with Burp Suite, Caido, and other widely used security testing utilities.
• Exceptional skills in writing clear, high-quality security reports, including technical findings and actionable remediation guidance.
• High-level English proficiency—fluent in reading, writing, and speaking.
