• Reverse engineer compiled software, firmware, and proprietary protocols to understand functionality, identify weaknesses, and assess technical feasibility.
• Develop proof-of-concept implementations and mature validated research into documented, testable capabilities.
• Write and debug software
• Analyze platform internals, including memory management, process execution, system calls, access controls, and interprocess communication.
• Build development and testing environments that reproduce relevant system configurations and support repeatable evaluation.
• Develop modular components with clearly defined interfaces to support integration, maintenance, and adaptation to changing requirements.
• Collaborate with independent testing and quality assurance personnel to validate functionality, reliability, compatibility, and failure handling.
• Participate in code reviews, configuration management, and technical planning
• Document software architecture, research findings, build procedures, dependencies, limitations, and test results.

Required Qualifications

• Professional experience in systems programming, reverse engineering, vulnerability research, or closely related software development.
