Software Developer

Responsibilities: Responsible for developing, testing, and sustaining cybersecurity tools used to analyze protocol and service vulnerabilities, build proof-of-concept exploits, and tailor Command and Control (C2) capabilities in representative environments. Perform software development across the full lifecycle—including requirements gathering, design, coding, testing, deployment, and maintenance—using Agile and DevSecOps methodologies. Leverage version control systems, code analysis tools, and debugging techniques. Implement STIGs, work with communication protocols such as DNS, HTTP/S, WebSockets, and SMB, and develop software and automation using languages including Python, C/C++, C#, Go, Rust, and Assembly. Utilize containerization technologies such as Docker and software virtual environments (e.g., PyEnv) to support secure, scalable, and repeatable development and testing workflows while ensuring compliance with established tool development lifecycle requirements.

Required Knowledge, Skills and Abilities (KSA): Demonstrated experience with the full software development lifecycle (SDLC), including requirements gathering, design, development, testing, deployment, sustainment, and maintenance using Agile, DevSecOps, or similar methodologies.
