Overview of Opportunity 

Two Six Technologies is seeking a CNO Developer to join our communications systems team supporting an advanced telecommunications research and cyber capability development program. 

This is a full-time, in-office position based in our Arlington, Virginia office, where close collaboration across reverse engineering, vulnerability research, and hardware teams is critical to mission success. 

This program has conducted deep technical research into telecommunications access mechanisms within defined systems, identifying novel methods that enable system access without traditional interaction. The team is now focused on leveraging that research to perform advanced reverse engineering and vulnerability research, as well as to develop operational tools and capabilities that can be deployed in complex, real-world environments. 

In this role, you will work alongside reverse engineers and vulnerability researchers to transform cutting-edge research into mission-ready cyber capabilities. You will be part of a small, highly collaborative team building custom software tools and evolving innovative proofs-of-concept into robust operational solutions.

What You Will Do:

• Design and develop custom tools and software targeting embedded and telecommunications systems under moderate supervision with some latitude for independent judgment.
• Serve as a cyber capability developer on a small, highly motivated team, executing and completing assigned development tasks timely.
• Develop proofs-of-concept from discovered vulnerabilities and transition them into maintainable codebases following DevOps best practices.
• Analyze firmware, software protections, operating system internals, and network protocols to support capability development objectives.
• Collaborate closely with developers, vulnerability researchers, and hardware engineers in a fast-paced environment to produce high-quality deliverables that align with customer mission needs.

What You Will Need (Minimum Qualifications):

• Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline (or equivalent practical experience).
• 2+ years of experience designing and/or prototyping applications using agile software development processes and low-level programming in Python, C, or C++.
• Applied experience with operating system internals (privilege models, binary memory layout) and network socket programming across IP, TCP, and related protocols.
• Practical experience reverse engineering x86/ARM binaries or embedded systems using debuggers (GDB, WinDbg) or disassembly tools (Ghidra, Binary Ninja).
• Active U.S. Top Secret security clearance with ability to obtain and maintain SCI access.

Nice to Have (Preferred Qualifications):

• Familiarity with identifying and analyzing vulnerabilities in complex applications and memory protection mechanisms (ASLR, DEP).
• Experience with CI/CD pipelines, virtualized test ranges, or firmware/driver development across Linux, Windows, or embedded systems.
• Understanding of telecommunications systems, access mechanisms, or 5G infrastructure components.
• Demonstrated ability to learn new methods, keep pace with emerging tools, and apply technical knowledge to deliver high-quality work efficiently.

Clearance Requirements: 

• Active U.S. Security clearance of Top Secret level with the ability to obtain/maintain SCI.
