Two Six Technologies is seeking a Senior 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.
