Through unrivaled collaboration and unwavering trust, we push the boundaries of what’s possible to empower our team and support our customers in building a safer global future. Overview of Opportunity Two Six Technologies is seeking a Lead CNO Developer to join our Trusted Electronics and Effects 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. As a Lead CNO Developer, you will serve as the technical lead for a small, highly skilled team of developers and researchers. You will provide hands-on technical direction, assign and prioritize tasking, ensure high technical standards, and engage directly with mission partners and stakeholders. You will play a central role in translating research discoveries into scalable, mission-ready cyber capabilities.
