Firmware-Savvy CNO Developer

Must be a US Citizen MUST HAVE AN ACTIVE TS/SCI with Full Scope Poly Clearance

Our client conducts R&D and prototyping of new CNO capabilities for the end customer. The work involves Vulnerability Research, Exploit Development, CNO tool development and enhancement, and infrastructure support (Dev Ops). Platforms involved include iOS, Android, MacOS, Linux, Windows, and other environments. This is some of the most impactful work in the Intelligence Community, with the new capabilities developed by this team getting rapidly deployed and into the hands of users.

One of the best things about this project is the customer. They give Engineers huge latitude in choosing programming languages and technologies, and they encourage exploration of new tech. There is almost no distinction here between blue-badgers and green-badgers: the team is highly-competent, and the Branch and Section Leads do an excellent job of shielding the engineers from any organizational politics.

We are seeking a highly skilled Firmware-Savvy CNO Developer to join the Firmware team to support mission-critical cyber operations and development of new and existing capabilities. The ideal candidate will have a strong foundation in low-level systems programming, embedded development, and Windows internals, with a passion for solving complex technical challenges in secure and virtualized environments.

Work on this program takes place in various locations at and around the Annapolis Junction, MD area (we cannot support remote work).
