Principal Reverse Engineering/Vulnerability Research Engineer

Location: Herndon, VA

Department: Reverse Engineering / Vulnerability Research

Position Summary

We are seeking a highly skilled Security Researcher who views a black box not as a roadblock, but as an invitation. We need an investigator with an insatiable, demonstrated curiosity for figuring out how software and hardware truly work under the hood—regardless of how they are advertised or intended to function. In this role, you will be on the front lines of vulnerability discovery, dismantling complex systems to expose their flaws. You will frequently operate in the dark, confronting entirely new pieces of software or hardware with zero documentation. Success requires extreme comfort with uncertainty, a hypothesis-driven approach to experimentation, and the engineering chops to build custom utilities when off-the-shelf tools fall short.

You will not be working in a silo. You will push your research to the absolute limit, but you also possess the wisdom to know when to ask for help, share your breakthroughs, and collaborate to drive the broader project forward.
