Seeking Senior IOS Vulnerability Researcher for Raytheon Cyber Security Innovations (CSI) at Dulles, VA. Candidates will analyze mobile devices to understand how they work and how they behave when broken. Candidates must play both sides of the fence in developing and defeating advanced security techniques. Projects are undertaken in small teams with close coordination with customers. All of our engineers write code, but many spend as much time taking systems apart as building them. A typical day may involve studying disassembly or writing Python to audit Swift, Objective-C, or C/C++ code.
We refuse any work that isn’t hard and engaging, we ensure our engineers have the tools they need to do their jobs, and we focus on recognizing results. Our research and development projects cover the spectrum of security technologies for computer network operations. If it runs code, somebody in our office has looked at it.
