Hands-on experience with modern tools for static/dynamic code analysis, fuzz testing, sanitizers, and secure coding frameworks.
Comfortable using both Linux and Windows operating systems (including command line) for daily software development tasks.
Solid understanding of software development methodologies (i.e. Waterfall, Agile/SCRUM, etc.)
Familiarity with software configuration management tools (i.e. Git, Perforce, ClearCase, etc.)
Active DoD Secret clearance (minimum) and the ability to work onsite in a secure facility.
Background in high-assurance or safety-critical systems (e.g., avionics, defense)
Proficiency with Makefiles and embedded build tools (e.g., cross-compilers, linkers, debuggers).
Experience in integrating and debugging software on embedded targets, including the use of JTAG and hardware/software debug tools.
Experience developing low-level device drivers and interfaces that interact with FPGAs using memory-mapped registers, interrupts, and related techniques.
