Since I'm not really sure that a developer that exactly fits your requirement would be quicly found, just in case I offer my skills.
I've about 15 years in software development (C/C++, system development, sciencific HW development, etc.) I believe I can become a specialist in any area around computers.
On the other hand, I'd never heard about VxWorks and BSPs :)
: Responsible for developing low level embedded drivers and tools to support a common environment used on PowerPC and the other microprocessor designs. Includes responsibility for research, design, development, debug, test and documentation.
: VxWorks expertise with experience writing BSPs is a strong asset!
