Linux subsystems, Real‑time operating systems, and bare‑metal design.
Integrating with open‑source applications.
Deep proficiency in C and C++.
Configuration and control of Radio Frequency Receive and Transmit front ends, and transceiver control.
Embedded system security including secure boot, tamper detection, secure SW upgrade, key management, user authentication and encryption, networking security protocols.
Power efficient design including working with multi‑power domain systems, voltage and frequency scaling, and system thermal management.
Efficient, high data throughput systems, DMA, minimum copy systems, and overload control.
Run time diagnostics, BIT, and logging across multiple radio subsystems.
Distributed revision control systems and common embedded Linux development tools (compilers, linkers, and debuggers).
Strong written and verbal communication skills.
Physical demands
Able to frequently sit, stand, walk, use hands to fingers, handle or feel, reach within hand and arm's length, stoop, kneel, and crouch, talk and hear.
Regularly required to sit for extended periods of time; frequently required to use office equipment such as PC, printer, telephone, etc.
Able to regularly lift and/or move up to 10 pounds, frequently lift and/or move up to 25 pounds, and occasionally lift and/or move up to 50 pounds.
