• Familiarity with reading firmware source like VHDL or Verilog.
• Familiarity with assembly language in at least one processor/controller family.
• Experience using lab instruments like power supplies, digital multimeters, oscilloscopes, and logic analyzers.
• Experience developing device drivers for bare-metal and/or OS applications.
• Experience leading engineering teams in delivering systems (of various sizes) involving the integration of hardware and software.

Benefits

• Medical, dental, and vision insurance.
• Life insurance, short-term disability, and long-term disability.
