Department Overview
Accessory & Energy Department responsible for developing communication devices & accessories for the professional and mission critical markets in the commercial, government and industrial segments
Job Description
Key Responsibilities
- Firmware Development: Write, test, and optimize C/C++ code for bare-metal microcontroller environments.
- Protocol Implementation: Develop and test low-level driver code to establish reliable communication between the MCU and peripheral ICs using I2C and 1-Wire protocols.
- Hardware Bring-Up & Testing: Assist in bringing up new custom prototype boards, verifying correct pin mappings, voltage levels, and clock configurations.
- System Debugging: Isolate and resolve complex hardware-software integration issues using a combination of firmware stepping and physical measurement tools.
- Documentation: Document driver logic, API usage, and hardware test results for the broader engineering team.
Basic Requirements
- Microcontroller (MCU) Fundamentals: Strong understanding of MCU architecture, including GPIO configuration, interrupt service routines (ISRs), timers, ADCs, and memory constraints.
- Embedded C/C++: Proficiency in writing efficient, hardware-level C or C++ code. Bitwise operations and pointer manipulation should be second nature.
- Serial Communication Protocols: Solid theoretical understanding and practical experience with I2C (addressing, clock stretching, pull-up resistor sizing, ACK/NACK behavior).Familiarity with the 1-Wire bus protocol (timing constraints, presence pulses, ROM commands).
- Hardware Debugging Skills: Hands-on experience using hardware diagnostic tools such as:Logic analyzers (to decode I2C/1-Wire bus traffic and verify timing requirements).Oscilloscopes (to check signal integrity, capacitance issues, and rise/fall times).Multimeters and JTAG debuggers.
- Education: Currently pursuing or recently completed a B.S. or M.S. in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
