  • Perform board bring-up and debug to optimize embedded SW/HW on bench and in real-world conditions.
  • Work closely with hardware test engineers to develop hardware validation test plans and EOL test systems.
  • Work closely with software test engineers to develop software validation test plans.
  • Maintain existing products by performing SW/HW root cause analysis and component EOL/substitutions.
  • Facilitate production validation testing by travelling to 3rd party test labs.
  • Research new technologies to integrate into future products.
REQUIRED SKILLS/QUALIFICATIONS:
  • Minimum 3 years of relevant experience.
  • Bachelor's in Electrical, Software, Computer Engineering or equivalent discipline.
  • Experience in performing complex mixed signal schematic and PCB designs (6-layer min).
  • Strong proficiency in writing and debugging C code on 32-bit microcontrollers.
  • Understanding of signal integrity and simulation tools such as Tina, LTSpice, and PSPICE.
  • Experience with routing high speed buses such as SPI, A2B, CAN, USB, etc.
  • Knowledge of EMC/EMI best practices as well as mitigation techniques.
  • Strong experience with analog audio circuits such as active and passive filter design, preamps, buffers, etc.
  • Knowledge of power supply topologies such as buck, boost, and inverters.
  • Experiencing using audio data converters (ADC's, DAC's, and CODEC's ) in designs.
  • Experience using microcontrollers and digital signal processors in designs.
  • Experience with bootloaders, linker files, and toolchains (GNU, IAR, etc.).
  • Ability to troubleshoot hardware using logic analyzers, oscilloscopes, and spectrum analyzers.
  • Experience debugging C source code using hardware debuggers over JTAG and SWD.
  • Attention to detail and appreciation for good code architecture and documentation.
  • Experience with full product development lifecycle for all stages from conception through volume
manufacturing.
  • Experience coordinating with external contract manufacturers and overseeing prototype/production builds, including hands-on work when needed.
  • Occasional travel to contract manufacturers facilities in Asia.
  • Must be able to solder and rework fine pitch components.
  • Strong team player with positive attitude and willingness to learn and collaborate in group settings.
DESIRED SKILLS (OPTIONAL):
  • System level audio design including knowledge of infotainment, audio amplification, transducers, and vehicle tuning.
  • Experience with automotive CAN bus (ISO-11898, ISO-11783, J1939, NMEA2K, ISO-15765, ISO-14229).
  • Experience with Bluetooth Low Energy (L2CAP, GATT).
  • Familiarity with product/technology/certifications (e.g. Bluetooth classic and Bluetooth Low Energy).
  • Knowledge of basic DSP building blocks for audio processing (FIR, IIR, FFT, etc.).
  • Experience with embedded graphical HMI design.
  • Experience with Linux, QNX or Android based embedded operating systems.
  • Knowledge of creating scripts or programs using languages such Python, JS, C#, or LabVIEW.
