What are the responsibilities and job description for the Senior Hardware / PCB Design Engineer position at BIOPAC Systems, Inc.?
We are seeking an experienced Hardware / PCB Design Engineer to lead the development of complex embedded systems featuring high-speed microprocessors/microcontrollers, FPGAs, DDR memory, Ethernet, WiFi, and Bluetooth.
This position blends high-speed digital design and PCB layout with power-supply engineering and seamlessly interfacing to precision analog circuitry.
Responsibilities
- Design and layout 4 layer PCBs in Altium Designer with BGA processors, DDR memory, and FPGAs.
- Implement controlled impedance routing, differential pairs, and length-matching for DDR and other high-speed signals.
- Perform signal/power integrity analysis and ensure compliance with manufacturer layout guidelines.
- Design low-noise multi-rail power supplies and sequencing for microprocessors, memory, and analog circuits..
- Work as a team with software and firmware developers as well as production and testing staff.
Qualifications
- B.S./M.S. in Electrical Engineering or equivalent.
- 5 years in high-speed PCB design (DDR, USB, Ethernet, LVDS, etc.).
- Strong knowledge of transmission line theory, stack-up design, and EMI/EMC best practices.
- Proficiency with Altium Designer and SI/PI simulation tools (e.g., HyperLynx).
- Experience integrating with analog front ends (low-noise amplifiers, filters, ADC/DAC interfaces).
- Excellent organizational skills and communication skills.
Preferred
- Experience with Microchip SAM9X7 and Xilinx Spartan-7.
- Experience with CODEC integration
- Knowledge of analog circuits (amplifiers and filters)
- Power-supply design for sensitive mixed-signal systems.
This is a full-time position with opportunities for ownership of the entire hardware design process.
