This role includes collaboration with cross-functional teams, driving innovation, and ensuring that all designs meet the highest standards of performance, efficiency, safety and regulatory compliance.

• Contribute to architecture, requirements development and system engineering for new product developments of grid-connected power electronics systems.
• Develop and document module and PC board assembly requirements and functional specifications 
• Develop and document system-level functional specifications, including communications and control architectures.
• Design verification for function and performance with hands-on testing and early simulation. 
• Take development ownership of a circuit board or subsystem, including documentation of requirements and specifications, circuit design and analysis, component selection, schematic capture, layout, firmware requirements, debugging, and leading of design reviews for all stages.
• Serve as the expert and mentor on PCB design best practices and the development process, including tools, libraries, and documentation requirements.
• Co-own with other team leads the processes for revision and configuration management.
• Cross-functional collaboration with mechanical and software engineers during product development.
• Actively participate in documenting company owned Intellectual Property as needed.

• Bachelor’s, and preferably Master’s, Degree in Electrical Engineering.
• 10+ years of experience designing mixed signal (digital/analog) PCB assemblies with microcontrollers, Digital Signal Processors (DSP), ethernet, and serial communications (e.g. CAN, I2C, RS-232) 
• Familiarity with Design for Manufacture & Test (DFM/DFT), Quality, and Reliability concepts 
• Experience with mixed signal (digital/analog) hands-on PCB layout design, and EMC mitigation in high noise environments 
• Experience with board-level power management, including buck and linear regulators. 
• Experience with concept to manufacturing product design cycles, including prototype assembly and testing, both in house and using contract manufacturers 

Experience or familiarity with the following is highly desirable:

• IPC, UL/Safety, and EMC standards. 
• Power electronics topologies and components 
• Electrical distribution grid and AC power distribution 
• Familiarity with system level power management for applications such as energy storage systems, DC Microgrids, and EV charging
• High-speed board design with embedded CPUs
• VHDL/Verilog experience for programming CPLD or FPGA devices 
• Writing C code for microcontrollers and digital signal processors 
• High-voltage and high-power applications, including safety isolation, gate drives, current sensors, magnetic components, and isolated communications 
• Exposure to environmentally hardened Industrial rated product development 
• Knowledge of communication protocols for ethernet/PoE, CAN, I2C and RS-232  
• Battery chemistries, pack design, and battery/energy management systems (BMS/EMS)
