The Residential Hardware Design team is responsible for developing and maintaining home energy storage and vehicle charging solutions to use clean energy to make sure homes are always powered and vehicles are always ready to drive regardless of what is happening in the outside world. This skilled and motivated individual will keep pushing this evolving industry forward by designing wireless communication systems primarily but also circuits to ensure user safety, energy metering, thermal controls, relay controls for grid connection, and much more.
Responsibilities
Design and develop digital electronics, analog electronics, and small power supplies for wireless systems in energy products.
Collaborative work with mechanical, firmware, EMC, RF, design validation, thermal design, compliance, reliability, and manufacturing test engineers.
Start to finish ownership of circuit board electronics – from specification through design, prototype, validation, manufacturing and sustaining.
Required Skills
BS or higher degree in Electrical Engineering (MSEE preferred).
3-5 years relevant work experience.
Experience implementing wireless communication systems (cellular, Wi-Fi, Bluetooth, power line communications, etc.).
Deep understanding of at least one wireless technology.
Familiarity with key RF performance (e.g. power, sensitivity, throughput, latency and etc) and system validation methodology.
Experience in supervision of PCB layout, plane definition, and EMC / Desense / Co-existence optimization.
Experience designing digital communication busses (CAN, Ethernet, RS-485, USB, SPI, I2C, MII, PCIe etc.).
Experience in selection and use of DSPs, microcontrollers, memory, and programmable logic devices.
Experience in selection and use of analog sensors and signal conditioning circuits.
Experience designing board level power supplies (buck, boost, flyback, etc.).
Proficiency with basic EE tools and RF testers (scopes, network analyzers, spectrum analyzer, signal generator and etc.).
Medium to high volume DFT and DFM.
Preferred Skills
5+ years relevant work experience.
Experience with design, selection and validation of wireless modules and antennas for wireless technologies.
Experience with translating system performance specifications into hardware specifications.
Understanding of PHY Layer and MAC/application layer is a plus.
Proficiency at MATLAB simulations to model and analyze wireless feature implementations is a plus.
Proficiency at HFSS simulations to model/analyze wireless HW issues is also a plus.
Embedded programming of DSPs, microcontrollers, and programmable logic devices.
Experience working on high voltage, high power systems.
