What to Expect
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.
What You'll Do
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.
What You'll Bring
5+ years' relevant work experience post BA, 2+ years' relevant work
experience post MA
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.
Experience bringing products to market which require international
regulatory and safety certifications.
Previous work in the solar, energy storage, electric vehicle, or electric
vehicle charging industry.
Basic understanding of mechanical design fundamentals.
