Staff RF Design Engineer

Array Labs • Palo Alto, CA

1d • $170,000 - $220,000

About The Position

As a Staff RF Design Engineer, you will design and validate the RF electronics that enable Array’s radar sensors. Your work will include low-noise receive chains, high-power transmit chains, RF switching and protection, bias and control circuitry, and integration of transceiver and timing-critical RF subsystems.
You will take hardware from schematic design through prototyping, bring-up, characterization, and qualification, working closely with antenna, mixed-signal, mechanical, and systems engineers. The RF hardware you develop will directly impact signal quality, sensitivity, output power, stability, and overall on-orbit performance.

Requirements

• B.S. in Electrical Engineering, or a related field with 4-7 years of relevant experience
• Experience in electronics design, bring-up, and test
• Excellent teamwork and communication skills
• Learns new concepts rapidly, completely, and in a self-directed manner
• High levels of self-motivation and personal accountability
• Ability to work in a fast-paced environment under significant time constraints

Nice To Haves

• Master’s degree or Ph.D. in electrical engineering, applied physics, or a related field
• Strong background in electromagnetic theory and RF fundamentals such as S-parameters, transmission lines, stability analysis, and impedance matching
• Hands-on experience designing high-performance RF hardware including LNAs, PAs/driver chains, mixers, switches, filters, couplers, and protection circuitry
• Experience with frequency synthesis and timing-critical RF subsystems including PLLs, VCOs, references, and low-jitter clock distribution
• Experience with RF modeling, simulation, and analysis tools such as ADS, Microwave Office, and/or HFSS
• Experience with schematic capture and design using CAD tools such as Altium Designer (preferred); experience with Allegro and/or OrCAD is a plus
• Hands-on experience with RF test and characterization equipment such as VNAs, spectrum analyzers, signal generators, power meters, and phase noise measurement
• Experience with EMC requirements and EMI mitigation techniques in mixed-signal and RF systems
• Experience taking RF hardware from prototype through qualification and environmental testing, including working with manufacturing partners and test teams

Responsibilities

• Develop advanced RF electronic subsystems, from architecture to manufacturing
• Work closely with RF systems, antenna, mixed-signal, mechanical, firmware, and test engineers to design and validate state-of-the-art radar sensor hardware
• Own RF subsystem definition and design trade studies, balancing noise figure, linearity, output power, stability, spurious performance, and power consumption
• Select components, capture schematics, and design complex RF assemblies including receive and transmit chains, switching networks, filtering, and protection circuitry
• Lead prototyping, hardware bring-up, debug, characterization, and test campaigns for RF electronics
• Rapidly iterate on and improve RF designs based on laboratory and environmental testing
• Provide technical leadership through design reviews, risk reduction planning, and mentorship of other engineers
