Senior RF Design Engineer
Array Labs, Redwood City, CA, United States
Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.
We’re launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth – updated in real time – enabling faster, smarter decision‑making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission‑critical geopolitical intelligence.
We design and build our satellites end‑to‑end, producing the world’s most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they’re needed most.
About the Job
As a Senior 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.
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
Basic Qualifications
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
Preferred Skills and Experience
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
$150,000 - $170,000 a year
ITAR Requirements
To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Interview Process
We will conduct three interviews via Zoom; the typical process takes around 3-5 weeks to complete from start to finish.
Hiring and Compensation Strategy
Our hiring and compensation strategy is simple:
1) find uncommonly good people
2) pay them uncommonly well
You can anticipate competitive pay, generous equity, and high flexibility between salary and equity-based compensation.
Why Join Array
At Array Labs, deep technical expertise meets relentless impact. We prioritize curiosity over hierarchy and bold engineering over incremental gains. Our world‑class team across hardware engineering, software, and aerospace works collaboratively to push boundaries and move fast.
Our values:
1. Build What Matters: Create technology that serves customers and advances humanity
2. Innovate Together: Stay curious, collaborate openly, push boundaries as one team
