RF Design Engineer

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.

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.

• 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

• 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

• 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
