Staff RF Design Engineer

Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.\u00a0\n\nWe’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.\n\nWe 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.\n\nAbout the Job\n\nAs 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.\n\nYou 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.\n\n### Responsibilities:\n* Develop advanced RF electronic subsystems, from architecture to manufacturing\n* Work closely with RF systems, antenna, mixed-signal, mechanical, firmware, and test engineers to design and validate state-of-the-art radar sensor hardware\n* Own RF subsystem definition and design trade studies, balancing noise figure, linearity, output power, stability, spurious performance, and power consumption\n* Select components, capture schematics, and design complex RF assemblies including receive and transmit chains, switching networks, filtering, and protection circuitry\n* Lead prototyping, hardware bring-up, debug, characterization, and test campaigns for RF electronics\n* Rapidly iterate on and improve RF designs based on laboratory and environmental testing\n* Provide technical leadership through design reviews, risk reduction planning, and mentorship of other engineers\n\n### Basic Qualifications:\n* B.S. in Electrical Engineering, or a related field with 4-7 years of relevant experience\n* Experience in electronics design, bring-up, and test\n* Excellent teamwork and communication skills\n* Learns new concepts rapidly, completely, and in a self-directed manner\n* High levels of self-motivation and personal accountability\n* Ability to work in a fast-paced environment under significant time constraints\n\n### Preferred Skills and Experience:\n* Master’s degree or Ph.D. in electrical engineering, applied physics, or a related field\n* Strong background in electromagnetic theory and RF fundamentals such as S-parameters, transmission lines, stability analysis, and impedance matching\n* Hands-on experience designing high-performance RF hardware including LNAs, PAs/driver chains, mixers, switches, filters, couplers, and protection circuitry\n* Experience with frequency synthesis and timing-critical RF subsystems including PLLs, VCOs, references, and low-jitter clock distribution\n* Experience with RF modeling, simulation, and analysis tools such as ADS, Microwave Office, and/or HFSS\n* Experience with schematic capture and design using CAD tools such as Altium Designer (preferred); experience with Allegro and/or OrCAD is a plus\n* Hands-on experience with RF test and characterization equipment such as VNAs, spectrum analyzers, signal generators, power meters, and phase noise measurement\n* Experience with EMC requirements and EMI mitigation techniques in mixed-signal and RF systems\n* Experience taking RF hardware from prototype through qualification and environmental testing, including working with manufacturing partners and test teams\n\nUSD 170,000 - 220,000 a year
