Job description

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 Principal Electrical Design Engineer, you will design and validate the digital and mixed‑signal electronics that support Array’s radar payloads and satellite platforms. Your work will include high‑speed digital interfaces, precision clocking and timing distribution, power regulation and control circuits, system monitoring and telemetry hardware, and fault‑tolerant satellite avionics. You will take hardware through design, prototyping, bring‑up, and qualification, working closely with RF, antenna, mechanical, and systems engineers. The hardware you develop will directly affect system performance, power efficiency, stability, and overall reliability on orbit.

• Develop advanced electronic platforms, from architecture to manufacturing
• Work closely with software, firmware, RF, antenna, digital, and mechanical design engineers to design and validate state‑of‑the‑art spacecraft electronics
• Create requirements, perform system trades, select components, capture schematics, design complex electronic assemblies and manage manufacturing
• Lead prototyping, hardware bring‑up, debug, manufacturing, and test campaigns
• Rapidly iterate on and improve electronic designs based on laboratory, environmental and on‑orbit testing
• Provide technical leadership through design reviews, risk reduction planning, and mentorship of early‑career engineers
• B.S. in Electrical Engineering, or a related field with 15+ 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 in electrical engineering, or a related field
• Hands‑on experience with full‑life cycle hardware development (concept to production) in consumer electronics, power electronics, communications, automotive, aerospace, and/or robotics
• Background in high‑speed board design, simulation, and validation techniques including PCB stack‑up, fabrication considerations, layout constraints, component selection, and measurement
• Background in electromagnetic theory and RF fundamentals such as S‑parameters, transmission lines, and broadband impedance matching
• Hands‑on experience designing high‑performance platforms including compute (SoCs, FPGAs, MCUs), storage (DDR, SSDs), high‑speed interfaces (PCIe, SPI, JESD204B), RF components (PAs, LNAs, switches)
• Proficiency with schematic capture and design using CAD tools such as Altium Designer (preferred); experience with Allegro and/or OrCAD is a plus
• Experience with EMC requirements and EMI mitigation techniques
• Experience with signal and power integrity simulation and measurement
• Experience with EM and thermal simulation of printed circuit boards
• Experience with analysis and simulation tools such as LTspice, ADS, and/or Microwave Office
• Experience with data analysis and programming in MATLAB or Python
• Hands‑on experience with test equipment such as oscilloscopes and network analyzers
• 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
