Description
Senior Power Electronics Engineer
Team: Engineering
Location: Palo Alto, CA
Commitment: Full-Time
Workplace Type: onsite
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 Power Electronics Engineer, you will design and validate the power conversion and power management electronics that enable Array’s radar sensors and satellite platforms. Your work will include high-efficiency DC/DC conversion, power distribution, sequencing, monitoring and telemetry, protection and fault handling, and the power interfaces that support high-power RF operation.
You will take hardware from schematic design through prototyping, bring-up, characterization, and qualification, working closely with RF, mixed-signal, mechanical, firmware, and systems engineers. The power electronics you develop will directly impact system efficiency, thermal performance, reliability, and on-orbit availability.
Responsibilities:
- Develop advanced power electronics subsystems, from architecture to manufacturing
- Own power subsystem definition and design trade studies, balancing efficiency, transient performance, thermal behavior, and fault tolerance
- Select components, capture schematics, and design complex power assemblies including DC/DC conversion, sequencing, protection, and monitoring
- Lead prototyping, hardware bring-up, debug, characterization, qualification, and test efforts for power electronics
- Work closely with RF, mixed-signal, mechanical, firmware, and systems engineers to deliver reliable radar sensor and spacecraft power systems
Basic Qualifications:
- B.S. in Electrical Engineering, or a related field with 4+ 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, power electronics, or a related field
- Hands-on experience designing high-efficiency power conversion systems including synchronous buck/boost, isolated converters, and multi-rail power architectures
- Experience with power management and protection circuitry including hot-swap, eFuses, current limiting, OR-ing, inrush control, and fault detection
- Strong background in power integrity, transient response, stability/compensation, and low-noise rail design for mixed-signal and RF systems
- Experience with battery interfacing, peak-power buffering, and pulsed-load power delivery for high-power electronics
- Experience with analysis and simulation tools such as LTspice, SIMPLIS, and/or MATLAB
- Proficiency with schematic capture and design using Altium Designer (preferred); experience with Allegro and/or OrCAD is a plus
- Hands-on experience with test and characterization equipment such as oscilloscopes, electronic loads, power analyzers, and current probes
- Experience taking power electronics hardware from prototype through qualification and environmental testing, including working with manufacturing partners and test teams
- Experience with EMC requirements and EMI mitigation techniques in power electronics systems
