Star Catcher Industries, Inc., located in
Jacksonville, Florida, has an opportunity for an
Electrical Engineer - Power Electronics to support the development of space-to-space power beaming spacecraft and the Star Catcher Network, its orbital power grid.
Key Responsibilities- Design, architect, and/or execute power electronics circuits; including high-power DC-DC converters, regulators, and power conditioning systems and/or low-voltage power supplies for FPGA/digital electronics, RF, and other mixed-signal cards.
- Design and develop isolated and non-isolated power conversion topologies including AC/DC converters, DC/DC converters, battery chargers, and power management circuits.
- Conduct component selection and design trade studies for power semiconductors, magnetics, ICs, filters, and protection circuitry.
- Simulate and analyze power circuits for efficiency, thermal performance, control loop stability, EMI/EMC, and transient response.
- Support schematic capture, PCB layout, and thermal/EMI analysis for power electronics hardware, ensuring good design practices for high-current, high-voltage, and low-noise applications.
- Build and test breadboard/prototype power hardware through EMI/EMC, TVAC, and vibration qualification.
- Create and execute test plans for prototype bring-up, characterization, verification, and qualification of power electronics hardware.
- Troubleshoot power supply performance issues in the lab and support root cause and corrective action activities.
- Support component selection and qualification for high-reliability, radiation-tolerant power hardware.
- Prepare technical documentation including design reports, analysis summaries, test procedures, and released engineering data.
Basic Qualifications- Education: Bachelor's degree in Electrical Engineering or a related technical discipline.
- Experience: 5+ years of professional experience in power electronics design, ideally with high-power or high-current regulators and power conditioning systems.
- Exposure to architecting power designs from requirements.
Technical Expertise- Working knowledge of switching power supply topologies (e.g., buck, boost, forward, flyback, full-bridge).
- Familiarity with high-voltage design considerations for space, including creepage and clearance standards.
- Experience with schematic capture and PCB layout using EDA tools (e.g., Altium Designer or equivalent).
- Working knowledge of thermal management, EMI/EMC, and grounding practices in power systems.
- Hands-on power-hardware debugging using oscilloscopes, current probes, appropriately rated high-voltage differential probes, electronic loads, and frequency response analyzers or equivalent tools.
- Comfortable both architecting power solutions independently and executing under an established architecture, depending on project needs, in a fast-paced environment.
Desired Skills- Exposure to satellite EPS architecture, battery management systems, or solar array regulators.
- Experience with high-power laser, directed energy, or optical payload power supplies.
- Experience testing or qualifying hardware in thermal-vacuum (TVAC) chambers.
- Familiarity with aerospace testing/qualification standards (MIL-STD-461, MIL-STD-810, NASA GEVS, IPC J-STD-001 Space Addendum).
- Experience designing low-voltage power supplies for digital/FPGA or RF electronics cards.
