Company

hirify.global is developing Keystar, an orbital power plant project, with a founding team connected to NASA, Blue Origin, SpaceX, and the ISS.

What you will do

• Own the electrical power subsystem for the Keystar spacecraft, including power generation, conditioning, distribution, and battery systems.
• Establish the high-voltage PMAD architecture, set technical parameters, evaluate tradeoffs, manage margins and risks, and develop PCDU and EMI-filtering solutions.
• Design high-voltage systems for reliable operation in vacuum, accounting for electrical breakdown, corona discharge, insulation, and component derating.
• Develop, test, and document prototypes, engineering models, and flight hardware, including schematics, PCB layouts, and manufacturing documentation.
• Build and debug hardware through breadboarding, PCB assembly, bench testing, and rapid prototyping; establish board bring-up processes and electrical design standards.
• Lead design-for-manufacturing reviews and guide hardware through production, Assembly, Integration, & Test, environmental qualification, reuse, and requalification.

Requirements

• 6+ years of experience in electrical design and circuit analysis for spacecraft.
• Direct experience with spacecraft power systems, including solar arrays, PCDUs, battery management systems, or high-voltage power distribution.
• Strong experience with schematic capture, PCB layout, and circuit design.
• In-depth knowledge of power electronics, including DC-DC conversion, power distribution, battery management, and switching efficiency.
• Experience designing or qualifying high-voltage power electronics, including corona discharge, electrical breakdown in vacuum, insulation, and component derating.
• Strong understanding of analog and digital electronics, component selection, and electrical compatibility.
• Fluency with Design for Manufacturing principles and electronics fabrication and assembly.
• Hands-on experience with rapid prototyping and hardware testing, including breadboarding, PCB assembly, bench testing, and debugging.
• Proficiency with electronic design and analysis tools such as Altium, KiCad, SPICE, or equivalent.
• Familiarity with radiation, thermal-vacuum testing, electromagnetic compatibility, and relevant spacecraft power, high-voltage, environmental-testing, and EMI/EMC standards.
• Experience taking hardware through formal design reviews and qualification under configuration control.
• Flexible, resourceful, and decisive, with the ability to evaluate tradeoffs, manage risk, and make sound engineering decisions.
• Hands-on approach to building, testing, and iterating physical systems.
• Applicants must be a U.S. Person as defined by export-control regulations or otherwise eligible to access export-controlled information and technology.

Nice to have

• Knowledge of embedded systems, firmware, sensor interfaces, precision measurement, or instrumentation.
• Experience through AI&T and formal design reviews, or experience mentoring junior engineers.
• Startup or early-stage engineering experience.

Culture & Benefits
