hirify.global develops autonomous spacecraft, advanced payloads, mission software, and space-based interceptors for space defense and space superiority.

What you will do

• Lead the design and development of spacecraft power systems, including solar arrays, batteries, power distribution units, regulation, and protection circuits.
• Own power architecture trades and technical decisions across performance, mass, thermal behavior, radiation tolerance, cost, and schedule.
• Lead preliminary and critical design reviews and maintain power budgets across launch, eclipse, operations, and end-of-life mission phases.
• Model and simulate power generation, battery state of charge, eclipse cycling, transient loads, and power conversion behavior.
• Define validation and qualification campaigns, develop EGSE and HIL environments, and support EMI/EMC, thermal-vacuum, and vibration testing.
• Collaborate with avionics, systems engineering, software, and propulsion teams while mentoring junior and mid-level power engineers.

Requirements

• Bachelor’s degree in Electrical Engineering or a related field.
• At least 8 years of professional experience designing spacecraft or high-reliability electrical power systems.
• Strong experience with solar arrays, Li-ion or LiFePO4 batteries, charge control, DC/DC converters, peak power tracking, and power distribution.
• Experience with radiation effects, radiation-tolerant design, spacecraft power budgeting, and PDR/CDR leadership.
• Proficiency with power modeling and simulation, Altium Designer or equivalent ECAD tools, and SPICE, MATLAB, or similar analysis tools.
• Ability to maintain or obtain TS//SCI clearance and meet U.S. space-technology export requirements.

Nice to have

• Master’s degree in Electrical Engineering, Aerospace Engineering, or a related field.
• Experience with fault management, autonomous protection, EEE parts screening, and qualification.
• Familiarity with EMI/EMC standards, spacecraft charging, power supply stability analysis, and operational orbit regimes such as GEO and LEO.
• Experience with laboratory equipment, EGSE, HIL test environments, or startup engineering environments.

Culture & Benefits

• Company-paid medical, dental, and vision coverage with HSA/HRA options.
• Flexible time off or accrued PTO, paid holidays, parental leave, and sick leave.
• 401(k) retirement plan, fitness reimbursement, and equity participation.
• Daily catered lunch and snacks for in-office employees.
• Values emphasize creative problem-solving, ambitious execution, and collaborative engineering.
