Spacecraft Solar Array Engineer

Overview Energy is seeking a Spacecraft Solar Array Engineer in Ashburn, VA, to lead the design and optimization of spacecraft solar arrays and power systems. Responsibilities include system architecture, power budget development, and qualification testing. Candidates should have a relevant degree and 5+ years of experience in spacecraft power systems and solar array technologies. Proficiency in CAD and hands-on assembly is required.
Overview Energy is a mission-driven team committed to delivering Space Solar Energy to the world. We operate at the intersection of space infrastructure and energy abundance, providing baseload power across entire continents 24/7, without seasonality or the need for batteries. Headquartered in the Washington, DC area and backed by world-class investors, we are advancing the next generation of clean energy technology.



The Role

Overview Energy's Spacecraft Solar Array Engineer leads the design, development, qualification, and in-orbit performance optimization of spacecraft solar array and power generation systems from concept through end-of-life. The role blends spacecraft power subsystem engineering, structural and thermal design awareness, and hands-on test and integration work to deliver reliable, lightweight, and highly efficient photovoltaic power solutions for orbital and deep-space missions. The ideal candidate has experience with space-rated photovoltaic technologies, deployable solar array mechanisms, and spacecraft power architectures, and can own the solar array subsystem from requirements definition through flight support.



Key Responsibilities

Architect and design spacecraft solar array systems, including cell technology selection, string and panel configuration, array sizing, and interfaces

Perform power budget development, orbital energy balance analyses, and end-of-life power predictions across mission scenarios, eclipse seasons, and pointing constraints

Develop detailed design specifications, interface control documents (ICDs), and technical documentation for solar panels, harnessing, deployment mechanisms, and array drive assemblies using CAD and industry-standard analysis tools

Conduct electrical, mechanical, and thermal analyses of solar array assemblies, including structural margins for launch loads, thermal gradients, degradation, and pointing performance impacts

Support design of deployment and articulation solutions (hinges, hold-down and release mechanisms, solar array drive mechanisms), working with mechanisms and structures engineers to balance stiffness, strength, mass, and deployment reliability

Define, plan, and execute qualification and acceptance test campaigns for solar array assemblies and subcomponents, including electrical, mechanical, environmental, and life testing

Work with manufacturing and supply chain to ensure design-for-manufacturability, process control, and traceability of space-qualified photovoltaic materials and components



Required Qualifications & Experience

Bachelor's degree in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, or related field with a focus on power or space systems

5+ years of experience in spacecraft power systems, spacecraft solar arrays, or closely related photovoltaic hardware for space applications (cell, module, panel, or array-level)

Strong proficiency with CAD and analysis tools for mechanical and/or electromechanical design, plus experience with solar array sizing and performance modeling

Experience with power system design (voltage regulation, string configuration, bypass diodes)

Experience with rapid prototyping and hands-on electrical and mechanical assembly

Experience in soldering techniques relevant to solar module assembly, including hand soldering, reflow methods, and cell interconnection (tabbing/stringing)

Experience with environmental and qualification testing relevant to flight hardware (e.g., vibration, shock, thermal vacuum, radiation), including test planning and data review

U.S. citizenship required



Preferred Skills & Experience

Graduate degree (M.S. or Ph.D.) in Electrical, Aerospace, or Mechanical Engineering with emphasis on spacecraft power systems or space photovoltaics

Hands-on experience with design and qualification of spacecraft solar arrays, solar array drive mechanisms, or power distribution hardware for flight programs

Experience with lightweight, flexible solar array stackups and associated support structures

Familiarity with space qualification and reliability standards (e.g., NASA, ECSS, MIL standards) applicable to power and structural hardware

Experience with radiation effects on solar cells and materials, including shielding strategies and degradation modeling over mission life
