The Company:
Solestial is pioneering the future of space-based solar power by developing advanced solar technologies optimized for the harsh conditions of space. Our innovative, low-cost, and scalable solar arrays are engineered for next-generation satellites, spacecraft, and orbital infrastructure. We are driven by a mission to power the space economy and unlock limitless opportunities in orbit and beyond.
The Role:
As a Manufacturing Engineer - Solar Module Manufacturing, you will develop, optimize, and implement the materials and manufacturing processes used to build Solestial's solar modules. You will work closely with Product/ Process Engineering, Manufacturing, Equipment, and Quality teams to translate module designs into reliable, repeatable, and scalable production processes.
Your Mission:
- Develop, optimize, and create manufacturing processes & documentation for solar module assembly and integration.
- Collaborate with design engineering in the evaluation and selection of materials, including polymers, adhesives, thermal interface materials, and electrical insulation materials.
- Translate product and design requirements into practical manufacturing processes, work instructions, and process specifications.
- Plan and execute process trials, experiments, and qualification activities to improve yield, quality, reliability, and manufacturability.
- Coordinate materials characterization, process validation, design verification, and hardware qualification testing.
- Troubleshoot materials, process, and integration issues in partnership with Manufacturing, Product, Equipment, and Quality teams.
- Support the transfer of new module designs and processes from development into production.
- Develop process controls, acceptance criteria, and standard methodologies that ensure consistent, high-quality module production.
- Support supplier selection, material qualification, and ongoing supplier improvement efforts.
- Identify opportunities to improve process capability, cycle time, cost, and scalability as production grows.
- Create and source customer packaging designs.
What You Bring:
- Bachelor's degree in Materials Science, Chemical Engineering, Mechanical Engineering, Manufacturing Engineering, or a related field.
- At least 5 years of experience in process engineering, materials engineering, or manufacturing engineering, preferably within the solar, semiconductor, aerospace, or advanced manufacturing industries.
- Hands-on experience developing, optimizing, and implementing manufacturing processes for complex hardware or assemblies.
- Strong knowledge of materials selection, characterization, and testing, particularly polymers, adhesives, thermal interface materials, and electrical insulation materials.
- Experience translating product requirements into manufacturing processes, material specifications, process specifications, and work instructions.
- Experience with process validation, qualification testing, troubleshooting, root-cause analysis, and continuous improvement.
- Ability to use structured process-development tools such as DOE, SPC, process capability analysis, and PFMEA.
- Experience supporting the transfer of new products or processes from development into manufacturing.
- Familiarity with supplier selection, material qualification, supplier development, and ongoing performance evaluation.
- Strong cross-functional communication skills and the ability to work effectively with Product, Manufacturing, Equipment, and Quality teams.
What Gives You an Edge:
- Experience with solar cell or solar module manufacturing, assembly, and integration.
- Background in semiconductor, photovoltaic, aerospace, or other high-reliability manufacturing environments.
- Hands-on experience with module integration processes such as bonding, lamination, encapsulation, interconnection, thermal management, or insulation.
- Experience scaling new materials and processes from development through qualification and production.
- Familiarity with spaceflight hardware requirements, environmental testing, and qualification standards.
- A practical, hands-on approach to troubleshooting and a willingness to work directly with equipment, materials, and production teams.
- Comfort operating in a fast-paced environment where processes are still being developed and priorities evolve.
