Process Engineer - Solar Cell Module Manufacturing & Integration

About the role

The Process Engineer - Solar Cell Module Manufacturing & Integration will be responsible for developing, optimizing, and implementing the manufacturing processes used to build Solestial’s solar modules. This role involves close collaboration with Product, Manufacturing, Equipment, and Quality teams to translate module designs into reliable, repeatable, and scalable production processes.

Responsibilities

• Develop, optimize, and implement manufacturing processes for solar cell 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
• 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

Requirements

• 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
• Experience using structured process-development tools such as DOE, SPC, process capability analysis, and PFMEA
• 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

Qualifications

• 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
