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.

• 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.
• 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.

• Experience with solar cell or solar module manufacturing, assembly, and integration.
• Background in semiconductor, photovoltaic, aerospace, or other high-reliability manufacturing environments.
