Chemical / Materials Engineer – Space Solar

Location: Los Angeles (Hawthorne), CA

Employment Type: Full-time

Department: Starlight Solar

Travel: Occasional

Support development and optimization of chemistries and processes across cell materials, polymer encapsulation, and barrier systems

Run experiments, characterize materials, and analyze data to inform chemistry and process decisions

Build and maintain lab workflows, sample tracking, and characterization pipelines that support fast iteration

Perform materials and device characterization using techniques such as XRD, XPS, FTIR, DSC, TGA, SEM, photoluminescence, IV, and stability/degradation testing

Partner with senior chemists on root-cause investigations connecting chemistry to device and encapsulation performance

Support scale-up of bench-level chemistry into stable, reproducible processes on the manufacturing line

Contribute to environmental stability strategies — moisture, oxygen, thermal, UV, and radiation tolerance

Maintain lab safety, chemical inventory, and contamination control practices

Push back on unnecessary complexity — simplify chemistries, reduce process steps, and cut overhead wherever it doesn't add value

Bachelor's or Master's degree in chemistry, chemical engineering, materials science, applied physics, or a related discipline

1+ years of hands-on experience with thin-film photovoltaic, optoelectronic, polymer, or related materials (internship and academic research applicable)

Working knowledge of materials characterization techniques and the ability to interpret chemical, thermal, and electrical data

Demonstrated ability to run experiments, collect and analyze data, and draw conclusions from bench work

Master's degree in a relevant discipline

Direct experience with thin-film PV, OLED, OPV, or related solution-processed optoelectronic materials

Hands-on experience with polymer chemistry — encapsulants, adhesives, barrier films, or bonded joints

Experience with solution-processed deposition methods (spin coating, blade coating, slot-die coating) or polymer curing and lamination

Proficiency with common characterization techniques — XRD, XPS, FTIR, DSC, TGA, SEM, AFM, photoluminescence, IV, EQE

Experience translating bench chemistry to larger-area or pilot-scale processes

Familiarity with glovebox operations, cleanroom protocols, and chemical safety

Experience using Python, MATLAB, or comparable tools for data analysis

Exposure to aerospace, space, or other high-reliability hardware environments
