Head of Manufacturing

About Arinna Arinna is building the energy core of Space 3.0 and frontier tech. We’re pioneering ultra-light, power-dense solar platforms based on next-generation 2D semiconductors, enabling a step-change in how and where solar power can be deployed — from satellites and high-altitude aircraft to lunar and Martian infrastructure. Spun out of Stanford University, Arinna combines breakthroughs in materials science, device physics, and scalable manufacturing to deliver the most power-efficient and lightweight solar technology ever built.

With over $370M in LOIs/off-take agreements and a clear roadmap from pilotto gigawatt-scale production by 2030, we’re on a mission to power the next generation of space and terrestrial systems. We’re backed by leading deep-tech investors and advised by industry pioneers. Our headquarters and pilot facility are in South San Francisco, CA, where we’re scaling our team across R&D, manufacturing, and systems integration.

About the role The Head of Manufacturing will be one of Arinna’s first technical leaders and a key contributor to the design and scale‑up of our coating processes. You will transform lab‑scale ink formulations into uniform, functional thin films that form the foundation of Arinna’s photovoltaic architecture. Your work will center on developing and optimizing slot‑die, blade, and related coating methods for solution‑processed semiconductors and charge‑transport layers.

You’ll collaborate closely with materials and device teams to link film quality to photovoltaic performance and guide the transition from R&D to pilot‑line production. What You’ll Do
• Develop, refine, and scale solution-based coating protocols (slot-die, blade, micro-gravure, etc.) for multilayer PV films.
• Translate ink formulations into high-quality coatings with controlled wetting, drying, thickness, uniformity, and continuity.
• Characterize thin films for their optical (UV/Vis, ellipsometry, etc.), electrical (4-point probe, Hall effect measurement, kelvin probe, IV, etc.) and physical (AFM, SEM, profilometry, etc.) properties to guide process optimization.
• Study the influence of ink chemistry and rheology, substrate surface energy and ink wetting, drying kinetics, and post‑deposition processing on film continuity and performance.
• Collaborate with device and materials teams to link material inputs and deposition parameters to photovoltaic metrics (Jsc, Voc, FF, stability, etc.). Help design and scale experimental setups — including deposition/drying systems (IR/convection drying, air-knife systems, and web handling, etc.) as well as film characterization systems.
• Document process parameters, yield data, and continuous-improvement learnings in a reproducible framework.
• Contribute to safety, workflow, and process documentation as Arinna scales toward pilot‑line production. Qualifications
• M.S. or Ph.D. in Materials Science, Chemical Engineering, Applied Physics, or related field.
• 5+ years of hands‑on experience with solution‑processed thin‑film deposition (slot-die, blade, spin, or similar).
• Proven ability to produce continuous, uniform thin films (
