Sr. TPV Process Development Engineer

Antora Energy delivers affordable, reliable energy to industry, data centers, and the grid. Our thermal batteries turn low-cost electricity into always-on heat and power, without supply-constrained critical minerals or multi-year construction timelines. We are growing our company with people who put team and mission first, value connection through laughter and joy, and work with humility and openness. We are committed to building a diverse, passionate, and creative team dedicated to a future powered by abundant, clean, low-cost energy. Position Summary Antora is seeking a Process Development Engineer to help drive continued improvements in thermophotovoltaic (TPV) performance. This engineer will own key optical thin-film processes and play a central role in the optical and device modeling that guides Antora's broader efficiency roadmap. The role combines hands-on cleanroom process development with optical design, device modeling, metrology, data analysis, and experimental design. You will use these tools to identify and prioritize the highest-impact opportunities for improving TPV performance, develop and validate solutions in the fab, and translate them into measurable gains in device performance. Roles & Responsibilities Develop and own optical thin-film deposition processes and equipment. This includes coating design, process development, qualification, troubleshooting, process control, and user training. Own the process-side roadmap for improving TPV efficiency. This includes building and using optical and device-level models in Python, with AI-assisted coding and analysis used extensively to accelerate development. Characterize thin films and establish reliable metrology and process controls for properties such as thickness, refractive index, reflectance, uniformity, stress, and adhesion. Compare model predictions with measured device performance, then use the results to improve the models and guide further process development. Plan and run structured process experiments, using tools such as Python, JMP, and AI to analyze results and accelerate process development. Key Qualifications Bachelor’s degree with 5+ years of experience, Master’s degree with 3+ years of experience, or PhD in physics, optics, electrical engineering, materials science, chemical engineering, or a related technical field. Hands-on experience with physical vapor deposition (PVD) techniques such as electron-beam evaporation, thermal evaporation, or sputtering. Demonstrated success developing and qualifying optical thin-film deposition processes. Optical and device-modeling expertise, including designing and optimizing multilayer thin-film stacks and validating model predictions against measured film or device data. Practical knowledge of thin-film characterization and metrology techniques such as reflectometry, FTIR, spectrophotometry, ellipsometry, or related methods. Strong knowledge of semiconductor device physics, particularly…
