Glass Panel Manufacturing
About Ephos
Ephos is building vertically integrated, advanced packaging solutions on glass panels. We transform raw glass into electronic and optically active substrates for die-to-die connectivity, manufactured entirely within our own facilities. Our systems are built for companies developing AI accelerators, including hyperscalers and top-tier chip designers.
We have already delivered products to leading global firms, and we are currently building a new fabrication facility to scale production by 100x. This expansion is backed by a $50M EU CHIPS Act grant—the first ever awarded to a startup.
The role
We are seeking a Process Engineer specializing in glass panel manufacturing to join our Process team. In this role, your primary focus will be owning, optimizing, and scaling our glass processing covering a few different tools and technologies. You will bridge the gap between R&D; and mass production, ensuring our glass panels meet strict optical, structural, and cosmetic standards while maximizing yield and throughput.
Your responsibilities
Lead the development, qualification, and continuous improvement on the newly purchased tools at our FAB-2 facility.
Contribute to prototypes production in FAB-2 or other external facilities using lithography, metal deposition, encapsulation and other microfabrication techniques.
Monitor process performance using Statistical Process Control (SPC). Identify root causes of defects (e.g., uneven etching, micro-cracks, contamination) and implement robust corrective actions.
Partner with equipment and chemical vendors to optimize parameters to develop the best possible performance.
Characterize new glass materials and process parameters through rigorous DoE to improve process windows and reduce cycle times.
Maintain strict adherence to environmental and safety protocols, particularly regarding the handling, recycling, and disposal of hazardous etching chemicals (e.g., HF, specialized acids, o
