Job summary

Ephos is seeking a Process Engineer specializing in glass panel manufacturing to own, optimize, and scale our glass processing while ensuring optical, structural, and cosmetic standards and maximizing yield.

You will bridge R&D and mass production, lead tooling validation at FAB-2, and collaborate with vendors to achieve top performance and throughput. This is a full-time on-site role in our Lombardy facility.

Qualifications

• Bachelor’s or Master’s degree in Physics, Chemical Engineering, Materials Science, Chemistry, Mechanical Engineering, or a related technical field.
• 3+ years of hands-on process engineering experience in glass panel manufacturing, display technology, solar/photovoltaic modules, or semiconductor processing.
• Experience in new tool validation is a plus.
• Proficiency in SPC and data analysis software is a plus.
• Strong understanding of DoE and FMEA methodologies.
• Familiarity with metrology tools used to measure glass thickness, surface roughness, and etch depth (e.g., profilometers, ellipsometers, microscopes).

Responsibilities

• Lead the development, qualification, and continuous improvement on newly purchased tools at FAB-2.
• Contribute to prototypes production in FAB-2 or other external facilities using lithography, metal deposition, encapsulation and other microfabrication techniques.
• Monitor process performance using SPC. Identify root causes of defects 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 DoE to improve process windows and reduce cycle times.
• Maintain strict adherence to environmental and safety protocols, including handling and disposal of hazardous etching chemicals.

Job description

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, or gases).

The candidate we are looking for

• Bachelor’s or Master’s degree in Physics, Chemical Engineering, Materials Science, Chemistry, Mechanical Engineering, or a related technical field.
• 3+ years of hands-on process engineering experience in glass panel manufacturing, display technology (LCD/OLED), solar/photovoltaic modules, or semiconductor processing.
• Experience in new tool validation is a plus.
• Proficiency in SPC (Statistical Process Control), data analysis software is a plus.
• Strong understanding of DoE (Design of Experiments) and FMEA (Failure Mode and Effects Analysis) methodologies.
• Familiarity with metrology tools used to measure glass thickness, surface roughness, and etch depth (e.g., profilometers, ellipsometers, microscopes).
• Can commit to full time lab presence; due to the nature of the role we will not consider remote applicants.
• Ephos is a demanding environment. We operate with exceptional ambition and move fast, because the market gives us no other option. We expect excellence from you, as we do from one another. This environment offers unmatched opportunities to learn, build, and grow, but it also requires significant commitment.

What we offer

• Top of the market salary.
• Stock options; granted at this stage, they can become extremely valuable.
• An exceptional opportunity for growth.

The hiring process

• Interview with our Head of Process.
• Interview with a senior Process Engineer of our team, with a practical exercise.
• Interview with our CEO.
