Photonics engineer
Pubblicato il 17-10-2026 - Ephos in Lombardia
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 $50 M EU CHIPS Act grant—the first ever awarded to a startup.
The role
As a Photonics Engineer at Ephos, you will drive the continuous advancement of our Photonic Integrated Circuit (PIC) capabilities. Taking complete ownership of our femtosecond laser writing process, you will design, prototype, and iterate next-generation architectures.
This role sits at the critical juncture between research and manufacturing and you will play a hands-on role in scaling our technology from R&D; to full-scale chip production while collaborating closely with our manufacturing and product teams.
Your responsibilities
Design photonic integrated circuits using our proprietary software. Fabricate and characterize integrated photonic devices and circuits using in house femtosecond laser writing processes. Translate R&D; breakthroughs into robust, high-yield chip designs engineered for commercial deployment. Design, optimize, and automate custom optical characterization setups and testing protocols. Develop Python libraries to interface and integrate with photonic and electronic instrumentation.
The candidate we are looking for Ph D in Experimental Photonics or Integrated Optics, OR 3+ years of hands-on experimental photonics experience in an industrial setting. Practical experience in PIC characterization: insertion/coupling loss, polarization dependence, mode analysis, active alignment algorithms Deep practical experience assembling, aligning, and troubleshooting comple
