Optical Design Engineer M/F

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. 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.
Design photonic integrated circuits using our proprietary software.
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.
PhD in Experimental Photonics or Integrated Optics, OR 3+ years of hands-on experimental photonics experience in an industrial setting.
Deep practical experience building and aligning optical setups, including laser systems, optical fiber, and free-space optics.
Comprehensive command of core lab equipment (e.g., autocorrelators, spectrometers, photodiodes, laser diodes, polarization optics, and beam diagnostics).
Experience with femtosecond laser writing or glass-integrated photonics is a plus.
Can commit to full-time lab presence; due to the nature of the role we will not consider remote applicants.
This environment offers unmatched opportunities to learn, build, and grow, but it also requires significant commitment.
granted at this stage, they can become extremely valuable.
An exceptional opportunity for growth.
