Own fabrication process development for our monolithic PIC platform. You will define and qualify cleanroom process flows, drive yield improvement in collaboration with external foundry partners, and build in-house process capability for rapid prototyping. This role sits at the direct interface between device design and manufacturable hardware.

• PhD or MSc in Materials Science, Applied Physics, Electrical Engineering, or related discipline
• Hands-on cleanroom experience with III-V compound semiconductor fabrication (InP preferred)
• Proficiency across core process modules: photolithography, dry/wet etching, dielectric deposition, metallisation, planarisation
• Experience with process characterisation techniques: SEM/TEM, AFM, profilometry, SIMS, electrical test structures
• Familiarity with InP foundry flows and process design kits
• Strong understanding of epitaxial layer design and its influence on device performance
• Statistical process control and yield analysis methodology

• Experience with InP HBT or HEMT process modules
• Background in silicon photonics (SOI, SiN) or heterogeneous III-V/Si integration
• Foundry qualification procedures and process capability indices (Cpk)
• Electro-optic device fabrication: ridge waveguides, EAMs, DFB lasers, SOAs
• Experience transferring processes from R&D to volume foundry environments

• Direct ownership of process development for a novel laser platform with no comparable product on the market
• Competitive salary benchmarked to Zurich deep-tech standards, with meaningful equity participation
• Access to leading cleanroom facilities and collaboration with ETH Zürich research groups
• Small team, high technical ambition — your work determines the product roadmap
• Office in central Zurich — Europe's deep-tech capital
