Semiconductor Process Engineer

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‑optical device fabrication: ridge wave guides, 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
