Process Innovation Engineer

Back to Careers Process Innovation Engineer Hardware / Nanofabrication San Francisco Full-time Apply Now Open to both new grads — PhD preferred — and experienced candidates with postdoc and industrial experience. At Piris Labs, we are reimagining compute infrastructure for AI inference. We're hiring Process Innovation Engineers and Scientists to advance our next-generation processing and packaging efforts for broadband comb-based light engines, ultrafast electro-optic conversion engines (>160 GHz), and mixed RF/optics ASIC integration for next-generation ~800 Gbps/lane data rates at extreme efficiency. You will learn across the full stack, own projects, choose how deep to go — and be pushed to go further. You'll work directly with the design team to define the next layer of AI connectivity, help minimize friction between academic research and leading cleanroom practice, and mentor interns to build the pipeline for future openings. RESPONSIBILITIES Develop and optimize nanofabrication processes for advanced photonic and hardware systems Photolithography process development using tools such as MLA150 Heidelberg systems (~1 μm resolution) E-beam lithography tools (100–120 kV class) 2D and 3D metal deposition and lift-off processes Deep UV lithography process development Dry and wet etching processes Sputtering, e-beam evaporation, PECVD, and annealing workflows Process integration for packaging and device fabrication Film and surface characterization: ellipsometry, AFM, SEM Work closely with design and packaging teams to optimize system-level performance REQUIREMENTS Hands-on cleanroom fabrication experience Strong understanding of nanofabrication chemistry and process interactions Experience in UC Berkeley or Stanford cleanrooms is a major plus PhD preferred; MS/BS with strong experience also considered Prior experience in DFB laser fabrication, comb lasers, InP growth, or TFLN processing is a plus Practical, detail-oriented, and excited to build real hardware from first principles Compensation: $100,000–$200,000 depending on experience, plus equity, 401(k), health insurance, and benefits alik@pirislabs.io Apply Now
