Jobs at PsiQuantum

Design and prototype precision photonic hardware: enclosure, packaging, assemblies, and thermal management. Perform mechanical/thermal analysis, validation testing, supplier engagement, and support transfer from lab demonstrator to manufacturable systems.

Design and oversee PCB schematics and layouts for analog and digital circuitry (including high-speed transceivers, 10+ Gbps links, FPGAs, and microcontrollers). Ensure signal integrity and EMI suppression, build and run electro-optic test setups, characterize and debug circuits with lab instruments, develop measurement-driving software, analyze results, and maintain detailed design and test documentation.

Design and own complex optomechanical/optoelectronic subsystem assemblies from prototype to production. Apply DFM/DFA, GD&T, tolerance and FMEA analyses; generate BOMs, process documentation, fixtures, and test setups; perform basic structural and thermal analysis; and maintain revision control (SolidWorks PDM/Arena) while collaborating across cryogenics, optics, electronics, and manufacturing teams to meet schedule and quality targets.

The Senior Optical Process Engineer leads process development for R&D and assembly builds in quantum computing, ensuring quality in systems integration and deployment.

The Photonic Design Automation Engineer will develop and scale the layout-to-netlist flow for silicon photonics, ensuring accurate model extraction and automation for reliable IC tape-outs. Responsibilities include netlist generation, automation pipelines, and collaboration across teams.

The Senior Photonics Engineer will develop ultra-low-loss optical interfaces, combining device concept development, optical simulation, and experimental validation for mode conversion and coupling between optical platforms.

The Director will lead the strategy and operational excellence of compute platforms across cloud and HPC environments, adopting generative AI for productivity. Responsibilities include overseeing system performance, leading team operations, and ensuring reliability in complex infrastructure systems.
