PsiQuantum is hiring a validation engineer to test the cryogenic electro-optical assemblies behind its silicon-photonics quantum computer. The job is hands-on lab work: defining figures of merit and validation plans, building measurement setups from lasers, detectors, switches, function generators and oscilloscopes, scripting automated measurements into a database, then debugging assemblies and reporting yields back to the design team. Candidates need a physics or engineering degree, five or more years in industry, and cryogenic test experience; single-photon detectors and photonic integrated circuits are preferred.
