Staff Optical Fiber Link Design Engineer (Optical Distribution Network) at PsiQuantum, Milpitas
Job Description
PsiQuantum’s System Design organisation is hiring a staff optical fiber link design engineer in Milpitas. The role designs the optical distribution network that connects the photonic chips, subsystems and control systems of PsiQuantum’s quantum computers: fiber routing, splice plans, optical I/O and link budgets that keep loss within the architecture’s limits. It also sets rules for splicing, connectors, cleanliness and handling, and qualifies advanced fiber components from vendors.
