About The Position

PsiQuantum’s Principal Hardware Engineer will support the Electronics team developing photonic switching products. The role collaborates with thermal, mechanical, firmware, and optical engineers to deliver hardware designs that meet overall system architecture and product requirements. The engineer will architect PCB designs, develop and review circuitry and layouts, validate and debug analog, digital, and electro-optic systems, and document designs and test results. The role also involves signal-integrity simulation and developing bench software to support measurements.

Requirements

Master’s or Ph.D. degree or above in Electrical Engineering, Physics, or an equivalent field.
10 years of relevant experience in product development and release to volume manufacturing, leading to multiple successful commercial products.

Responsibilities

Architect PCB hardware designs from functional requirements documents.
Design schematics and oversee PCB layout for analog and digital circuitry, including DACs, ADCs, high-speed transceivers, FPGAs, microcontrollers, clock distribution, power-supply filters, inrush-current limiters, and power distribution.
Ensure robust signal integrity and EMI suppression in designs.
Design and create test setups for electro-optic modules.
Characterize, optimize, and debug analog, digital, and electro-optic circuitry using mixed-signal and sampling oscilloscopes, vector network analyzers, signal generators, multimeters, and DC power supplies.
Develop bench software to drive measurements.
Analyze data and extract key performance parameters.
Maintain detailed documentation of hardware designs, test results, and design changes.
Perform signal-integrity simulations using Cadence and Ansys tools.
