Jobs at PsiQuantum

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 Integrated Photonics Engineer will design, test, and optimize active photonic devices while collaborating with cross-functional teams and mentoring juniors.

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 Cryogenic Engineer will lead the installation and operation of helium cryoplants, optimize systems, troubleshoot issues, and provide technical leadership.

The Photonic Circuits Designer will collaborate with technical teams to design photonic integrated circuits, develop software tools, and perform circuit analysis.

The Principal Power Systems Architect will design and manage large-scale power systems for quantum computing, ensuring power integrity and compliance with stringent requirements.

The role focuses on enhancing testing capabilities for quantum systems through new tooling, process improvements, and collaboration with engineers on testing methodologies.

Lead installation and operation of cryogenic and ultra-high vacuum systems for quantum computing, ensuring optimal performance and reliability.

The Test Automation Engineer will develop and implement software, methods, and test infrastructure for electro-optical subsystems, lead high-speed test station projects, and automate data collection and analysis.

The Integrated Photonics Engineer will design and execute experiments to test and characterize photonic circuits, develop automated workflows, and collaborate with design teams to enhance device performance.

The Quantum Electronics Engineer will design electronic systems for quantum hardware, focusing on RF design, electro-optic modulation, and working with high-speed electronics while collaborating closely with photonics teams. Responsibilities include implementing low-latency control systems and optimizing complex quantum hardware systems.

Serve as liaison between Electronics and System Engineering to troubleshoot PCBA issues, perform failure analysis on returns and yield loss, implement corrective actions in design and test, improve PCBA test coverage, and provide training while collaborating with thermal, mechanical, firmware, RTL and optical teams.

The Principal System Integration Lead will translate quantum system requirements into scalable hardware architecture, driving integration from concept through deployment while managing cross-functional teams and ensuring alignment between hardware and system design.

The Senior Optical Fibre Engineer will develop and evaluate advanced optical fibre for high-performance optical systems, using simulation tools and conducting experiments to validate fibre properties and performance.

Lead the design of integrated photonic systems, driving development from architecture to validation. Collaborate with teams on high-performance optical platforms, focusing on scalable, low-loss circuits and switching elements.

The Silicon Photonics Engineer will design and implement photonic integrated circuits, support tapeouts, resolve technical issues, and develop documentation for silicon photonic devices.

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.
