Jobs at PsiQuantum

Lead installation, commissioning, and maintenance of large-scale cryostats and associated vacuum, instrumentation, and control systems. Develop commissioning procedures, perform diagnostics, preventative and corrective maintenance, and collaborate with cross-functional teams to ensure system reliability, safety compliance, and documentation in an R&D/production environment.

The intern will develop quantum algorithms, optimize subroutines, compile algorithms, apply architecture-aware optimizations, and estimate quantum resources.

Design and run experiments to characterize integrated photonic circuits, test devices (couplers, interferometers, EO modulators), develop automated control and data acquisition with Python, analyze results, collaborate with designers to troubleshoot and scale testing for large photonic systems, and document findings.

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 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.

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.

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 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.

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.

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.

Leads finance strategy for the Optical Circuit Switch business unit, partnering with the General Manager and leadership team on planning, forecasting, performance management, product economics, pricing, commercial evaluations, investment decisions, and growth initiatives. The role develops financial models, evaluates product profitability, supports make-versus-buy and partnership analyses, and provides decision support for technology investments and market expansion.

Design and implement algorithms and software for scalable databases in quantum computing systems. Collaborate on various technical teams and ensure performance and reliability of software.

Design, support, and maintain CAD tools and databases for VLSI design, develop automation scripts, and troubleshoot issues in a quantum computing environment.
