Jobs at PsiQuantum

Supports electrical, optical, thermal, and mechanical characterization of photonic devices, packages, and assemblies. Develops test plans, operates laboratory equipment, analyzes data, supports DOE, reliability testing, failure analysis, and root-cause investigations. Creates automated Python-based test and analysis tools, prepares technical reports, maintains laboratory documentation and calibration records, and collaborates with product, packaging, reliability, process, and manufacturing engineering teams.

Leads the design, programming, commissioning, and operation of PLC-based controls for cryogenic infrastructure. Responsibilities include electrical and instrumentation systems, PLC and HMI development, safety interlocks, industrial networks, data acquisition, commissioning, troubleshooting, vendor coordination, and system reliability. The role also provides technical leadership, mentors engineers and technicians, establishes controls standards, and supports global installations and cryogenic operations.

Leads research and development of fault-tolerant quantum algorithms, translating real-world computational challenges into algorithm specifications and implementations. Establishes benchmarks, analyzes asymptotic performance and resource requirements, and collaborates with compilation, applications, architecture, academic, and industry teams. The role includes guiding research programs, validating use cases, evaluating photonic quantum computing implementations, and communicating across technical disciplines.

Coordinates high-volume recruiting activities, including complex interview scheduling, candidate travel and food arrangements, follow-up, applicant record maintenance, correspondence tracking, and recruiting documentation. Ensures accurate data handling and compliance with employment regulations while supporting a positive candidate experience and collaborating with managers across the organization.

Build and expand PsiQuantum’s customer, partner, and ecosystem relationships across hyperscale, AI infrastructure, networking, and telecommunications markets. Lead early co-design engagements, manage technical and commercial RFI/RFP responses, translate customer needs into product requirements, participate in standards and consortium activities, track competitors, and own pipeline forecasting and commercial narratives for business reviews.

Leads technical product management for quantum computing systems, serving as the technical interface with customers, partners, and industry stakeholders. Responsibilities include negotiating product specifications, defining customer-boundary performance tests, translating customer needs into requirements, supporting engineering priorities and trade-offs, authoring technical content, and representing the company at conferences and standards organizations. The role requires deep datacenter networking expertise, switch and fabric architecture experience, optical networking knowledge, product management experience, and exceptional technical writing skills.

Lead the design, development, and deployment of automation software for precision optical alignment systems and nano-positioning hardware. Develop motion-control algorithms, calibration and measurement routines, hardware integrations, testing frameworks, and closed-loop feedback systems. Collaborate across software, optics, mechanical, and systems engineering teams while guiding junior engineers, conducting code reviews, and ensuring reliable, repeatable performance in laboratory and production environments.

Lead development of defense and national security quantum applications: identify use cases, engage government and industry stakeholders, shape proposals and narratives, coordinate with Algorithms/Software teams, own project scope and deliverables, and define go-to-market and partner strategies for fault-tolerant quantum computing.

The Mechanical Design Drafter will develop CAD models, drawings, and documentation for cryogenic systems, ensuring accuracy and manufacturability while participating in system commissioning.

Leads finance business partnership for PsiQuantum’s Australian site development, construction, commissioning, and operational readiness. Oversees capital planning, forecasts, budgets, cash flow, and financial models while serving as finance leader for the Australian legal entity. Manages local statutory reporting, audits, tax compliance, regulatory obligations, transfer pricing coordination, government grant reporting, and governance in partnership with global Finance and external advisors.

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.

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

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.
