Jobs at PsiQuantum

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.

Design and develop high-performance analog and mixed-signal ICs, leading the entire process from conception through validation and production, ensuring quality and performance in various applications.

The Senior PIC Engineer will design, layout, and verify photonic integrated circuits for quantum computing projects, collaborating across teams to address technical challenges and support foundry tape outs.

The Senior Software Platform Engineer will manage AWS infrastructure, streamline deployment processes, and support GPU clusters for quantum research, ensuring efficient simulations and system security.

Develop and maintain firmware solutions for quantum systems, collaborating with hardware and software teams, and ensuring system performance and reliability.

Lead design, documentation, and integration of electro-optical systems and subsystems, including rack and cryostat layouts, connectivity BOMs, and bring-up procedures. Develop system-level requirements, maintain integration documentation, script controls (Python) to operate lab equipment, coordinate cross-functionally, and design smaller subsystems to validate boxes and subsystems.

Define, validate, and integrate device interfaces for photonic/electro-optic systems. Translate system-level automation and calibration needs into firmware and control-software requirements. Prototype and debug Python control code, partner with firmware engineers for performance migration, and ensure integration, testing, and modelling support for scalable calibration and automation workflows.

The Staff Digital Design Engineer will focus on digital microarchitecture for FPGAs, involving design, verification, testing, and collaboration with cross-functional teams.

Design, simulate, and validate photonic integrated circuits (PDN PICs) and photodetectors. Perform wafer-level and yield data analysis, component and circuit modeling, layout and tape-out, and collaborate on system and packaging validation. Support test, characterization, and development of integrated photodetectors.

Design and deliver optomechanical and optoelectronic OCS packages from prototype to production. Lead DFM/DFx, GD&T, tolerance and risk analyses, fixtures and test setups, BOMs, drawings, and supplier documentation. Coordinate with photonics, process, quality, supply chain, and manufacturing partners to ensure manufacturable, verifiable package designs and production readiness.

The Senior Systems Design Engineer will drive design and development of electro-optic systems, collaborate cross-functionally, and ensure delivery of working box designs.

Lead development, optimization, and scale-up of optical manufacturing processes. Manage a team of engineers to improve yield, throughput, and quality; drive process transfer, validation, SPC/DOE/FMEA activities, CAPA, equipment qualification, and NPI. Coordinate cross-functional work with R&D, quality, supply chain, and vendors to enable high-volume photonics production.

Design and specify quantum optical system functionality, build predictive architectural performance models, evaluate implementation feasibility, and collaborate with photonics, systems, and architecture teams to produce data-driven optical system specifications.

Drive development and optimization of silicon photonic semiconductor processes for Photonic Integrated Circuits. Own yield improvement, defect inspection, failure analysis post-dicing, and process transfers to high-volume manufacturing. Interface with foundries, packaging/assembly teams, and vendors. Use data analysis (e.g., JMP), SPC/DOE, and formal problem-solving (FMEA, 8D) to improve stability, reliability, and yield while managing cross-functional projects.

Develop and optimize software systems for wafer- and die-level photonic IC testing, focusing on high-throughput circuit and functional tests. Define automation specifications, build parallel/asynchronous testing infrastructure, extend vendor platforms, optimize tools, and collaborate with data teams to deliver end-to-end testing solutions.

Run DRC/LVS/ERC/antenna/density and parasitic extraction flows using foundry PDKs; validate electrical routing for photonic integrated circuits; generate extracted netlists and views for post-layout simulation; maintain logs and reports; support block- and chip-level verification and resolve layout issues prior to tapeout.

The Government Programs Specialist is responsible for managing and coordinating high-priority government contracts, ensuring compliance, and leading cross-functional teams. The role involves direct engagement with U.S. government agencies and requires expertise in government program management, contract administration, and communication.

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

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.
