Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems. \nQuantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries. \nOur architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry, including partners like GlobalFoundries, we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don't feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure. \nThat approach has since been tested at the highest level of scrutiny the U.S. government applies to emerging technology, and it has held up. In 2025, PsiQuantum closed a $1 billion funding round that valued the company at $7 billion. In 2026, the U.S. Department of Commerce signed a $100 million Letter of Intent under the CHIPS and Science Act, followed by a $125 million agreement with DARPA under Stage C of its Quantum Benchmarking Initiative, PsiQuantum's most valuable U.S. government agreement to date. This year, we also broke ground on our utility-scale quantum computer in Brisbane, Australia, and continued building out our Chicago site. Victor Peng, our CEO, and co-founder Jeremy O'Brien, now Executive Chairman, lead a team and board that reflects how seriously the world is taking this build, joined this year by Intel's Lip-Bu Tan and Atomico's Niklas Zennström. \nPsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies, including Airbus, Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical, to prepare quantum solutions for real-world impact. \nQuantum computing is not an extension of classical computing. It represents a fundamental shift, and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we now have the funding, the government validation, and the sites under construction to make it real. \nJob Summary:\nWe are seeking a senior- or staff-level engineer to own the detailed design, integration, and qualification of electro-optic hardware modules used in advanced photonic systems. Working alongside the Photonic Hardware Architect, this role turns system requirements and high-level concepts into robust rack-mountable or blade-format products containing optical amplifiers, attenuators, polarization controllers, power monitors, control electronics, and related optical and electro-optic subassemblies. The engineer will lead internal design execution, direct external development partners, and establish the experimental evidence and verification rigor needed for sound technical and production decisions.\nOverview:\nOwn detailed electro-optic module design from requirements and concept selection through prototype build, EVT, DVT, and transfer to manufacturing.\nTranslate system architecture into complete optical, electrical, mechanical, thermal, firmware-control, and test interfaces for rack-mountable boxes and blade assemblies.\nServe as the hands-on technical lead connecting system architects, photonics, electronics, mechanical engineering, test, operations, and external suppliers.\nResponsibilities:\nOwn the detailed design and integration of electro-optic modules incorporating optical amplifiers, variable or fixed attenuators, polarization controllers, optical switches, splitters, couplers, filters, power monitors, photodiodes, control electronics, and associated fiber infrastructure.\nConvert system and subsystem requirements into engineering specifications, interface definitions, optical power and noise budgets, schematics, component selections, bills of materials, mechanical layouts, tolerance analyses, and assembly documentation.\nLead design trade studies across optical performance, noise, stability, dynamic range, control bandwidth, thermal behavior, reliability, serviceability, manufacturability, cost, and schedule; document decisions and residual risks.\nDesign controlled experiments, select appropriate instrumentation and statistical methods, analyze data, and make technically defensible decisions when models, component data, or vendor claims are insufficient.\nPlan and execute module bring-up, characterization, margin testing, environmental testing, fault-injection testing, and reliability-oriented testing; automate measurements and data reduction where practical.\nAuthor verification and acceptance requirements, test plans, procedures, and reports for engineering builds and externally supplied modules, including clear pass/fail criteria and traceability to requirements.\nLead EVT and DVT for internally developed and vendor-developed hardware; investigate failures, drive root-cause analysis and corrective actions, and ensure closure of test anomalies and design risks.\nOversee internal design reviews and configuration control, ensuring that drawings, schematics, BOMs, firmware or control interfaces, calibration data, and released test documentation remain consistent and production-ready.\nOwn technical collaboration with contract manufacturers and specialist vendors, including statements of work, requirements flow-down, design reviews, prototype acceptance, supplier qualification, and resolution of quality or yield issues.\nPartner with manufacturing and operations to implement design-for-manufacture, design-for-test, calibration, alignment, service, and end-of-line acceptance strategies that support repeatable builds and field use.\nCommunicate status, decisions, risks, and recovery plans clearly across functions; provide concise, decision-oriented executive updates without losing the underlying technical rigor.\nCore competencies / what success looks like:\nDetailed module designs meet performance, interface, safety, reliability, manufacturability, and serviceability requirements with objective verification evidence.\nEVT and DVT are executed with complete, traceable documentation; failures and technical risks are surfaced early and closed decisively.\nInternal teams and external suppliers deliver build-ready designs, consistent documentation, and repeatable acceptance results.\nTechnical decisions are made quickly but rigorously through focused experiments, clear trade studies, and concise communication.\nExperience/Qualifications:\nRequired Qualifications\nB.S. or higher in electrical engineering, optical engineering, physics, mechanical engineering, or a related field, with substantial relevant industry experience.\nDemonstrated ownership of detailed electro-optic or opto-mechanical hardware design through prototype, verification, qualification, and manufacturing release.\nStrong hands-on knowledge of fiber-optic components and subsystems, including amplifiers, attenuators, polarization control, optical power monitoring, photodetection, and practical fiber management.\nExperience integrating optical, analog and digital electronics, thermal management, mechanical packaging, connectors, power distribution, communications, and safety features in rack-mountable or blade-format equipment.\nProficiency developing requirements, interface-control documentation, optical and electrical budgets, verification matrices, test plans, procedures, acceptance criteria, and formal test reports.\nStrong experimental judgment, including test design, instrumentation, measurement uncertainty, data analysis, and the ability to distinguish component limitations from integration or test artifacts.\nExperience leading EVT/DVT, hardware bring-up, structured debugging, failure analysis, root-cause investigation, and corrective-action closure.\nProven ability to direct vendors and contract manufacturers while maintaining technical ownership, schedule discipline, document quality, and configuration control.\nExcellent written and verbal communication, with the ability to collaborate across disciplines and distill complex technical work into efficient executive-level updates.\nPreferred qualifications:\nExperience with high-power or low-noise optical amplification, photonic calibration, metrology, quantum photonics, or precision instrumentation.\nFamiliarity with laser and electrical safety, EMI/EMC, thermal and environmental qualification, reliability methods, and applicable product-compliance practices.\nExperience creating automated laboratory or production test systems using Python, LabVIEW, MATLAB, or similar tools.\nWorking knowledge of statistical tolerance analysis, measurement-system analysis, design of experiments, reliability growth, and supplier quality methods.\nExperience transferring low-volume, high-complexity hardware into repeatable production and supporting sustaining engineering or field failure analysis.\nPsiQuantum provides equal employment opportunity for all applicants and employees.
