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. \nIn 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining-and that now is the time to scale. \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 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 have a clear path to make it real. \nCome join us. \nJob Summary:\nQuantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum we’re building a general-purpose silicon photonic quantum computer to tackle these very problems.\nWe are seeking a senior API & Workflow Platform Architect to design and scale the integration architecture that connects our photonic IC (PIC), passive, and active IC design toolchains. Our engineering workflows span schematic capture, layout, DRC/LVS, EM simulation, optical modeling, process modeling, packaging co-design, and silicon validation. These flows rely on a combination of commercial EDA tools, in-house solvers, Python-based automation, and data pipelines.\nAn ideal candidate is a systems-minded API and workflow architect who thrives at the intersection of SW engineering and advanced hardware design environments (photonics, semiconductor, or EDA toolchains). They bring deep experience designing and governing APIs across heterogeneous systems-proprietary CAD tools, simulation engines, layout databases, EM/optical solvers, test platforms, and CI/CD pipelines-while defining canonical data models that preserve design intent and traceability from schematic through layout, extraction, verification, and tape-out. They are equally comfortable writing production-grade Python services and debating schema versioning strategy, event-driven orchestration, or data lineage requirements. The ideal candidate combines architectural rigor with pragmatism: able to reduce toolchain chaos into scalable, observable, and secure integration platforms that enable automation, reproducibility, and rapid innovation across PIC, passive, and active IC design teams. Above all, they think in systems, communicate clearly across software and device engineering teams, and build platforms that others are excited to adopt.\nResponsibilities:\nKey member of the software solutions team responsible for developing and deploying software for test systems, product platforms and manufacturing data management.\nDesign and standardize APIs enabling interoperability between EDA tools, in-house photonic solvers, PDK infrastructure, and CI/CD systems (Gitlab is a plus).\nBuild and maintain middleware/adapters for commercial and proprietary tools with inconsistent or limited APIs.\nEstablish API versioning, schema validation, and backward compatibility strategies to support evolving toolchains without breaking downstream flows.\nImplement observability and traceability mechanisms (logging, metrics, lineage tracking) to ensure reproducibility and auditability of design runs.\nCollaborate with device, layout, and simulation engineers to translate domain requirements into robust platform abstractions.\nExperience/Qualifications:\nBachelor’s or Master’s degree in Computer Science, Electrical Engineering, Physics, or related technical field.\n7+ years of software engineering experience, with significant exposure to systems integration or platform architecture.\nProven experience designing and governing APIs (REST, gRPC, event-driven architectures) in complex, multi-tool environments.\nFamiliarity with data interchange formats (protocol buffers, avro, etc.)\nExperience integrating with data platforms (DataBricks, Tableau, etc.)\nStrong programming skills in Python (required) and at least one systems or backend language (Go, C++, Java, Rust, or similar).\nExperience integrating heterogeneous tools, including proprietary or vendor software with limited or inconsistent APIs.\nDemonstrated experience defining canonical data models and managing schema/versioning strategy.\nFamiliarity with CI/CD systems, containerization (Docker), and orchestration platforms (e.g., Kubernetes or equivalent).\nExperience implementing logging, monitoring, and observability for distributed systems.\nStrong understanding of software architecture principles: modularity, loose coupling, scalability, reliability.\nExperience working in engineering-heavy domains (EDA, semiconductor, hardware, scientific computing, or similar).\nProven team player with an ability to work effectively across departments, sites, time zones.\nExcellent verbal and written communication skills with an ability to communicate effectively to a variety of audiences.\nStrong critical thinking, creative, innovative, analytical, and detail-oriented problem-solving skills.\nProven track record of impactful results.\nAbility to work independently with limited direction.\nDemonstrated ability to lead and juggle multiple priorities and deliver against a schedule.\nDemonstrated interest in quantum computing.\nAbility to contribute to a fast-paced start-up environment.\nPsiQuantum provides equal employment opportunity for all applicants and employees.
