Senior IntegrationAPI architect

PsiQuantumsmission is to build the first useful quantum computersmachines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016 our singular focus has been to build and deploy million-qubit fault-tolerant quantum systems.

Quantum 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.

Our architecture and approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industryincluding partners like GlobalFoundrieswe use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdontfeel heat are immune to electromagnetic interference and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024PsiQuantumannounced 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 definingand that now is the time to scale.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application software and industry teams work directly with leading Fortune 500 companiesincluding Lockheed Martin Mercedes-Benz Boehringer Ingelheim and Mitsubishi Chemicalto prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shiftand a path to mastering challenges that cannot besolvedany other way. The potential is enormous and we have a clearpathto make it real.

Job Summary:

Quantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum were building a general-purpose silicon photonic quantum computer to tackle these very problems.

We are seeking asenior API & Workflow Platform Architectto 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.

An 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 systemsproprietary CAD tools simulation engines layout databases EM/optical solvers test platforms and CI/CD pipelineswhile 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.

Responsibilities:

• Key member of the software solutions team responsible for developing and deploying software for test systems product platforms and manufacturing data management.
• Design and standardize APIs enabling interoperability between EDA tools in-house photonic solvers PDK infrastructure and CI/CD systems (Gitlab is a plus).
• Build and maintain middleware/adapters for commercial and proprietary tools with inconsistent or limited APIs.
• Establish API versioning schema validation and backward compatibility strategies to support evolving toolchains without breaking downstream flows.
• Implement observability and traceability mechanisms (logging metrics lineage tracking) to ensure reproducibility and auditability of design runs.
• Collaborate with device layout and simulation engineers to translate domain requirements into robust platform abstractions.

Experience/Qualifications:

• Bachelors or Masters degree in Computer Science Electrical Engineering Physics or related technical field.
• 7 years of software engineering experience with significant exposure to systems integration or platform architecture.
• Proven experience designing and governing APIs (REST gRPC event-driven architectures) in complex multi-tool environments.
• Familiarity with data interchange formats (protocol buffers avro etc.)
• Experience integrating with data platforms (DataBricks Tableau etc.)
• Strong programming skills in Python (required) and at least one systems or backend language (Go C Java Rust or similar).
• Experience integrating heterogeneous tools including proprietary or vendor software with limited or inconsistent APIs.
• Demonstrated experience defining canonical data models and managing schema/versioning strategy.
• Familiarity with CI/CD systems containerization (Docker) and orchestration platforms (e.g. Kubernetes or equivalent).
• Experience implementing logging monitoring and observability for distributed systems.
• Strong understanding of software architecture principles: modularity loose coupling scalability reliability.
• Experience working in engineering-heavy domains (EDA semiconductor hardware scientific computing or similar).
• Proven team player with an ability to work effectively across departments sites time zones.
• Excellent verbal and written communication skills with an ability to communicate effectively to a variety of audiences.
• Strong critical thinking creative innovative analytical and detail-oriented problem-solving skills.
• Proven track record of impactful results.
• Ability to work independently with limited direction.
• Demonstrated ability to lead and juggle multiple priorities and deliver against a schedule.
• Demonstrated interest in quantum computing.
• Ability to contribute to a fast-paced start-up environment.
