Jobs at Xanadu

Lead architecture and development of an internal agentic AI research platform and automation systems. Build scalable, reliable pipelines, SDKs, APIs, and developer-facing tools; enforce engineering standards, mentor engineers, and partner with researchers to translate needs into production-ready developer tools and services.

You will develop high-performance quantum software components, build benchmarking tools, and lead best practices in software development processes.

Develop high-performance software for optimizing quantum hardware. Responsibilities include authoring libraries, enhancing communication protocols, benchmarking, and ensuring software quality.

Develop and maintain JIT and AOT hybrid compilation pipelines for PennyLane, focusing on algorithm implementation, R&D for hardware platforms, and software quality.

You will develop and expand pennylane.ai, collaborate with teams, maintain high code standards, and architect scalable frontend systems.

Lead commercial pipeline for quantum algorithms and applications: identify opportunities, pitch capabilities, convert to funded engagements, manage proposals, pricing, contracts, and oversee delivery while coordinating between research teams and external partners.

The AI Specialist will integrate AI technologies into R&D processes, develop automation tools, collaborate with researchers, and maintain high-quality production code.

As a Software Developer at Xanadu, you will design visualization interfaces, maintain a Python backend, and optimize performance for quantum computing tools while collaborating with diverse teams.

Manage U.S. government-funded research portfolio end-to-end: win funding, coordinate cross-functional proposal development, oversee award execution, ensure milestones and compliance, cultivate government and lab relationships, monitor funding landscape, and represent Xanadu at community events.

Develop and optimize quantum compilation and Quantum Error Correction software to bridge high-level logical abstractions and hardware control. Translate QEC research into production-grade Python and C++ implementations, integrate with compilation IRs and control system APIs, collaborate across hardware and research teams, and maintain high standards for testing, documentation, and CI/CD.

Design, build, and operate integrated nonlinear optical experiments to generate and measure squeezed vacuum. Benchmark and characterize photonic integrated chips using CW and pulsed lasers, implement laser/resonator locking, analyze data with Python, and produce technical documentation to optimize scalable quantum light sources.

Lead IT and financial internal audits and SOX/ICFR compliance activities. Document and test controls, identify and remediate deficiencies, support audit readiness, provide advisory services, and deliver training to stakeholders.

As a Photonics Test Engineer, you will manage high-volume testing setups, develop test plans, train operators, analyze results, and improve workflows.

Hands-on photonics engineer to design, run, and automate phase and polarization experiments, characterize hardware, refine physical and numerical models, and iterate device designs to reduce optical loss and improve system performance while managing thermal and vibration mitigation.

Drive applied AI for R&D by analyzing structured and unstructured data, developing representation, reinforcement, and generative learning methods, implementing ML and optimization algorithms, building reproducible workflows and toolkits, and collaborating with scientists and engineers to improve modeling, simulation, and research efficiency for quantum-computing R&D.

As a Senior Cryogenic Engineer, you will design and develop cryostats, manage hardware lifecycle, and collaborate on detector system improvements. Your role involves testing and optimizing cryogenic systems, as well as deploying large-scale facilities.

As a Staff Data Scientist, lead the development of a decision intelligence product integrating multifaceted R&D data to generate actionable insights using advanced AI and ML techniques.

Develop nonlinear optical components for quantum computing applications, collaborate with teams, and manage design performance using advanced simulation techniques.

The role involves fabricating SNSPDs, enhancing cleanroom capabilities, collaborating on process developments, and ensuring performance metrics are met.

As a Senior Scientist in Optical Metrology, you will drive precision measurement initiatives for superconducting nanowire single photon detectors to enhance performance and scalability.
