Senior Quantum Architect

Senior Quantum Architect Sygaldry Technologies is seeking an exceptional scientist to serve as a Senior Quantum Architect. In this role, you will own the architectural vision for integrating multiple complementary qubit modalities into a fault-tolerant quantum computing system, bridging error correction theory with the realities of physical hardware. This is a rare opportunity to shape the foundational architecture of a new quantum computing paradigm. What You'll Work On: Define and drive the end-to-end fault-tolerant architecture for novel hardware spanning multiple qubit modalities, from QEC theory down to hardware-level implementation Make and defend high-stakes architectural trade-offs across QEC codes and fault-tolerant logic under real device constraints and noise Translate cutting-edge error correction theory into hardware-aware protocols validated on physical devices Co-design the architecture with target applications in mind, tailoring fault-tolerant resource allocation and logical operations to quantum algorithms for AI and machine learning workloads Establish the simulation, modeling, and benchmarking frameworks used to guide system design and de-risk the technical roadmap Set technical direction and mentor a multidisciplinary team of experimental and theoretical physicists, engineers, and computer scientists You May Be a Good Fit If You Have: A PhD in physics, applied physics, computer science, electrical engineering, or an equivalent degree in a similar field 8+ years of experience in quantum error correction and fault-tolerant architecture, including senior or lead roles A strong publication record in quantum error correction, fault tolerance, or related fields Demonstrated experience implementing and validating QEC or fault-tolerant protocols on real quantum hardware Hands-on experience taking quantum technology from theory through deployment, ideally in an industry setting Strong programming skills in a scientific computing environment A proven track record of leading successful cross-team, multidisciplinary projects Excellent written and verbal communication skills, including the ability to communicate architectural decisions to both technical and executive audiences How We're Different At Sygaldry, curiosity and intellectual courage drive our work. We approach ambitious challenges with a grounded, optimistic, and rigorous culture and know that kind people build the strongest teams. We prioritize mission over ego and collaborate openly with a strong sense of shared purpose. We dream big, yet we execute with a love of detail. We're looking for scientists, engineers, and operators to forge new paths with us at the intersection of quantum and AI.
