Quantum Error Correction Theorist

About Sygaldry

Sygaldry Technologies is building quantum-accelerated AI servers to exponentially speed up training and inference. Our AI servers will address the problem of rising compute and energy costs for scaling AI, enabling companies to innovate faster and more affordably. Sygaldry AI servers combine multiple qubit types within a single, fault-tolerant architecture, leveraging their respective strengths while avoiding their limitations. We're building the infrastructure for quantum superintelligence. We pioneer new domains in physics, engineering, and AI, tackling the hardest challenges with a grounded, optimistic, and rigorous culture. Our team is growing—we're looking for scientists who want to shape how quantum and AI intersect, and unlock the potential of both together.

About You:

Sygaldry Technologies is seeking an experienced scientist to serve as a Senior Quantum Error Correction Theorist. In this role, you will be responsible for developing quantum error correction schemes to integrate multiple complementary qubit modalities into a fault-tolerant architecture. This is a rare opportunity to join an early team and help lay the foundation for a new quantum computing paradigm.

About the Role

What You'll Work On:

• Design and evaluate quantum error correction schemes for novel hardware architectures with multiple qubit modalities

• Develop efficient protocols for fault-tolerance under hardware-specific constraints and noise models

• Build simulation and modeling tools for system design and analysis

• Lead high-impact research projects with 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

• 5-10 years of experience in quantum error correction

• Publications in quantum error correction or related fields

• Possess a strong programming skills in a scientific computing environment

• Proven track record of successful cross-team collaborative projects

• Excellent written and verbal communication skills

Strong Candidates May Have:

• Experience translating cutting-edge R&D into commercial products or roadmap milestones

• Experience deploying quantum error correction schemes on real quantum devices

• Experience translating abstract models of error correction into hardware-aware protocols

• Experience with decoding

Why This Matters

Generative AI is bottlenecked by compute. Training and inference costs for diffusion models are measured in GPU-years and megawatt-hours. If quantum acceleration can fundamentally change these economics, it changes what generative AI can do—and who can access it. Your work could help make these models more efficient, more capable, and more sustainable.

How We’re Different

We believe kind people build strong teams: we prioritize mission over ego and share our thinking transparently. We celebrate curiosity, dream big, and forge our own path, but always with strong execution towards measurable goals. Our teams collaborate closely together, questioning assumptions, and balance optimism with rigorous validation. We move fast and build things, knowing that perfect is the enemy of done.
