Position

Quantum Error Correction Engineer (Munich, Germany)

Responsibilities

• Develop and analyze quantum error‑correcting codes with realistic connectivity and hardware constraints.
• Design and evaluate fault‑tolerant operations, including multi‑qubit logical gate strategies such as lattice surgery.
• Contribute to fault‑tolerant quantum algorithms and algorithm‑specific error correction approaches.
• Design, benchmark, and improve decoding algorithms, including graph‑based decoders (belief propagation, union‑find, minimum‑weight perfect matching) and machine‑learning‑based decoding approaches.
• Implement and optimize decoding algorithms in Python, C/C++, or Rust, with potential deployment on FPGA platforms.
• Perform resource estimation and scalability analysis for error‑corrected architectures.
• Collaborate closely with hardware, control, and software teams to ensure alignment between error‑correction strategies and real QPU capabilities.
• Publish and present high‑impact research results in leading scientific journals and conferences.
• Maintain high internal and external code quality standards, ensuring scalability and long‑term maintainability.

Qualifications

• Ph.D. in theoretical physics, computer science, applied mathematics, or a similar field.
• Deep knowledge of quantum error‑correcting codes, fault‑tolerant quantum algorithms, or decoding algorithms.
• At least 2 years of professional experience developing scientific software in Python, C/C++, or Rust.
• A strong publication record, including at least two scientific papers in high‑impact journals.
• Ability to clearly communicate complex technical concepts across interdisciplinary teams.
• A collaborative mindset and comfort working in a team‑oriented research and engineering environment.
• At least 3 years of experience in one or more of the following:
  • Designing quantum error‑correcting codes under connectivity constraints.
  • Multi‑qubit logical gate implementations (e.g., lattice surgery).
  • Fault‑tolerant quantum algorithms.
  • Algorithm‑specific error correction (e.g., fermionic simulations).
  • Decoding algorithms (belief propagation, union‑find, MWPM).
  • Machine‑learning‑based decoding methods.
  • FPGA‑based implementation of decoding algorithms.

Preferred skills

• Knowledge of the theory of superconducting qubits.
• Experience working closely with hardware or experimental quantum teams.
• A drive to keep your expertise current and continuously expand your knowledge.
• The ability to create elegant, structured solutions in complex theoretical and technical landscapes.
• Strong ownership of code quality, testing, and documentation.
• An understanding of how to balance immediate project goals with long‑term scalability and extensibility.

Benefits

• An opportunity to work with a passionate and diverse team on an important mission.
• A unique opportunity to make a real impact on the future of quantum.
• A competitive salary, complementary health insurance, local transportation, lunch benefit, sports benefit, corporate benefit, and more.
