Quantum Error Correction Scientist

Company Description

At Qarakal Quantum, we’re not just building quantum computers — we’re reimagining what computing can be from the ground up. Based on superconducting qubits, we are creating modular and scalable quantum systems engineered for real-world impact. We believe true innovation happens when the entire stack is designed together. That’s why our co-design philosophy unites hardware, algorithms, and applications into one integrated effort that drives breakthroughs beyond incremental progress. If you’re ready to push the boundaries of physics, math, and engineering, and help invent the architectures of tomorrow’s quantum future, this is the place for you! 

Role Description

We are looking for a passionate Quantum Error Correction (QEC) Scientist to join our Algorithms & Applications Team. In this role, you will design, implement, and optimize quantum error correction strategies that directly shape the performance of our superconducting qubit processors. Working at the intersection of design, theory, and experiment, you will collaborate across hardware, software, and applications to drive true hardware-aware co-design.

What you'll do: 

• Evaluate and implement state-of-the-art quantum error correction codes tailored to superconducting quantum processors. 
• Translate hardware constraints to algorithmic requirements and guide hardware design with QEC needs. 
• Develop and benchmark decoders under realistic noise models and guide improvements in calibration and control. 
• Collaborate with hardware teams to integrate QEC into the control stack and system architecture. 
• Publish findings in academic journals and present at key conferences. 
• Stay current with developments in quantum information science and identify opportunities to integrate them into our stack. 

Position Requirements: 

• PhD in Quantum Information, Physics, Computer Science, Mathematics, or related field (or MSc with 2+ years of relevant experience). 
• Demonstrated expertise in QEC (e.g. surface/color codes, qLDPC, stabilizer formalism, decoding algorithms). 
• Proficiency in Python, C++, or equivalent OOP language.  
• Excellent communication and collaboration skills in interdisciplinary teams (English or Hebrew). 

Preferred: 

• Experience with quantum hardware, especially superconducting qubits (hardware‑level programming a plus). 
• Familiarity with lattice surgery, magic state injection, and related advanced QEC schemes. 
• Track record of publications or open-source contributions in quantum computing.
