Quantum Software Architect

Quantum Software Architect

Full-time | Germany (flexible locations considered)

A fast-growing quantum technology company is developing scalable quantum computing platforms designed to solve problems beyond the reach of classical machines. Their systems combine cutting-edge hardware with advanced control and software stacks, enabling breakthroughs across science, technology, and industry.

They are now seeking a
Quantum Software Architect
to shape and lead the development of their quantum software infrastructure.

Key Responsibilities

• Define and implement the architecture of the quantum software stack, spanning front-end (programming language/compiler interface) and back-end (hardware-specific compiler) components.
• Lead performance benchmarking and scaling studies for quantum algorithms across different hardware targets.
• Drive hardware/software co-design in collaboration with research, engineering, and architecture teams.
• Establish high standards for maintainable, scalable, and testable code within the software group.
• Monitor and integrate algorithmic and architectural advances into the technology roadmap.
• Contribute to full-stack design decisions, including system scalability and configuration strategies.

Your Profile

• Master's or PhD in Computer Science, Physics, Engineering, or a related technical discipline.
• 3+ years of industry or R&D experience in quantum software, compilers, or architectures.
• Strong knowledge of quantum algorithms, circuit models, and compiler optimization.
• Familiarity with error correction techniques and trade-offs in system architecture.
• Hands-on experience with frameworks such as Qiskit or Cirq.
• Proficiency in Python and at least one lower-level language (e.g. Rust, C++).
• Collaborative, structured working style with excellent communication skills in English.

Desirable Extras

• Prior involvement in designing or implementing quantum compilers in a research or product-driven environment.
• Proven success in hardware/software co-design initiatives.
• Strategic decision-making that has influenced technical roadmaps and implementation approaches.
