• Develop and evaluate approaches for large-scale optimization problems
• Apply quantum error mitigation methods and optimized compilation pipelines to bridge ideal algorithms and noisy hardware
• Use hardware-aware algorithm design to maximize performance on planqc's quantum processors
• Work closely with our compilation, hardware and applications teams to integrate your work into the platform

What you bring

• Master's or PhD in physics, computer science, mathematics or a related field, or equivalent practical experience
• Substantial professional software engineering experience with a demonstrated commitment to code quality
• Strong proficiency in a modern programming language commonly used for quantum software, for example Python
• A background in quantum computing with a solid grasp of quantum algorithms and gate-based circuit models
• Familiarity with quantum compilation, circuit optimization or hardware-aware algorithm design
• Comfort working in a collaborative, version-controlled engineering environment
• Professional working proficiency in English (German not required)

Nice to have

• Experience with quantum optimization algorithms in the variational and the fault-tolerant regime
• Experience contributing to larger software collaborations or shared codebases, for example open source, research consortia or multi team industrial projects
• Background in classical optimization or operations research
• Experience with neutral atom platforms
