Quantum Software Engineer - Qrisp - IQM - IQM Germany (Munich)

At IQM, we build world-leading quantum computers for the well-being of humankind. We design systems to tackle computational challenges beyond the practical limits of classical machines. Our work sits at the edge of science and engineering. It's complex, demanding, and deeply collaborative. We turn deep research into reliable, full-stack systems that drive discoveries in fields like medicine, energy, and technology, reshaping how the world computes. Join the team that gives quantum a heartbeat. You will contribute to Qrisp, one of the most advanced open source quantum programming frameworks, hosted at the Eclipse Foundation and developed across multiple organizations. This includes work across the full stack: from quantum types and algorithm libraries to our JAX based compilation pipeline targeting MLIR for real time quantum classical hybrid programs. Design and implement high level quantum programming abstractions, including quantum types, algorithm primitives, and automatic uncomputation. Develop and optimize the Jasp compilation pipeline: tracing, intermediate representations, MLIR lowering. Implement quantum algorithms (QAOA, VQE, Grover, Shor, QSP, HHL, block encodings) and contribute to the algorithm library. Build and maintain hardware integration layers for IQM and other quantum backends. Write documentation, tutorials, and examples that make the framework accessible to researchers and developers. Engage with the open source community: review contributions, participate in discussions, support users on Discord and GitHub. Contribute to maintaining code quality through testing, CI, and code review practices. Help improve performance through benchmarking and profiling of algorithm implementations. Work effectively in a cross organizational and international team setup.
