We are a spin-off of the Max Planck Institute of Quantum Optics, based in Garching near Munich. Our software team owns the stack that turns a quantum program into the laser pulses and atom movements our machines execute. As a Senior / Lead Quantum Compiler & ISA Engineer, you will lead how programs reach our neutral-atom hardware: the compiler architecture, its intermediate representations, and the instruction set at every level from gates to pulses and atom movement. Depending on experience, the role can **grow into technical lead for compilation**. You work between physicists, software developers, control-system engineers, and our algorithm and quantum error correction (QEC) teams. You own the interfaces between them: which operations the hardware exposes, how programs are lowered onto them, and how people can see what the compiler did. #### Your responsibilities **Compiler infrastructure** - You work on the architecture of a **multi-level compiler**, with dialects from logical circuits through native gates, atom layouts down to the shuttling level. - Design analysis and optimization passes driven by hardware cost models such as fidelity, timing and atom-loss budgets. - Keep the stack interoperable with standards such as OpenQASM 3 and QIR. **Instruction set architecture (ISA)** - Define the instruction set at each abstraction level, from the gate set users target down to timed pulse and movement instructions. - Own the interface to the control system: what the compiler hands over, which timing guarantees hold, and which constraints it must respect. - Decide with physicists and control engineers which operations each level exposes, and how the ISA is versioned as software and hardware evolves. **Tooling** - Build tools that make compilation visible: IR dumps between passes, pass diffing, visualizations of atom positions and schedules, and replay of failed jobs. - Add verifiers, property-based tests and equivalence checks so that every pass can be trusted. - Build tools for our algorithm and QEC teams, such as resource estimation to provide fast feedback on how a circuit maps to the machine and be involved in shaping the next generation of compilers for our error corrected quantum computers. **Technical leadership** - Make and document architecture decisions for the compiler and ISA. - Review designs and code across the team. - Represent compilation in hardware co-design discussions and, where it fits, in open-source and standards communities. #### What you bring - A PhD or MSc in computer science, physics or a related field, or equivalent industry experience. - **3+ years building compilers**, IR-based tools or language toolchains, in industry or research. - **Deep hands-on experience with MLIR or xDSL**, or with LLVM or a comparable SSA-based infrastructure. - A track record of setting the architecture of a compiler or toolchain and taking it to production. - Deep Knowledge and Understanding of **Python** - Comfort reasoning about hardware: instruction sets, timing, scheduling, and resource constraints. - Interest in quantum computing and in working closely with physicists. Prior quantum experience is not required. #### Nice to have - Other programming languages like C++ or Rust. - Quantum compilation tools such as Qiskit, Qrisp, tket, Cirq, CUDA-Q, Catalyst or Kirin/Bloqade. - Quantum error correction, stabilizer simulation (e.g. Stim), or logical-level compilation. - Experience around GPUs and Optimization. - Open-source contributions or private projects. #### Why join planqc - **Real ownership**: you shape the compiler and ISA of machines being built now, with room to grow into a lead role. - Daily contact with the lab: your passes run on real neutral-atom hardware. - A interdisciplinary team of physicists, engineers and computer scientists. - Competitive salary. **Benefits at planqc** - Flexible working: Flexible hours and hybrid work where the role allows. - Company pension: Betriebliche Altersvorsorge with an employer contribution. - Health and fitness: EGYM Wellpass for gyms, pools and studios, plus regular Health Days. - Job bike: Lease a bike through planqc. - Learning and development: Trainings and conference participation, including international conferences. Plus regular internal learning sessions where colleagues share their knowledge. - Relocation and visa support: Practical support for international hires and their move to Germany or Austria. - Four locations: Headquarters in Garching, an office in central Munich, plus sites in Ulm and Innsbruck. - Team culture: Regular team and company events throughout the year, from after work socials to our summer and Christmas parties. ## How to apply Apply on the job page, https://germanydevjobs.com/jobs/planqc-quantum-compiler-engineer-0315tc2: its Apply button opens the employer's own application page. ## More jobs from planqc - [Quantum Systems Architect](https://germanydevjobs.com/jobs/planqc-quantum-systems-architect-9aaq288): planqc, Munich, Germany.
