Quantum Processing Unit Architect QPU Architect (f/m/d)

eleQtron develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.

Your Responsibilities:

As a QPU Architect, you will take the lead on compiler architecture, software optimisation, and HW/SW co‑design. You will define the structure of our quantum software stack across both front‑end and back‑end compilers, ensure it scales with our architecture, and contribute to the broader technology roadmap. This is a key position for someone who has done this before and wants to help shape what quantum computing looks like in practice.

• Drive hardware‑software co‑design approach to optimize quantum computer architecture for use cases and vice versa
• Performance analysis and optimization of quantum algorithms across architectures
• Define and choose compute benchmarks to steer development of our quantum computer architecture
• Support in maintaining of technology roadmap and drive related requirements engineering
• Design and specify compiler front‑end (quantum language), back‑end (machine‑specific) and optimization strategies together with our quantum software applications team
• Ensure clean, testable and scalable implementations together with our quantum software team

Required Skills:

• Master’s degree in computer science, physics or engineering
• 3+ years in industry or post‑graduated R&D experience on quantum computing related topics
• 3+ years of experience in Python, Rust, C++ or similar programming languages
• Demonstrable working knowledge of quantum programming with frameworks such as Qiskit and Cirq
• Deep understanding of quantum computing paradigms and architectures, including various hardware realizations
• Profound expertise in quantum algorithms and compilers
• Strong grasp of quantum circuit design
• Knowledge of quantum error correction methods
• Excellent English skills, both written and spoken

We value:

• Experience designing or implementing quantum compilers in a product‑oriented environment
• Experience driving cross‑functional co‑design efforts between hardware and software teams
• Initiating roadmap‑impacting decisions with real implementation consequences
