Mechatronic Engineering Internship H/F

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems. The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈‍⬛ . In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously! We're a diverse team of 200+ brilliant minds from over 30 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine.

Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together! Are you looking for an internship where you can apply your mechanical engineering skills to real, cutting-edge systems? As a Mechatronic Engineering Intern, you will work on multidisciplinary projects that combine design, manufacturing, assembly, and integration in a highly technical environment.

This role is ideal for someone with a strong mechanical foundation who is also curious about electronics, instrumentation, and test activities. Join Alice & Bob and contribute to the development of advanced technologies at the frontier of innovation. In this role, you will primarily support mechanical design activities. You will work on new developments and specific high-tech projects involving cryogenic, RF, and electronic applications, with opportunities to assist in validation and testing mechanical and electronic systems.

Through this work, you will help turn complex concepts into robust, practical solutions that support Alice & Bob’s mission to build breakthrough quantum technologies. The internship will start in September 2026.

At Alice & Bob you will:

• Do the mechanical design (3D, 2D) and sizing, including thermal and structural constraints in demanding environments
• Participate in design for manufacturing, including parts technical drawing, material selection, machining constraints, heat and surface treatments
• Follow parts manufacturing, reception, inspection, and assembly
• Assist with the integration of electronic or RF-related components into mechanical assemblies
• Participate in the setup of test benches and experimental configurations
• Support testing, qualification, troubleshooting, and data acquisition on multidisciplinary systems
• Draft assembly procedures, technical documentation, and system/interface diagrams
