Overview

Overview

Provide technical support for the research and development of quantum computers, focusing on developing key hardware components required for quantum computing systems. We are looking at domains such MW and RF technologies, microfabrication and electronics, cryogenic systems, optics and photonics, vacuum technologies and electronics in general. Semiconductor engineers with deep experience in photolithography, interposers/packaging, laser-based fabrication such as selective laser etching and two-photon polymerization are also sought after.

Detail

Prototyping and evaluating new quantum device components

Developing control systems for quantum hardware

Maintaining experimental equipment

Managing clean room infrastructure and devices

Key Activities & Advantages

Integration of multiple technologies, including MEMS, thin-film structures, and ion-trap devices.

Design and operation of cryo-setups relevant to quantum systems.

Access to state-of-the-art fabrication and processing equipment, including:

Selective Laser-Induced Etching (SLE)

Two-Photon Polymerization (2PP)

Ion Beam Sputtering (IBS)

Opportunity to design hardware that directly impacts qubit performance and system scalability.

Company and phase highlights

Opportunity to play a central role in the real-world deployment of ion-trap quantum computers, working at the interface of cutting-edge research and system engineering.

Early-stage growth phase (second year since founding), offering broad responsibility, technical ownership, and meaningful influence over design choices and strategy.

English-speaking, international environment, collaborating closely with world-class researchers and engineers across theory, experiment, hardware, and software.

Strong emphasis on tight feedback loops between theory, experiment, hardware, and control software.
