RF (Radio Frequency) Test Engineer (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.

We are looking for an RF Test Engineer (m/f/d) for our Siegen location to test, characterize, and validate RF and microwave systems that enable the operation of our next‑generation trapped‑ion quantum computing platforms.

As an RF Test Engineer in the Electronic Engineering Team, you will play a key role in testing, validating, and integrating the RF systems which support our next‑generation quantum computing platforms. In this role, you will be part of an international team of physicists and engineers to develop, characterize, debug, and optimise high‑frequency hardware systems in advanced laboratory environments.

Responsibilities

• Execute and develop validation & characterisation protocols for RF systems.
• Take ownership of RF testing and validation activities, supporting the prototyping, integration, debugging, and validation of RF components and subsystems.
• Contribute technical expertise and validation insights toward the development of next‑generation quantum computing platforms.
• Contribute to improving lab infrastructure, RF testing methodologies, and automation workflows.
• Support the operation team during validation & characterisation of our quantum computing platform with hands‑on expertise of RF systems.

Required Skills

• Bachelor’s or master’s degree in Electrical or Electronic Engineering or a related technical field.
