Job description

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 Application Engineer (m/f/d) to test, validate, and optimize RF subsystems at the core of our trapped-ion quantum computing platform in Siegen.

Responsibilities

As a RF application engineer in the Electronic Engineering Team, you will play a key role in testing, characterizing, validating, and integrating RF systems that support our next-generation quantum computing platforms. In this role, you will work closely with our international team of physicists and engineers to develop, characterize, debug, and optimize high-frequency electronic hardware systems in advanced laboratory environments.

• Setting up, integrate, configure, and validate low-noise DC and RF electronic hardware components and subsystems within our quantum computing platforms.
• Support system operation, bring-up, commissioning, and troubleshooting of electronic subassemblies, control systems, and laboratory equipment.
• Collaborate closely with engineering and firmware teams to develop and integrate RF subsystems for next-generation quantum technologies.
• Take ownership of developing new validation protocols and defining characterization standards.

Requirements

Required Skills:

• Bachelor's or master's degree in Electrical Engineering, Electronics, RF/Microwave Engineering, Physics, or a related field
• 3-5 years of professional experience in electronics engineering, application engineering, hardware integration, or a comparable technical role.
• Hands-on experience with high-speed digital and RF hardware systems.
• Strong understanding of RF systems, including RF measurements, debugging, and hardware validation.
• Experience in installing, integrating, and validating RF hardware subsystems in laboratory environments.
• Experience with laboratory equipment such as VNAs, spectrum analysers, oscilloscopes, and signal generators.
• Excellent organisational skills.
• Structured, analytical working style with strong ownership and execution focus.
• Fluent English.

We value:

• Experience with high-frequency system design.
• Experience with Python or a similar scripting language for data analysis
