Job summary

Groove Quantum in Delft is seeking a hands-on hardware engineer to design, build, and test analogue, RF, and mixed-signal hardware, spanning the entire signal chain from cryogenic packaging to room-temperature electronics.

You will perform thermal and noise calculations, build models, and conduct lab characterisations to trace and eliminate performance bottlenecks. Collaboration with measurement, fabrication, software, and electronics teams is essential.

Qualifications

• Education: MSc or PhD in electrical engineering, applied physics, or a related field.
• Hardware design: Experience designing, building, and characterising analogue, RF, or mixed-signal hardware, including knowledge of noise, signal integrity, filtering, and PCB design.
• Cryogenics: Familiarity with cryogenic systems, or a strong drive to master low-temperature engineering.
• Quantitative & lab skills: Strong analytical ability to build quantitative hardware models, backed by enthusiasm for hands-on assembly, lab measurements, and testing.
• Pragmatic execution: Ability to work independently, escalate when necessary, and apply CAD/RF layout tools or device physics concepts to practical engineering problems.

Responsibilities

• Hardware development & testing: Design, build, and test analogue, RF, and mixed-signal hardware across the signal chain from concept through to a working assembly.
• Lab characterisation: Characterise hardware performance in the lab, from individual low-temperature components up to the fully integrated signal chain.
• Modelling & calculations: Perform noise, thermal, and signal integrity calculations/simulations, contributing empirical data to overall system budgets.
• Performance investigation: Trace and investigate hardware performance limitations across the chip, package, signal chain, or instrumentation.
• R&D integration & documentation: Document designs and findings to inform future architectural decisions while collaborating with measurement, fabrication, software, and electronics teams.
