Job summary

QuantWare in Delft is seeking a mid-level RF Test Infrastructure Engineer to join the hardware R&D team. You will plan and execute RF and DC test campaigns, build scalable measurement infrastructure, and own validation end-to-end from setup to reporting.

You will work with an interdisciplinary team, improve test repeatability and measurement standards, and contribute to characterisation of high-density interconnects and RF links. A hands-on role with cryogenic testing is valued.

Qualifications

• Master’s degree in electrical engineering, applied physics, or a related field.
• 3+ years of experience in test, validation, or characterisation of deep-tech or low-volume hardware.
• Hands-on RF and/or DC measurement with VNAs and SMUs.

Responsibilities

• Test & Validate Devices: Plan and execute RF and DC test campaigns, verifying performance against specifications.
• Build & Scale Measurement Infrastructure: Set up, operate, and maintain room-temperature and cryogenic measurement setups and scale them as needed.
• Investigate & Resolve Anomalies: Diagnose test failures, trace root causes, and feed findings back into device and process improvements.
• Document & Track: Document setups and track process parameters across R&D cycles to build a reusable knowledge base.

Job description

RF Test Infrastructure Engineer at QuantWare, Delft. A mid-level full time position in the Research & Development team, listed under hardware engineering.

Collaboration & Ownership

• Work with a highly interdisciplinary R&D team to align test efforts with development priorities.
• Own validation end-to-end, from setup and sample integration through execution, analysis, reporting, and recommendations.
• Lead initiatives to improve test repeatability, measurement standards, and validation scalability.

Must-haves

• A Master’s degree in electrical engineering, applied physics, or a related field.
• 3+ years of experience in test, validation, or characterisation of deep-tech or low-volume hardware (industry experience is a plus).
• Hands-on experience with RF and/or DC measurement and test methods, and instrumentation such as VNAs and SMUs
• Direct experience working with high-density interconnects, switching matrices, and evaluating RF link budgets (insertion loss, return loss, crosstalk).
• Proficiency in Python and data analysis and visualisation for experiments, and for control and measurement electronics.

What We Offer

At QuantWare, you'll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you'll have the trust, tools, and support to do your best work. Here’s what you can expect: Competitive salary - A salary that reflects the impact and importance of the role (and of course 8% holiday allowance) Pension that is built to last - A generous and future-proof pension plan that includes partner and dependent coverage. Flexibility built on trust - We focus on outcomes.

Responsibilities

• Test & Validate Devices: Plan and execute RF and DC test campaigns for VIO devices and test vehicles, verifying performance against specifications.
• Build & Scale Measurement Infrastructure: Bring up, install, operate, and maintain room-temperature and cryogenic measurement setups, scaling them as R&D needs grow.
• Investigate & Resolve Anomalies: Diagnose test failures, trace root causes, and feed findings back into device and process improvements.
• Document & Track: Document setups and track process parameters across R&D cycles to build a reusable knowledge base.

Nice to Have

• Experience with cryogenic systems such as dilution refrigerators.
• Exposure to transport and microwave characterisation of superconducting circuits - such as critical temperature and current (Tc/Ic), residual resistance, and resonator quality factors (Qi/Qc) via VNA S-parameter measurements is a plus.
