About Us

QuantWare is the world's leading manufacturer of superconducting quantum hardware. As a hyper-growth scale-up with a global customer base, our mission is to accelerate the advent of the quantum computer. We push the boundaries of what's possible in our field. We work on making the world's largest quantum processors as fast as possible.

At QuantWare, we're not just producing quantum hardware for the hyperscalers of tomorrow; we're working on technology that will change the world. To make that ambition a reality, we need exceptional people who drive real impact. That's where you come in.

QuantWare is seeking an Experimental Quantum Engineer to join our growing Operations team. The mission of QuantWare's Operations team is to consistently deliver high quality quantum hardware and make advanced quantum technologies accessible to customers all over the world.

Together with your colleague Experimental Quantum , you will be in charge of several state of the art cryogenic setups. You'll use these setups to perform advanced qubit measurements and guarantee the quality of all devices before they are shipped to customers. Whenever you spot abnormalities, you'll search for root causes and countermeasures, together with your colleagues from Fabrication or Design. Product volume and complexity of our products increase - so the challenge is to stay one step ahead by continuously improving our measurement setups, software and processes.

Key Responsibilities:

• Own QuantWare's cryogenic measurement setups: purchase and build them, and keep them state-of-the-art (maintenance, upgrades).

• Manage the hands-on physical operation of cryogenic quantum hardware, working directly with the dilution refrigerators.

• Develop measurement code to implement and refine Python-based routines for device characterization.

• Characterize quantum chips to evaluate and improve the performance of superconducting qubits and amplifiers - to guarantee QuantWare's customers receive perfect devices and to support new product development and research.

Job Requirements:

• Education: master's degree in physics or electrical engineering, preferably with a focus on quantum computing.

• Experience: Hands-on experience with programming, preferably Python.

• Knowledge: Experience with superconducting circuits and microwave measurement techniques is a plus, but not required.

• Skills: you are tech-savvy, learn fast and get things done: regardless if that means getting your hands dirty or deep in the python code. You enjoy solving problems and methodically improving our processes.

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 competitive monthly salary, plus an 8% annual holiday bonus paid out each May

Pension that's built to last - A future-proof pension plan that includes partner and dependent coverage. QuantWare covers 63% of the premium
