Job description

Help create the products for Cryogenic Quantum Control

Quantum Machinesis a global leader in hybrid control systems for quantum computing, a field on the verge of exponential growth. Our innovative hardware and software offer a groundbreaking approach to controlling quantum computers, scaling from individual qubits to arrays of thousands. At the heart of QM is a passionate, ambitious team committed to transforming the construction and operation of quantum computers. Our deep understanding of customer needs drives us to deliver unmatched solutions in this revolutionary field.

Quantum Machines isestablishinga dedicated Cryogenic Control team as part of ourCryoProduct Line. We are looking for aDevelopment Engineer with a strong background in electronics development, ideally with experience in IC validation, RF/mixed-signalelectronicsor semiconductor applications.

This is an opportunity to work at the intersection of quantum technology, cryogenic electronics, semiconductordevelopmentand advanced hardware engineering. You will help turn emerging technologies into products that solve real scaling challenges for quantum-computing customers.

As a Development Engineer in Cryogenic Control, you will help create and integrate the products defined in our product strategy and contribute to the development of Quantum Machines’ cryogenic control electronics activities. You will evaluate semiconductor technologies and supplier offerings and develop their integration into our large-scale solutions for quantum chip packaging.

A keyinitialobjectivewill be toparticipateinidentifying,evaluatingandproductisingcryogenic multiplexer technologies together with the associated carriers,packagesand test infrastructure.

You will work closely with quantum physicists, electronics engineers, packaging specialists, semiconductor partners,foundriesand suppliers.

The role requires an engineer who can understand the system-level requirements, translate them into practical hardwaresolutionsand help drive emerging technologies toward reliable products with a fast time to market.

Key Responsibilities

• Develop and integrate cryogenic control electronics into Quantum Machines’ quantum chip carrier solutions.
• Evaluate and characterize cryogenic ICs and technologies from semiconductor partners and suppliers.
• Design PCBs, testsubstratesand electrical interfaces for cryogenic electronics.
• Develop and execute electrical and cryogenic characterization and validation.
• Work with IC,packagingand quantum specialists to turn emerging technologies into robust product solutions.

Requirements

We expect you to have:

• A strong foundationin electronic engineering or applied physics.
• Hands-on experience with electronic hardware development,testand validation.
• Experience with ICs, mixed-signal, RF/microwaveelectronicsor semiconductor applications.
• Experience designing PCBs, testhardwareor electronic interfaces.
• Strong experimental and measurement skills.

Experience withcryogenic electronics, quantum-controlsystemsor semiconductor packagingis highlyvaluable, butnotrequired.

Experience from a commercial technologyorganisationis an advantage. You may currently work in electronics development, semiconductor applications, IC validation, productdevelopmentor advanced hardware engineering.

Previousexperience with quantum or cryogenic systems is an advantage, but we expect the right engineer to learn the application domain as part of the role.

What You Bring

• Strong engineering judgement and a hands-on approach to hardware development.
• The ability to turn concepts into prototypes,measurementsand working solutions.
• Strong experimental and data-driven problem-solving skills.
• System-level thinking across ICs,electronicsand packaging.
• Pragmatic engineering,balancingperformance, reliability,manufacturabilityand speed.

Experience with fabless semiconductor development, foundry processes, technology transfer, semiconductorpackagingor outsourced manufacturing would be an advantage.
