Validation Engineer

Quantum Machines (QM) is a global leader in control systems for quantum computing, a field on the verge of exponential growth. Our innovative hardware and software mark a groundbreaking approach in quantum computer control, scaling from individual qubits to expansive arrays of thousands. At the core of QM lies a passionate and ambitious team committed to reshaping the construction and operation of quantum computers. Our work is fueled by a deep understanding of customer needs, driving us to deliver unparalleled solutions in this revolutionary field.

The hardware development team spans two global sites – one in Tel Aviv and one in Copenhagen. The team is responsible for all hardware within QM spanning from room-temperature control hardware to our cryogenic QPU carriers.

We are looking for a Validation Engineer or Physicist to plan and execute validation activities for cryogenic hardware, with a strong focus on electrical and RF performance. In this role, you will work closely with system architecture, RF, mechanical, and hands-on engineering functions to translate design intent and requirements into validated, production-ready solutions. The position combines structured test planning, shared technical risk ownership, and hands-on execution in laboratory and cryogenic environments.

Key Responsibilities

• Define validation strategies, test plans, and acceptance criteria aligned with system and customer requirements.
• Contribute to customer-facing compliance matrices and quality planning.
• Take ownership of Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT).
• Report on test results and provide clear, actionable feedback to development teams and customers.
• Design, build, and maintain electrical and RF test setups, fixtures, and measurements.
• Contribute to technical risk analysis at the project level, defining validation and mitigation activities in collaboration with the project team.
• Plan and execute proof-of-concept (POC) validation activities, with emphasis on electrical and RF performance.
• Perform cryogenic testing, including preparation, operation, data collection, and analysis.

Requirements

Required Qualifications:

• BSc or MSc in Electrical Engineering, Physics or a closely related field.
• Hands-on laboratory experience with electrical measurements, including DC and RF systems.
• Experience in planning and executing structured validation experiments including reporting to customers.
• Ability to translate system and customer requirements into measurable validation activities.
• Strong analytical skills with attention to data quality and repeatability.
• Ability to work independently while collaborating closely with cross-functional teams.
• Clear and effective communication skills.
• Basic knowledge of metrology and quality assurance in measurements.

Travel

• Occasional travel may be required to support cryogenic testing and validation activities.

Preferred Skills

Preferred Qualifications

• Experience supporting FAT/SAT or customer-facing acceptance testing.
• Experience with cryogenic systems or low-temperature electrical measurements.
• Experience with compliance matrices and validation planning.
• Experience working in multidisciplinary teams combining physics and engineering.

What We Offer

A hands-on engineering role with meaningful technical ownership, focused on validating complex electrical and RF systems. You will influence design decisions through risk-driven validation and help bring advanced systems from development to compliant and reliable operation.
