Validation Engineer

we are 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 our company 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 our company 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.
