Systems Engineer

As a highly skilled Systems Engineer for Quantum & Cryogenic Systems in the System Engineering team at Delft Circuits you will work at the intersection of electrical engineering, mechanical engineering, cryogenics, and quantum computing, playing a key part in the design, integration, and optimization of complex I/O systems for quantum computing. You will collaborate with multidisciplinary teams to develop reliable, scalable solutions for cryogenic quantum hardware and system-level architectures and provide technical support to our Sales team.

At Delft Circuits, we’re pushing the boundaries of cryogenic electronics with our flagship Cri/oFlex® platform—the world’s first fully integrated cryogenic I/O solution for quantum computing. Based in Delft, Netherlands, our diverse team of engineers, physicists, and innovators combines deep technical expertise with an open, collaborative culture — where ideas are shared, challenges are tackled head-on, and impact is real.

Your key responsibilities will include:

• Lead the multidisciplinary projects for system-level design and integration of quantum hardware: high-density wiring and cryogenic infrastructure around it
• Translate high-level requirements into functional system architectures and technical specifications
• Design and validate electrical, mechanical, and thermal interfaces
• Develop and maintain block diagrams, interface control documents (ICDs), and system requirements
• Perform system-level modeling, simulations, and trade-off analyses
• Support hardware development including:
  • Cryogenic systems and thermal design
  • RF and signal integrity considerations
  • Mechanical design and packaging
• Coordinate testing, debugging, and verification activities from prototype to product level
• Identify system risks and implement mitigation strategies
• Provide technical guidance to junior engineers
• Collaborate closely with physicists, hardware / R&D engineers, and production teams
• Support system-level documentation and product qualification

What you bring:

• Master’s or PhD in Electrical Engineering, Mechanical Engineering, Applied Physics, Systems Engineering or a related technical field
• Strong understanding of at least two of the following:
  • Cryogenic systems
  • Quantum hardware
  • RF engineering
  • Mechanical design for precision systems
  • Thermal engineering
• At least three years of experience in high tech industry and working with complex multidisciplinary system designs
• Familiarity with system engineering methodologies
• Hands-on experience with test setups, diagnostics, or troubleshooting of hardware systems
• Ability to manage complexity and communicate clearly across disciplines
• Proficiency in documentation and technical reporting
• Prior customer facing experience

Nice-to-Have Qualifications

• Experience with quantum computing platforms (superconducting qubits, cryogenic electronics, or quantum interconnects)
• Knowledge of:
  • Cryostats and dilution refrigerators
  • Low-noise electronics
  • Vacuum systems
  • RF design and measurement
• Experience with tools such as:
  • MATLAB / Python
  • CAD software (e.g., Fusion 360, Inventor, or similar)
  • Simulation tools (ANSYS, COMSOL, CST, etc.)
• Previous experience in high-tech R&D or semiconductor environments
