Cryogenic RF Engineer; Intermediate or Senior

About the role

D-Wave is seeking a Cryogenic Radio Frequency (RF) Engineer to join our Electrical Engineering team to develop cutting-edge cryogenic RF systems for quantum computing. In this role, you will collaborate with quantum processor scientists, superconducting IC designers, and multidisciplinary engineering teams to design, test, characterize, and optimize cryogenic RF hardware that enables next-generation quantum computers.

Depending on your experience and demonstrated expertise, you will contribute as either an Intermediate or Senior Engineer. The successful candidate will be hired at the level that best aligns with their qualifications, experience, and technical impact.

• Design, develop, test, and characterize cryogenic RF networks, including transmission lines, filters, interconnects, and related hardware.
• Model, simulate, analyze, andoptimizeRF performance using measurement and simulation tools.
• Develop validation plans, perform laboratory testing, troubleshoot technical issues, and implement design improvements.
• Select materials and manufacturing approaches for PCBs, flexible cables, and interconnectsoperatingin cryogenic environments.
• Collaborate with scientists, IC designers, and cross-functional engineering teams to integrate RF systems into quantum computing platforms.
• Partner with external vendors to support prototype development and production activities.
• Contribute to continuous improvement of RF designs, test methodologies, and engineering processes.

• Master’s degree or PhD in Electrical Engineering, Applied Physics, ora related field with relevant industry, research, or equivalent experience.
• Strong knowledge of RF/microwave engineering, including passive devices, transmission line theory, S-parameters, and signal integrity.
• Experience with RF test equipment, including vector network analyzers, spectrum analyzers, oscilloscopes, arbitrary waveform generators, and time-domain reflectometers.

• Understanding ofRF noise analysis and modeling.
• Programming experience (Python, Julia, C/C++, or similar).

You are developingexpertisein cryogenic RF engineering and contribute to the design, testing, and optimization of RF hardware. You independently complete routine work, solve moderately complex technical problems, and contribute to project deliverables while receiving guidance on new or larger initiatives.

• Contribute to the design, testing, characterization, and troubleshooting of cryogenic RF systems.
• Execute defined technical work streams with moderate independence.
• Analyze technical problems and recommend solutions with support from senior engineers when needed.
• Collaborate effectively within cross-functional engineering teams.
• Continuously expand technicalexpertisewhile contributing to process and design improvements.

You are an experienced RF engineer who independently leads technical work, solves complex engineering challenges, and influences RF system design. You provide technical leadership across projects while mentoring others and driving continuous improvement.

• Lead the design, development, validation, and optimization of cryogenic RF hardware and subsystems.
• Independently manage projects of moderate complexity and make sound technical decisions withinprojectscope.
• Drive root cause investigations, design improvements, and engineering best practices.
• Collaborate across teams to influence technical direction and system architecture.
• Mentor junior engineers and contribute to technical knowledge sharing across the organization.

• We look at the future and say “why not”; we see possibilities where others see problems or routines. We show the way ahead and are committed to…
