Job description

At OQC, we aren't just theorising about the future; we're building it. Born from a philosophy of bold innovation, we've successfully transitioned quantum computing from an academic dream into a commercial reality. The most exciting thing is that we're just getting started.

The Mission

As a Senior RF Engineer, you will design, develop, and optimise the RF systems that underpin OQC's quantum computing platform. Working at the intersection of cutting-edge hardware, systems engineering, and quantum technology, you'll solve complex RF challenges that improve the performance, reliability, and scalability of our quantum computers.

The Role

You'll be a technical specialist within our Advanced Product Development team, leading the design and validation of RF and microwave solutions that enable quantum control and readout. Working closely with multidisciplinary engineering teams, you'll take ownership of RF hardware development from concept through to deployment, helping shape the future of commercially viable quantum computing.

What You'll Be Working On

• Architecting and delivering RF control, readout, and packaging solutions that meet demanding system performance requirements
• Designing, simulating, testing, and optimising RF and microwave circuitry using modelling tools and laboratory-based experimentation
• Leading RF characterisation activities, including microwave I/O analysis, filtering design, signal-to-noise optimisation, and performance validation
• Investigating complex technical issues, driving root-cause analysis, and implementing data-led design improvements
• Collaborating with hardware, systems, and cryogenic engineering teams to ensure successful integration across the quantum computing stack
• Managing technical engagement with RF suppliers, evaluating components, and supporting hardware quality assurance activities
• Providing technical leadership, mentoring engineers, and contributing to roadmap planning, delivery forecasting, and engineering best practices

What We're Looking For

• Proven experience developing RF and microwave hardware solutions
• Strong RF design, simulation, and modelling expertise
• Experience with RF laboratory testing, validation, and characterisation methodologies
• Demonstrated ability to solve complex technical and system integration challenges independently
• Experience working across multidisciplinary engineering environments
• Strong data analysis, stakeholder communication, and technical documentation skills
• Ability to balance technical trade-offs, risk, manufacturability, and performance requirements
• Experience engaging with suppliers and technical partners
• Technical leadership capability, including project ownership and mentoring of engineers
• Degree in Electronics, Physics, Engineering, or a related discipline, or equivalent practical experience

The \'Nice-to-Haves\'

• Postgraduate qualification in RF Engineering, Microwave Engineering, Electronics, Physics, or a related discipline
• Experience leading complex technical projects or work packages
• Experience within advanced technology, research, or highly regulated environments
• Knowledge of project planning, risk analysis, and process improvement methodologies
• Python scripting experience
• Strong influencing, adaptability, creativity, and leadership skills

Why Join OQC

You will join a world-class team at the forefront of the next computational era. We offer a culture of bold innovation, the chance to work with unique lab infrastructure, and the opportunity to see your work redefine the limits of computation.
