RF Engineer
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 and we’ve recently closed our £260 million Series C funding round – the largest fundraise ever completed by a quantum computing company in Europe.
The Purpose
As an RF Engineer, you'll design, develop and optimise the RF solutions at the heart of OQC's quantum computing systems. Combining passive RF and PCB design expertise with microwave simulation, prototyping and hands-on testing, you'll create robust control and readout solutions that enable both cutting-edge R&D and the deployment of commercial quantum computers.
The Role
Working within our Advanced Product Development team, you'll take RF solutions from requirements and simulation through prototyping, characterisation and deployment. You'll design RF circuitry, PCBs and packaging, optimise microwave performance and work across hardware teams to ensure solutions integrate successfully into OQC's wider technical stack.
This is a hands-on engineering role where you'll combine deep RF knowledge with practical design and testing, owning technical decisions and continuously improving the performance of our RF systems.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Be Working On
- Design and develop passive RF/microwave circuitry, PCBs and packaging for quantum control and readout systems.
- Translate engineering requirements into RF designs that deliver the required signal performance while managing electromagnetic interference.
- Simulate, prototype and characterise RF solutions using microwave analysis tools, FEA, electromagnetic (EM) tools and laboratory instrumentation.
- Optimise signal integrity, signal-to-noise performance, filtering and microwave I/O performance through iterative design and testing.
- Analyse test results and independently identify opportunities to improve existing RF designs, components and testing approaches.
- Own RF solutions through technical validation, documentation, supplier engagement and handover into OQC's live quantum computing systems.
- Collaborate across hardware, engineering and supply chain teams, providing RF expertise and supporting technical installations in the UK and internationally.
What We're Looking For
- Strong practical experience working with RF and microwave technology, ideally in the 4-10 GHz range
- Hands-on experience designing passive RF systems and components, alongside PCB design experience.
- Strong understanding of RF/microwave principles, theory and design techniques.
- Experience designing, simulating, prototyping and testing RF or microwave circuitry and systems,
- Experience using electronic design, FEA, electromagnetic (EM) simulation, and microwave analysis tools.
- Ability to gather technical requirements, translate them into practical designs and clearly communicate design progress and results.
- Strong analytical and problem-solving skills, with the ability to use experimental data to drive design improvements.
- Bachelor's degree or higher in Electronics or a related discipline.
