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.

You will define the electronic architectures that power scalable quantum computing systems. You'll solve complex system-level challenges spanning high-speed electronics, synchronisation, integration, and manufacturability, helping to deliver the next generation of quantum control hardware.

The Role

As a senior technical leader within our Control Hardware team, you'll drive the architecture, design, and delivery of highly integrated electronic systems that enable high-performance qubit control, deterministic synchronisation, and data acquisition across distributed quantum computing platforms. You'll work closely with multidisciplinary engineering teams, influence long-term hardware strategy, and provide technical leadership across the organisation.

(internally this role is called a Staff Electronic Design Engineer)

What You'll Be Working On

About the Company

Oxford Quantum Circuits

Develops superconducting quantum computers and services

Oxford Quantum Circuits (OQC) is a UK quantum computing company that builds superconducting quantum systems using its Coaxmon architecture and offers Quantum Computing as a Service through cloud access and colocated data centers. Its products work by using superconducting qubits implemented with the Coaxmon design, allowing users to run quantum programs remotely via a cloud interface or at partner data centers, with plans for larger TITAN systems aimed at fault-tolerant computing. What sets OQC apart from competitors is its specific Coaxmon architecture and its focus on scaling up infrastructure across international locations, backed by a large Series C funding round and strategic investors, to push toward practical, fault-tolerant quantum computing. The company’s goal is to expand its global infrastructure and develop next-generation TITAN quantum systems to achieve fault-tolerant quantum computing at scale.
