Photonics Design Engineer

Contract Type: Full-time, Permanent Location: Cambridge, UK Visa Sponsorship available Join Nu Quantum - Shaping the Future of Technology Nu Quantum is at the forefront of quantum computing and advanced technology, driven by innovation, diversity, and a commitment to excellence. We’re creating an environment where brilliant minds from all backgrounds collaborate to push the boundaries of what’s possible. Founded to commercialise research generated over the last decade at the Cavendish Laboratory, Nu Quantum is on a mission to shape the future of quantum information systems. We’re working on exciting technology that will improve the utility and accelerate the time-to-market of quantum computing systems. We integrate novel quantum photonic technology to form an efficient and scalable quantum networking infrastructure in partnership with world-leading companies and academic groups. About the role As a Photonic Design Engineer within Nu Quantum’s Photonic Integrated Circuit (PIC) team, you will work towards advancing our quantum networking technology by designing and optimising integrated photonic components critical to our scalable quantum systems. You will work with cutting-edge quantum photonics and advanced photonic integration technologies to develop innovative PIC designs that meet the stringent performance, reliability, and manufacturability requirements of quantum hardware. You will collaborate closely with our quantum photonics scientists, fabrication partners, packaging engineers, and test teams to drive the development of robust photonic building blocks such as waveguides, couplers, modulators, and switch networks. This is an exciting opportunity to be part of a pioneering company at the forefront of quantum photonics innovation. What You'll be doing Design and develop passive and active photonic components such as waveguides, couplers, interferometers and switches using design & simulation tools such as Lumerical and GDSFactory and any other existing state-of-the-art tools to complement them. Perform detailed simulations and modelling of integrated photonic circuits. Collaborate closely with fabrication teams and foundries to ensure design-for-manufacture compatibility and to troubleshoot fabrication issues. Develop and maintain design libraries, PDKs (Process Design Kits), and documentation for repeatable and scalable device design. Analyse experimental data from device testing to validate models and improve designs iteratively. Work-cross functionally with test engineers, system architects and external partners to develop a fully integrated switch network. Communicate technical progress, risks, and results clearly to internal and external stakeholders. Requirements Essential Postgraduate-level qualification in Photonics, Optical Engineering, Electrical Engineering, or related field. Proven experience in photonic device design and simulation, preferably for silicon and silicon nitride, lithium niobate, or III-V…
