Quantum Dice, one of Oxford University’s spinout successes, is an award-winning quantum hardware company. Using the unpredictable quantum nature of light, we have built the world’s fastest quantum random number generator which acts as a key component in encryption or random sampling in computing. We are looking for a skilled, innovative and highly motivated Electronics Engineer with a photonics background to join our team. As a member of the engineering team, you will play a critical part in advancing quantum hardware. Bridging photonics and electronics, you will work on designing, developing and testing solutions integrating photonic and optoelectronic components, including photonic integrated circuits, fibre cables, lasers, drivers, amplifiers, detectors, and associated control electronics. You will be part of a multidisciplinary team to develop technologies from proof-of-concept designs to the product stage across various applications related to cybersecurity and computing. Responsibilities: Design and develop electronic systems and solutions for photonics/optoelectronics, including laser drivers, photodetectors, and control electronics, using design and simulation tools and experimental testing methods. Design solutions for packaging and integration of photonic integrated circuits, including system-in-package designs. Contribute to prototyping, including fibre-optic systems, mechanical/electrical assembly, and optoelectronic testing. Create and execute test plans for functional and environmental qualification of optoelectronic devices, analyse data and refine designs and processes. Requirements: General: 5 years in the electronics/photonics field, with proven expertise in designing and characterising optoelectronic devices in industry or academia. Strong problem-solving skills, an efficient and proactive approach, and the ability to tackle complex technical challenges. Ability to perform in fast-paced environments, work independently, and with great attention to detail. Bachelor’s/Master’s/PhD in Electronics/Photonics/Optoelectronics/Physics or closely related. Electronics: Proficiency in designing analogue and high-speed digital electronics (circuit design and PCB design). Demonstrated experience in circuit design integrating key photonic devices, such as laser diodes, splitters, photodetectors, and amplifiers. Experience with industry-grade PCB design software (e.g. Altium, Cadence Allegro). Photonics: Proven R&D experience in photonics, fibre-based technologies, photonic integrated circuits, packaging, and related material properties. Knowledge within any of these fields: quantum photonics, device characterisation, packaging, semiconductor materials. Benefits: Everyone likes different stuff – that's why we offer benefits tailored to your needs. Let us know what is important to you. In addition, we offer: Flexible working hours and hybrid working arrangements. Holiday entitlement: 33 days. £3,000 benefit allowance to be spent on whatever you like.
