IonQ’s newest generation of quantum computers, the IonQ Tempo, is the latest in a line of cutting-edge systems that have been helping customers and partners including Amazon Web Services, and AstraZeneca achieve 20x performance results and accelerate innovation in drug discovery, materials science, financial modeling, logistics, cybersecurity, and defense. In 2025, the company achieved 99.99% two-qubit gate fidelity, setting a world record in quantum computing performance . Headquartered in College Park, Maryland, IonQ has operations in California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom. Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. Role At Oxford Ionics, now part of IonQ, we are building the first practical quantum computer. Our systems are based on ion traps, which hold individual atomic ions tens of microns above the surface of a chip, and we design and build them in house, bringing together optomechanics, vacuum and cryogenic technology, electronics and system infrastructure. We are looking for a Senior Mechanical Engineer to join our Systems team and take ownership of mechanical design from first requirements through to manufacture and integration. You will work on the hardware that surrounds the quantum processor, including cryostat requirements, cooling equipment, vacuum chambers and supporting structures, often in areas where the requirements are not yet fully defined. Responsibilities: You will work alongside scientists, technicians and the wider hardware design teams to bring new systems through to manufacture. That means producing CAD designs, bills of materials and assembly drawings, managing documentation in our PLM system and working with suppliers and our manufacturing team. Our ma
