Rigetti Berkeley, United States US$190,000 – US$225,000 pa
Lead a cross-functional team building next-generation superconducting quantum hardware, proposing new technical directions and designing experiments to improve performance and scalability. Own delivery of key quantum technologies, using cryogenic systems, RF and time-domain measurement, and Python to close performance gaps.
Rigetti Berkeley, United States US$165,000 – US$190,000 pa
Lead the mechanical design and integration of cryogenic hardware for quantum computers, including cryostat internals, RF signal delivery and silicon device packaging inside dilution refrigerators. Work spans 3D CAD, FEA thermal/vibrational simulation, prototyping and supplier management, collaborating with quantum physicists and RF engineers.
IonQ Oxford
Owns a group of non-realtime device controllers end to end, from API design and implementation to rollout and operational health, for hardware such as cryogenic compressors, vacuum pumps, lasers and cameras. Controllers are written in Rust on Linux, using gRPC/REST and instrument protocols like SCPI, Modbus, serial and Ethernet, working closely with systems teams and quantum scientists.
IonQ Oxford
Hands-on staff engineering role building and operating the control plane that schedules, calibrates and records work across a fleet of trapped-ion quantum computers. You'll write Rust services handling scheduling, exclusive hardware access, result streaming and data durability, working with runtime, systems and operations teams. Deep diagnosis of live-system failures and setting service boundaries are central.
Infleqtion Kidlington
Develops embedded Linux software, firmware and board-support packages for Xilinx FPGA SoC platforms, using C/C++, Rust, Yocto or Buildroot, plus device-tree configs and low-level drivers. Works with physicists and electronics, FPGA and software engineers on control, acquisition, timing and communications systems for quantum RF sensors, covering board bring-up, integration, automated test and validation.
Universal Quantum Haywards Heath
Hands-on electronics role focused on the hardware system design and realisation of a large-scale control system for quantum computers. Involves analogue and digital circuit design, CAD and test equipment, documentation and verification, plus close collaboration with mechanical engineers, software engineers and physicists on proof-of-concept work.
Universal Quantum Haywards Heath
Lead multidisciplinary systems engineering across electronic, mechanical, cryogenic, vacuum, optical, software and control domains, owning system-level rigour from concept to customer deployment. Define the systems engineering strategy, lifecycle, standards and toolset including requirements management, MBSE, modelling and configuration control, while chairing design, readiness, test and acceptance reviews. Build and mentor engineering teams across UK and international locations, maintaining system-level plans, dependencies and technical risks to meet programme objectives.
PQShield Ideally Tokyo, Japan; Some travel to our offices will be required from time-to-time
Lead sales strategy and execution for a post-quantum cybersecurity company in Japan, targeting enterprise clients in semiconductor, telecom, automotive, and security sectors. Drive market expansion by building relationships with key stakeholders and closing high-value technical IP deals. Collaborate with field application engineers and global teams to align product development with customer needs.
Quantinuum London
A speculative general-interest application rather than a defined role, inviting candidates with an interest or experience in quantum technologies to submit details for future openings. Work spans quantum hardware and software, including quantum chemistry, AI, machine learning/QML, encryption, QNLP and algorithms, across London, Cambridge and Oxford.
PsiQuantum Warrington £31,200 – £56,160 pa
Interns in the optical architecture group work at the interface of hardware, manufacturing and quantum architecture, prototyping software to control and simulate optical networks inside photonic quantum computers. They apply quantum information theory, network design and optimisation to improve designs, simulate and benchmark protocols, and document results. Placements run 3-6 months on a rolling basis, with a mix of analytical and programming work.
Quantinuum London
Develops novel quantum algorithms in computational topology and geometry, characterising resource requirements and noise-robustness, then implementing and optimising them on Quantinuum's quantum hardware using error mitigation and error correction. Works across the full quantum computing stack with hardware, QEC and software teams, and with academic and industry partners on quantum topological data analysis use cases.
PsiQuantum Warrington £99,400 – £116,900 pa
Lead a small team of quantum applications software developers while remaining hands-on, building simulators, resource estimators and circuit compilation pipelines for fault-tolerant quantum computing. The role combines people management with technical delivery, partnering with algorithm researchers and architects to turn quantum algorithms into practical, production-quality tools.
