Quantum Computing Jobs

Universal Quantum · Haywards Heath

Designs and simulates quantum error correction protocols, tailoring them to hardware strengths and characterising physical qubit noise profiles. Performs resource estimation for large-scale applications and advises on hardware and software control choices to optimise error correction performance in the near and far term.

Pasqal · London

Develops and benchmarks quantum error-correcting codes and fault-tolerant protocols tailored to neutral-atom hardware, including decoder design, logical error models and error budgets. Builds and maintains QEC simulation and emulation tools, analyses experimental data, and provides QEC-driven inputs to future QPU architecture design. Involves writing technical reports and scientific articles and representing the company at international conferences.

Infleqtion · Kidlington

Designs, analyses and implements fault-tolerant architectures for scalable quantum computation, developing error-correcting codes, decoders and fault-tolerant gate constructions tailored to neutral atom hardware. Works with hardware, control and compiler teams to model noise, optimise syndrome extraction and define logical performance metrics, bridging QEC theory and experimental implementation.

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.

Quantinuum · London · £2,500 pm

Interns join the UK Quantum Error Correction team to work on an active research project spanning architectural design, analysis and implementation of the QEC stack, from tensor networks and ZX calculus to fault-tolerant magic state gadgets and trapped-ion demonstrations. Based in London or Cambridge, the role sits in a research-focused group with close ties to hardware and software engineers, aiming at a publication and/or software libraries.

Rigetti · Berkeley, United States · US$220,000 – US$250,000 pa

Lead a cross-functional software engineering team building platforms for quantum device design, chip fabrication workflows, physics-informed data analysis, and QPU characterization. The role is hands-on, spanning team management, architecture, and data pipeline work with Python, AWS, and streaming tools, while partnering closely with quantum hardware, fabrication, and research teams.

Rigetti · Berkeley, United States · US$175,000 – US$200,000 pa

Lead experimental programs to characterize, calibrate and optimize two-qubit gates on tunable-coupler superconducting processors, isolating error sources such as leakage, crosstalk and decoherence. Develop pulse shaping, dynamical decoupling and automated calibration methods that scale across hundreds of qubit pairs, feeding findings back into device design and fabrication.

IonQ · Oxford

Validates and optimises trapped-ion quantum computers, prototyping coherent control and cooling schemes, calibrating and benchmarking qubit gates, and validating emerging trap technologies with integrated electronics and photonics. Involves coding and debugging experiments in Python or Rust and documenting findings within a fast-moving UK science team.

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.

University of Exeter · Exeter · £21,805 pa

A 3.5-year PhD modelling nonlinear quantum optomechanical devices, focusing on suspended graphene resonators coupled to superconducting microwave cavities. The student develops analytical and numerical models of device dynamics, examines limitations like parasitic coupling and decoherence, and designs protocols for non-classical mechanical states, working with theorists and experimentalists.

University of Sussex · Brighton · £51,753 – £56,535 pa

Lead a Knowledge Transfer Partnership project to commercialise an optical atomic clock, working across CPI TMD Technologies and the University of Sussex. Day to day involves reviewing and redesigning atomic clock subsystems, sourcing components and suppliers, and testing, characterising and integrating the full system through a gate-stage new product introduction process.

Infleqtion · Kidlington

Designs, implements and optimises quantum algorithms for simulation, optimisation and hybrid quantum-classical workloads, working with hardware, control and research teams to turn theory into executable applications. Deploys software optimisations to the Superstaq cloud platform using industry-grade engineering practices, supports customers, and contributes to research publications and commercial proposals.

University of Strathclyde · Glasgow · £47,389 – £58,225 pa

Lead the commercial development of a compact cold-atom clock physics package, translating university research into a viable product. The role is based at CPI-TMD in Hayes after an initial 8-12 month placement at the University of Strathclyde, working with academic researchers and industrial engineers.

Universal Quantum · Haywards Heath

Operate, monitor and maintain ion-trap quantum computing hardware and experimental systems, running calibration, optimisation and characterisation of quantum hardware and control systems. Work closely with physicists and engineering teams to integrate and test new hardware, collecting and analysing experimental data to support performance and troubleshooting.

PsiQuantum · Warrington · £78,900 – £92,900 pa

Translate computational tasks into abstract quantum-algorithm specifications, analyse asymptotic performance, and define problem instances beyond classical reach. Work with the Compilation team on explicit implementations and resource estimates, and lead research programs with industrial and academic partners across domains such as life sciences and sustainability.
