Quantum Computing Jobs

IonQ · Oxford

Builds and runs the Kubernetes-based platform behind IonQ's quantum systems, spanning on-site clusters and cloud infrastructure. The role covers CI/CD pipelines, observability for lasers, cryogenics and vacuum hardware, remote development environments, and infrastructure as code with OpenTofu. It involves leading strategic platform projects and working closely with physicists, lab technicians and SRE colleagues.

IonQ · Oxford

Lead end-to-end delivery of the Systems Software roadmap across five engineering teams (runtime, orchestration, quantum tools, controllers, transport) for concurrent next-generation quantum system programmes. Own planning, dependency management, risk surfacing and status reporting, working with hardware, science and US-based teams to make capacity decisions explicit.

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.

PsiQuantum · Warrington

Develops scalable fibre-to-chip alignment schemes and opto-electronic packaging workflows for chip-based photonic integrated circuits at the UK R&D facility in Daresbury. Involves prototyping packaging flows, reviewing BOMs, sourcing materials with supply chain and external vendors, and transferring designs to manufacturing partners.

Rigetti · Berkeley, United States · US$240,000 – US$275,000 pa

Lead the global deployment, integration and commissioning of on-premise quantum computing systems, building and scaling a Field Engineering organisation. Own site readiness, installation, acceptance and lifecycle support for superconducting processors, dilution refrigerators and RF/microwave hardware, acting as senior technical escalation point and travelling globally around 30-40%.

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.

Rigetti · Berkeley, United States · US$160,000 – US$190,000 pa

Owns end-to-end delivery of complex quantum systems programs, building roadmaps, milestones and integration schedules across device fabrication, cryogenics, control hardware and software teams. Tracks readiness across hardware, firmware and software layers, manages cross-team dependencies and risks, and establishes scalable program management practices for research-driven deep-tech R&D.

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.

IonQ · Oxford

Lead validation and characterisation of analogue and mixed-signal ASICs for trapped-ion quantum processors, from test planning and platform development through first-silicon bring-up, debug and system integration. The role spans room-temperature and cryogenic (around 4 K) measurements on packaged parts, chip-on-board assemblies and bare die, with heavy Python automation and test PCB work.

IonQ · Oxford

Build and lead a team owning the hardware test estate for quantum-computer control software, from CI systems to new QA and staging rigs. Define test-system architecture, plan builds with Manufacturing, and shape testing strategy across simulation and hardware-in-the-loop. Act as test architect, driving automation and self-service rig usage.

IonQ · Oxford

Inspects incoming, in-process and finished components against mechanical, electrical and PCBA specifications, interpreting GD&T drawings and programming CMM, OMM or vision systems. Owns the inspection side of the Material Review Board, controlling nonconforming material and closing NCRs, while allocating daily work and guiding less experienced inspectors.

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.

Universal Quantum · Haywards Heath

Design, model and test waveforms that transport ions quickly and efficiently on surface ion traps, including inter-module connections via UQConnect. The role also involves contributing to ion trap designs, building accurate physics models and optimisation software, and working with hardware teams to implement transport methods and analyse experimental results against predictions.

IonQ · Oxford

Leads the evolution of the system software architecture for a quantum computer, spanning real-time hardware control, low-level orchestration and developer-facing interfaces across a family of products. Coaches technical leads in architectural principles and coordinates with infrastructure, firmware and compiler teams in the UK and US, working at system level rather than designing through code.

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.
