Quantum Computing Jobs

Universal Quantum · Haywards Heath

Provide optical engineering support to a team developing commercial trapped-ion quantum computers. Design, assemble, align and characterise laser and optical subsystems, integrate fibre-optic and opto-mechanical assemblies, and develop test methods to improve alignment stability and throughput. Work alongside electronics, mechanical, physics and quantum engineers.

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.

IonQ · Oxford

This role involves working closely with software engineers, systems teams, and quantum scientists to build and operate the software that controls the hardware surrounding quantum computers. Responsibilities include designing and implementing device controllers, ensuring robustness and observability, and integrating with the wider software architecture.

IonQ · Oxford

Join the Runtime Software team to build the real-time control system that turns quantum hardware into a working computer. You'll develop Rust libraries and abstractions over real-time control devices, driving ions with nanosecond precision, and work closely with experimental scientists and compiler teams.

Rigetti · Berkeley, United States · US$180,000 – US$230,000 pa

Owns end-to-end deployment of quantum computing systems both on-premises at customer and partner sites and on the cloud platform, acting as the technical point of contact from site requirements through installation, validation and handoff. Combines DevOps work — Kubernetes, AWS, Terraform, CI/CD, observability — with on-site commissioning, SRE support and root-cause analysis, with international travel and on-call during installations.

Rigetti · Berkeley, United States · US$190,000 – US$240,000 pa

Hands-on role owning networking and physical infrastructure across Berkeley labs and a Fremont fabrication facility, including routing, racking, cabling, switches, firewalls and storage, while also supporting AWS cloud environments and infrastructure-as-code. The engineer flexes between data center work and cloud/DevOps tasks such as Terraform, Kubernetes and CI/CD, building new infrastructure as lab and fab space expands.

PQShield · Remote (within the countries we operate from); UK, France, Netherlands, Spain, or Belgium. Some travel to our offices will be required from time-to-time

Lead a cryptographic software IP team, owning the full development lifecycle from architecture and planning to testing and customer delivery. Combines hands-on embedded C expertise with line management, hiring, mentoring and cross-team strategy, working on post-quantum cryptography and RISC-V with hardware and vulnerability teams.

PQShield · Remote (within the countries we operate within; Some travel to our offices will be required from time-to-time

Owns the product roadmap for software-based security IPs, cryptographic libraries and firmware, defining how security software integrates with hardware IPs and SoC architectures. Acts as domain expert on classical and post-quantum cryptography, hardening products against side-channel, DPA and timing attacks, and authoring PRDs that translate crypto standards into engineering requirements. Works directly with founders and customers in a deep-tech semiconductor context.

Quantinuum · London

Registering interest for ad-hoc internship positions lasting 3-6 months, mostly focused on specific projects or client collaborations rather than a formal summer programme. Work areas span quantum software development, chemistry, machine learning, algorithms, cybersecurity/encryption and hardware, with candidates ideally holding or pursuing a Master's or PhD.

IonQ · Oxford

Owns full-chip mixed-signal modelling and verification for cryo-CMOS ASICs used in trapped-ion quantum processors, building Verilog-A/AMS and real-number SystemVerilog models correlated against schematic and measured silicon. Leads AMS methodology, sign-off criteria and reviews, runs Cadence AMS/Xcelium-Spectre co-simulation and regressions, and mentors engineers through tape-out and silicon bring-up.

IonQ · Oxford

Lead end-to-end delivery of quantum computing systems to customer sites across Europe and Asia, owning deployment and commissioning from early planning and export through installation, commissioning and handover. Coordinate engineering, science, legal, trade compliance, logistics, facilities, security and customer teams, with around 30-40% travel.

IonQ · Oxford

Owns the full lifecycle of electrical reliability fixes on operational trapped-ion quantum computers, from triaging and root-causing control and drive-electronics faults to designing, prototyping and retrofitting permanent solutions. Works across Operations, Science and Manufacturing on fleet-wide upgrades, standardising hardware and building telemetry to cut downtime.

IonQ · Oxford

Integrate all features needed to operate quantum computers into complex multi-layer ion-trapping chips, taking designs from requirements through layout and tape-out. Work closely with scientists and fabrication engineers, handling metal-track routing and interfaces with photonics and CMOS, and independently owning project delivery.

IonQ · Oxford

Builds the control plane that schedules quantum programs, calibration routines and customer workloads onto trapped-ion hardware, arbitrating exclusive access and streaming results. Owns persistence, data models and migrations, plus tests and harnesses run against real machines and simulators. Works in Rust, PostgreSQL and gRPC alongside runtime, systems and operator teams.

IonQ · Oxford

Architect, develop and maintain advanced UVM/SystemVerilog verification environments for complex FPGA designs, defining verification plans with constrained-random testing and functional coverage. Build automated regression suites and CI pipelines, and debug issues with RTL designers to support quantum control systems.
