Lead the software engineering strategy and a team building post-quantum cryptography products, from cryptographic libraries and secure protocols to embedded, cloud and data centre deployments. The role spans architecture, Agile delivery, CI/CD and secure development practices, working closely with cryptographers and hardware engineers on hardware-software co-design.

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.

Quantinuum · London · US$179,000 – US$241,000 pa

Acts as technical authority for a quantum software developer platform, owning the design of access portals, hybrid workflow orchestration, tooling, documentation and security. Works with hardware-software co-design leaders to keep the platform scalable, mentors senior engineers, sets coding standards and drives the technical roadmap.

Quantinuum · Cambridge

Leads engineering teams building core quantum languages, compilers and toolkits such as Selene, TKET, HUGR and Guppy, balancing people management with technical roadmap execution. Stays hands-on through design discussions, architectural reviews and code problem-solving, and guides tooling from research prototypes to production-grade software. Collaborates with hardware, theory and product teams across global sites, with occasional international travel.

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.

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.

IonQ · Oxford

Lead a team of three electronics engineers within the Systems team, acting as a player-coach with roughly 60% leadership and 40% hands-on design. Own the electronics roadmap for quantum systems, covering schematic capture, PCB layout, mixed-signal and high-speed digital design, and the transition from prototypes to rack-ready production hardware.

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.

PQShield · Remote (within the USA); Ideally Austin or California. Some travel to our offices will be required from time-to-time

Customer-facing technical role supporting sales of post-quantum cryptography software and hardware into large manufacturers, enterprises and semiconductor/security accounts. Involves requirements discovery, demos, statements of work and Q&A documentation, working closely with Sales, Engineering and Management. Open to experienced sales engineers or embedded/hardware engineers moving into sales, with 10-20% travel.

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.
