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%.
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.
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.
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.
