Job Description

As a direct report to the CEO, you will play a critical role in building a resilient and scalable engineering organisation. You will leverage our R&D teams as they address the core scientific and technical challenges of developing a utility-scale, fault-tolerant quantum computer. You will be responsible for defining and documenting how we conceive, design, and build our final, long-term quantum computer - a large-scale quantum processing unit (QPU) consisting of hundreds of thousands of high-quality, highly connected physical qubits and incorporating quantum error correction. In our job description, this is referred to as "the system." You will introduce tools and practices that foster a high-performance engineering culture and work closely with our multidisciplinary team of engineers and physicists to bridge the gap between system architecture and practical implementation. Additionally, you will develop our near-term quantum production line, designing and optimising manufacturing process flows to support the production of future QPU products. Our product roadmap is structured around a clear set of engineering requirements for each generation of product. You will also establish advanced measurement and testing facilities essential for hardware validation and long-term reliability. This role will eventually include team management responsibilities.

Job Responsibility

  • Systems engineering: Guiding “the system” through its entire lifecycle - from initial conceptualisation and design through detailed development and rigorous validation
  • Collaborate with product, design & R&D teams to define, refine, and document system requirements that align with technical and business goals
  • Maintaining a system-level perspective, integrating cross-functional & external inputs and identifying technological barriers to industrialisation
  • Acting as a communication hub for technical decision-making and documentation, ensuring that the R&D knowledge is captured, understood, and applied throughout development
  • Defining and documenting validation test plans of components/sub-systems/systems to verify that each of them meets its specifications and performance targets
  • Collaborating with partnerships and supply teams to support informed make-or-buy decisions
  • Manufacturing & advance testing facilities: Designing, developing, and deploying a new quantum production line optimised for carbon nanotube-based quantum chips, building on processes developed by the R&D teams
  • to establish a stable, scalable process that enables high-throughput production.
  • Overseeing the conception, construction, and commissioning of advanced measurement and testing facilities
  • Collaborating with research and product teams to translate prototypes into scalable and manufacturable designs
  • Engineering excellence: Implementing best practices in project management, design control, and quality assurance across all engineering activities
  • Communicating engineering plans, progress, and risks to executive leadership and key stakeholders
  • Introducing “Design for Manufacturability” strategies for new products and drive process standardisation initiatives to facilitate production scale up

Requirements

  • Master’s degree and/or Ph.D. in physics, engineering or a related technical field
  • 10+ years of engineering leadership experience in high-tech industries such as semiconductors, advanced instrumentation, or quantum technologies
  • Proven experience in systems engineering of highly complex, large-scale technologies (e.g.quantum computers, spacecraft, aircraft, or multidisciplinary hardware systems)
  • Familiarity with Model Based Systems Engineering (MBSE), experience with an MBSE software platform and knowledge of system modelling, simulations, and analysis tools
  • Knowledge of quantum devices, cryogenic systems and RF/microwave systems or precision measurement tools (experience in at least one is required)
  • Thorough understanding of semiconductor design, integration & process modules including e-beam lithography, dry etch, wet etch, chemical vapour deposition (CVD), sputtering, and atomic layer deposition (ALD)
  • Experience leading multi-disciplinary teams and integrating mechanical, electrical, and software systems
  • Strong verbal and written communication skills
  • Fluency in English is mandatory, fluency in French is preferred

Nice to have

  • You like hands-on work and technology
  • You want to contribute to achieving landmark results in quantum computing, making a difference in the emerging quantum technologies
  • You want to work within a 60-people team with various backgrounds in nanofabrication, quantum electronics, and carbon nanotube science to create a revolutionary quantum computing processor
  • You want to thrive in an exceptional scientific environment with several industrial and academic partners
  • You share our values (excellence, scientific integrity, diversity, curiosity, and care) and want to help us define our product-focused culture and ambition to accelerate.
