Staff System Arcitect

Genève, Geneva, Switzerland

ID Quantique (IDQ) as part of IONQ, is a global leader in quantum-safe communications and quantum detection systems. We provide solutions to protect governments, telecommunication infrastructures, and banking & financial institutions from the “harvest-now, decrypt-later” threat, delivering both terrestrial and space-based quantum-safe networks in live operation globally. Our Quantum Detection Systems push the limits of single-photon detection, powering breakthroughs in quantum communication, sensing, computing, and ultra-sensitive imaging in partnership with top researchers and tech innovators worldwide.

What to expect

We are looking for a Staff System Architect to be fully dedicated to the SNSPD product line, with a strong focus on leading the technical architecture and roadmap for our next-generation rack-mountable SNSPD (Superconducting Nanowire Single-Photon Detector) platform. This role is critical to defining and guiding the technical evolution of our cutting-edge cryogenic photon detection systems, ensuring architectural coherence across hardware, software, and integration domains while supporting our product vision and market requirements.

What you'll be doing

In this role, you will be an integral part of the development process for IDQ’s SNSPD platform, with applications across quantum computing, networking, and sensing. You will be at the intersection of quantum photonics, cryogenic systems engineering and embedded systems to create scalable, maintainable architectures for autonomous 24/7 detector operations. 

You will take ownership of the end-to-end system architecture of the SNSPD platform, ensuring alignment with a shared long-term product vision while translating product requirements into clear system-level designs and specifications. This includes defining system structure, interfaces, and key architectural decisions, as well as driving critical trade-offs across performance, cost, scalability, and integration. You will also align engineering execution with the architectural vision, guiding system integration and resolving complex cross-domain design challenges.

In addition, you will play a key role in shaping the technology roadmap and driving the evolution of the platform, continuously evaluating and introducing new technologies where relevant to maintain innovation and competitiveness.

  • Lead system architecture, design decisions, and cross-functional alignment to ensure a scalable and high-performing SNSPD platform
  • Drive technology roadmap, integration, and innovation by evaluating and implementing new technologies

What you'll bring

We are seeking a highly experienced professional with a Master’s degree in physics, electrical engineering, photonics, or a related field, and over seven years of experience in system architecture or complex system design. The ideal candidate will bring expertise in multi-domain systems, including photonics, cryogenics, electronics, and embedded or software components, combined with strong system-level thinking and proven experience in integrating complex technologies into cohesive, high-performing solutions.

You will demonstrate strong technical leadership across multidisciplinary teams, with the ability to clearly communicate complex system architectures to a wide range of stakeholders. This includes ensuring alignment, supporting informed decision-making, and driving successful collaboration across functions to deliver robust and scalable system designs.

  • Extensive experience in system architecture and multi-domain integration, with strong system-level thinking
  • Proven technical leadership and communication skills, enabling alignment and effective decision-making across diverse teams

You'll be a great fit with

  • PhD in a relevant field
  • 10+ years in senior technical or architectural roles
  • Experience with SNSPDs, cryogenic, or quantum systems
  • Experience with industrialized or rack-mountable systems
