Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design, validate, and improve mechanical enclosures and subsystems for quantum products from early prototyping to industrial release. Lead thermal management and dimensional stability efforts while collaborating with multidisciplinary teams and external suppliers.
Requires a Bachelor's or Master's degree in Mechanical Engineering or Microtechnology with at least five years of relevant experience. Must have expertise in compact thermal dissipation, CAD, and industrial-grade design, with cryogenic experience being a strong asset.
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.
We are seeking a Senior Mechanical Engineer to join our R&D team in Geneva. In this hands-on role, you will design, validate, and continuously improve mechanical enclosures and subsystems that integrate optical and electronic components for our quantum products.
You will take ownership of mechanical solutions from early prototyping through to industrialized product release, with a strong focus on delivering compact, robust, and cost-effective designs. Your work will ensure compliance with dimensional, thermal, and manufacturability requirements, including for highly demanding applications such as cryogenic systems.
You will be responsible for the mechanical development of cutting-edge quantum systems, translating requirements into detailed designs and verified assemblies. This includes 3D modelling and documentation, engineering calculations and simulations, and hands-on testing to validate thermal dissipation and mechanical performance. You will collaborate closely with optical, electronic, and system engineers to optimise interfaces and block specifications, and you will engage with external suppliers to prototype and manufacture parts efficiently. As a senior contributor, you will help improve design practices, promote a rigorous engineering approach, and support multiple projects as a mechanical subject-matter expert.
We are looking for a candidate with a Bachelor’s or Master’s degree in Mechanical Engineering, Microtechnology, or equivalent, and at least five years of relevant experience in mechanical design and product development. You have hands-on experience designing with sheet metal and/or machined parts, and a strong ability to develop thermal dissipation solutions for compact systems. Familiarity with cryogenic systems is an advantage.
You are rigorous, organised, and proactive, able to work independently while collaborating effectively in a multidisciplinary and Agile environment. Strong communication skills are essential, with fluency in English required; French is considered a plus.
You bring a track record of taking ownership of mechanical subsystems across multiple development phases—requirements, design, verification, and industrialisation—and you are comfortable acting as the mechanical reference point within a multidisciplinary R&D team. Experience with compact thermal management and exposure to cryogenic constraints are strong assets.
What We Offer
· A role at one of the fastest growing and most exciting Quantum companies in the world.
· A competitive compensation scheme, benefits package and equity plan. All designed to reward excellence.
· Flexible work models that let you balance your life, your family, and your career.
· Ongoing training and development to keep your skills sharp and your growth on track.
· A career development plan within the IonQ group’s companies
· A dynamic, close-knit environment where you collaborate with a global team of experts.
· A performance-driven culture built on trust, teamwork, and shared ambition.

Global leader in quantum-safe communications and quantum detection systems
At ID Quantique, an IonQ company, we harness light to develop and industrialize advanced quantum products and technologies for organizations to ensure long-term protection of data and public safety. We believe that the ability to trust networks and communicate securely is a fundamental human right. We therefore have developed the key components of a stronger cyber security ecosystem to ensure all over the world, workers, officials, security forces but also citizens and families collaborate and exchange information safely. In a world of perpetual cybersecurity uncertainty, we have made it our mission to go beyond traditional concepts and use quantum technology to provide unfading data security assurance, today and long into a quantum computing world. We also empower researchers to create the quantum photonic building blocks of the Quantum Internet, the ultra-fast and safe communication network of the future. We strive to help them solve their most complex scientific and industrial problems with reliable and easy-to-use Swiss-made quantum optical sensing solutions. Continuous passion, a strong focus on innovation and the flexibility and experience of a dedicated team have allowed IDQ to establish itself as the leader it is today. Its products are used by governments, enterprises, industrial customers and by academic research labs in more than 60 countries and on every continent.
