Nanofabrication back end technician F/H

Alice & Bob

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems. The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈‍⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!   We're a diverse team of 180+ brilliant minds from over 30 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!   Alice&Bob développe un ordinateur quantique basé sur des qubits chats🐈‍⬛. Après avoir initialement réalisé la nanofabrication des circuits dans des salles blanches académiques, Alice&Bob passe à la vitesse supérieure en exploitant sa propre salle blanche de prototypage en Île-de-France. Au sein du département Quantum Hardware, l’équipe « nanofabrication backend » joue un rôle central dans le process de fabrication des processeurs quantiques d’Alice&Bob.  L’équipe est responsable de : La livraison régulière de puces de test Le développement et l’amélioration des procédés (qualité, sélection de puces…) La gestion des équipements : vérifications quotidiennes, suivi du planning de maintenance, premier niveau de dépannage La sélection, l’installation et la qualification de nouveaux équipements  

QuantWare

ABOUT US QuantWare is building the world’s most powerful quantum processors to solve humanity's greatest challenges. We do this with our unique VIO™ technology, the only QPU architecture that breaks the hardware barriers that have held quantum computing back, unlocking the path to MegaQubit quantum processors. With VIO, we are paving the way for the hyper-scale quantum computers that will change the world. And delivering on that vision demands people who don’t shy away from tackling the hardest challenges of our time. That’s where you come in! As a Fabrication Engineer for Parametric Quantum Devices, your work will be essential to advancing the performance and scalability of our quantum processors. You will focus on the research, development, and physical realization of the quantum signal chain, with a particular emphasis on Traveling Wave Parametric Amplifiers (TWPAs) and readout components—utilizing superconducting devices both with and without Josephson junctions. You will work in an international, collaborative environment, bridging the gap between fundamental physics and engineering. Working in a tight feedback loop with experimentalists and design engineers, you’ll turn measurement insights into rapid fabrication iterations that push the performance of our parametric devices. Your contributions will be essential in meeting our technical and product milestones, ensuring QuantWare remains at the forefront of quantum computing innovation. What you'll be doing * Fabrication Workflow Optimization: Continuously improve our fabrication workflow for readout devices and TWPAs, utilizing feedback from the measurement and design engineers to iterate on device performance. * Process Standardization: Develop and maintain high-standard protocols for the fabrication of superconducting components, ensuring high yield and reproducibility across different wafers. * Innovative Material Research: Investigate new materials and technological solutions to improve device metrics. * Documentation & Reporting: Maintain detailed documentation of experimental setups, process protocols, and characterization results; prepare technical reports and presentations to communicate progress and insights to the wider team. * Collaborative Development: Work closely with multidisciplinary teams to ensure that innovations in the readout chain are successfully integrated into our next-generation quantum processors. Your Profile * Nanofabrication and cleanroom experience with E-beam / UV lithography / dry etching / wet etching / PVD and CVD/ diagnostics (2+ yrs). Specialized experience in Josephson junction fabrication is highly valued. * A Ph.D. or equivalent experience (Master’s degree + 2 years of industry experience) in Physics, Materials Science, Electrical Engineering, or a related field. * Hands-on experience in a cleanroom environment, fabricating superconducting devices. * Ability to work effectively both independently and as part of a multidisciplinary team. * Excellent written and verbal communication skills. Don't tick every box? Apply anyway. We know great candidates don't always follow a straight path, and we value diverse experience, perspectives, and ways of thinking. If this role excites you and you believe you can make an impact, we'd love to hear from you! What We Offer: At QuantWare, you’ll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you’ll have the trust, tools, and support to do your best work. Here’s what you can expect: Competitive salary - A salary that reflects the impact and importance of the role (and of course 8% holiday allowance) Pension that’s built to last - A generous and future-proof pension plan that includes partner and dependent coverage. Flexibility built on trust - We focus on outcomes. Work flexibly, in a hybrid setup, with an open vacation policy that lets you manage your time Personal growth - We invest in your L&D, with a budget available to each team member, dependent on their individual ambitions, development needs, and performance A connected team - We make space to celebrate wins together, with team events, offsites, and spontaneous moments that bring us closer Diversity & Inclusion at QuantWare We’re an ambitious company, not only for our goals but also to become an even more diverse and inclusive team. We know this helps us with better decisions, more innovation, and strengthens our culture. In particular, we’d love to see more women in the quantum industry! So if you’re a female talent, excited about this opportunity but don’t meet every single requirement, we still encourage you to apply. As part of our recruitment process, candidates may be required to undergo pre-employment screening.
