Nanofabrication Process Technician H/F

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

YOUR (SPACE) MISSION As a Cleanroom Technician at cosine you help build the advanced optical components that will power future space missions. Working at the intersection of precision engineering and space exploration, you handle and inspect ultra-sensitive silicon components that may ultimately become part of a telescope operating hundreds of thousands of kilometres from Earth. This is a role for someone who enjoys working with their hands, takes pride in precision, and understands that exceptional quality is achieved through attention to the smallest details. Every component you touch has the potential to become part of a space instrument that will operate far beyond Earth for years to come. TASKS & RESPONSIBILITIES In this role you will: * Work extensively in a state-of-the-art cleanroom environment, handling delicate and high-value silicon components * Perform inspections and quality checks on silicon plates using standardized procedures and advanced equipment * Support the preparation, stacking and assembly of optical components for space applications * Accurately document inspection results, process data and quality findings according to established procedures * Collaborate closely with engineers, scientists and quality specialists to continuously improve processes and product quality * Take ownership of your work area and contribute to maintaining the highest cleanroom, quality and safety standards  YOUR PROFILE We are looking for candidates with the following qualifications: * MBO or HBO level education, preferably in a technical, laboratory or manufacturing-related field * A strong sense of responsibility and commitment to delivering high-quality work * Excellent attention to detail and manual dexterity for handling fragile and precision-engineered components * Curiosity and a willingness to learn and understand complex technologies and processes * Experience in a production, cleanroom, medical, pharmaceutical or other quality-driven technical environment is a strong advantage * Good communication skills in English; Dutch is considered a plus * Affinity with technology, innovation and the space sector WHAT WE OFFER At cosine, we highly value our employees, and we will support your professional and personal development. We also provide our employees with: * A unique, international working environment at the intersection of physics and engineering * A competitive salary  * 27 days of annual leave (based on full-time employment) * Annual bonus based on personal and company performance * Hybrid working options, including the possibility to work partially from home * Company bicycle and fitness plans * A personal development budget  * Initial one-year contract, with the aim of long-term collaboration ABOUT COSINE Founded in 1998, cosine is a world-leading developer of space instrumentation and measurement systems, making the invisible measurable and the complex actionable. Its expertise spans High-Energy Optics, including optics developed for ESA's future NewAthena X-ray observatory, as well as remote sensing solutions for Earth Observation and planetary science. With over 25 years of experience and advanced cleanroom and assembly facilities across the Netherlands, Germany, and Italy, cosine brings deep scientific and engineering expertise to some of the most demanding missions in space and on Earth. What makes cosine a unique place to work is that your work goes end-to-end: from concept and design to building, testing, and delivering hardware that actually flies in space. You work in small, highly skilled teams where you have real ownership and impact, alongside experts in optics, physics, nanofabrication, and systems engineering.  cosine is committed to providing an inclusive and equal opportunities work environment where everyone can thrive. As a proud member of the Women in Aerospace community, we recognise the importance of diversity, inclusion, and equal opportunity in the workplace.

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! Our Quantum Processor Team is seeking a Quantum Design Engineer to support the development of the next generation of processors. This role is focused on quantum chip design and the development of the design workflows that enable scalable processor development. You will contribute to the design and optimisation of on-chip quantum components while also helping to build and maintain the underlying design infrastructure, including PDKs, DRC flows and tapeout generation tools. Working closely with experienced designers and fabrication teams, you will play an important role in supporting the development of our large-scale QPUs. WHAT YOU’LL BE DOING * Contribute to the development of quantum chip design tools including PDKs, DRCs, tuners and tape-out generation tools. * Own quantum chip design projects for R&D and product development, contributing to the design and optimisation of new quantum processors. * Manage the full development loop for the chips you design, coordinating with fabrication and measurement teams to ensure successful transfer and execution. * Support Foundry customers in designing chips that conform to QuantWare's PDK, providing guidance throughout the design process to meet technical and operational standards. * Drive process improvement initiatives, identifying bottlenecks and recommending enhancements to tools, workflows, and design-to-tapeout processes for improved efficiency.   YOUR PROFILE Core Requirements: * MSc or higher level understanding of circuit design and microwave / RF engineering. * Hands-on experience with RF simulation tools (e.g., ANSYS HFSS, Sonnet, or equivalent), with a demonstrated ability to model and optimise microwave structures. * 4+ years of experience in collaborative Python programming. * A solid track record of delivering complex technical projects, demonstrating initiative, autonomy, and an eye for practical impact. * Strong organisational and problem-solving skills. You thrive in a cross-disciplinary environment and are comfortable taking ownership from day one.
