Quantum Hardware Engineer

• Take ownership of a key subsystem of our quantum computer (e.g. building optical subsystems, laser distribution, operating the quantum processor)
• Design, build, and optimize high-performance experimental setups for neutral atom quantum systems
• Integrate your subsystem into the full quantum computing stack and ensure reliable system operation
• Collaborate closely with software, mechanical, and electrical engineering teams to enable seamless system performance
• Drive iterative improvements in system stability, scalability, and performance
• Contribute to system architecture decisions and technical roadmap discussions

• PhD or Postdoc in AMO physics or a closely related field

• Strong hands-on experience with lasers, optical setups, and experimental quantum systems

• Proven experience in building and operating complex experimental setups

• Background in one or more of the following areas:

• Optical tweezer arrays / atom arrays

• Rydberg atoms or alkaline-earth atoms

• Ultracold atoms, trapped ions, or UHV systems

• High-NA imaging and addressing systems

• Frequency- and amplitude-stable laser systems

planni ist ein spezialisiertes SaaS-System, das auf die spezifischen Anforderungen von Seminar- und Weiterbildungsanbietern zugeschnitten ist. Unsere Vision geht jedoch weit darüber hinaus: Wir entwickeln planni zu einem AI-basierten ERP für mittelständische Dienstleister. Wir bieten eine umfassende Lösung für die Verwaltung von Teilnehmern, Buchungen, Rechnungsstellung und komplexen Workflows – vom ersten Kontakt bis zur Nachbereitung eines Seminars, vollständig digital abgebildet. Unser Produkt wächst rasant und erfordert nun die Verstärkung unseres Entwicklungsteams, insbesondere in der Feature-Vertiefung und der Integration zukunftsweisender Technologien.
