Senior Engineer Analog Design for Cryogenic Trapped Ion Quantum Computing (f/m/div)

Senior Engineer Analog Design for Cryogenic Trapped Ion Quantum Computing (f/m/div)

Join to apply for the Senior Engineer Analog Design for Cryogenic Trapped Ion Quantum Computing (f/m/div) role at Infineon Technologies

Responsibilities

• Define and evaluate analog control architectures for scalable trapped ion systems, balancing speed, power, noise, and scalability requirements with your deep understanding of trapped ion quantum computing
• Design cryogenic high voltage (HV) switching matrices suitable for use at cryogenic temperatures
• Architect and realize a high-speed, low-power analog front‑end and digital interface to enable reliable communication between a room-temperature controller and the cryogenic switching matrix
• Perform detailed circuit simulation (including low‑temperature device models), layout, and verification; collaborate with layout engineers to ensure robust HV and noise performance
• Drive system‑level trade‑offs and roadmaps for scalable electrode control, including reliability, thermal load minimization, and EMI considerations
• Mentor and lead junior engineers, prepare technical reports and contribute to publications/presentations
• Enable scalable trapped ion quantum computing

Qualifications

• MSc in Electrical Engineering, or a comparable degree with a strong focus on cryogenic analog/mixed signal circuit design
• Substantial, hands‑on experience in cryogenic high voltage analog design
• In‑depth knowledge of cryogenic electronic device behavior and expertise in low temperature modeling
• Direct experience with trapped ion experiments or active involvement in trapped ion control systems
• Proficiency with circuit design and verification tools (e.g., Cadence or similar), including simulation of noise, device models, and power integrity
• Strong experience in prototype validation and cryogenic measurement techniques (cryostat testing, low noise measurements, thermal management)
• Excellent written and verbal English skills and German is a plus
• Strong collaboration and communication skills, ability to interface with physicists, system engineers, and fabrication partners
