The Role:
We are looking for a Senior Microwave Research Scientist. As a Senior Microwave Research Scientist, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems.
In this role, you will architect and refine cutting-edge microwave circuits for the electronic control of high-fidelity spin qubits. You’ll spearhead the integration of these circuits with advanced optical and electronic devices to push the boundaries of system-level performance. Your leadership will drive the end-to-end cycle from foundry fabrication to rigorous internal validation, ensuring world-class performance for our quantum hardware.
Responsibilities:
- Collaborate with architecture teams to translate system-level specifications into component-level design rules and performance metrics
- Design microwave circuits for electronic control of qubits, accounting for fabrication constraints, cryogenic compatibility, and system-level interactions
- Manage the end-to-end design layout and mask handoff process, partnering with foundries to fabricate devices at scale
- Lead internal validation efforts with test and measurement teams to ensure fabricated components meet target performance specifications
Requirements:
- 10 + years of experience designing microwave devices
- MS in electrical engineering, physics, or a related field
- Experience leading cross-disciplinary teams within large projects
Preferred Qualifications:
- PhD in electrical engineering, physics or related field with 5+ years of experience
- Experience hiring and training new teams for research and development work
- Knowledge of cryogenic testing and operation
- Familiarity with architectures for distributed quantum computing, sensing, and networking
