IonQ is developing the world's most powerful full-stack quantum computer based on trapped-ion technology to unlock a new era of computing and redefine industries such as medicine, materials science, finance, artificial intelligence, machine learning, and cryptography. The Staff Quantum Control Hardware Engineer will contribute to building the physical layer interface for next-generation quantum networking nodes and high-precision sensing devices.
Requirements
- Bachelor’s or Master’s degree in Electrical Engineering, Physics, or a related engineering discipline.
- 8+ years of experience (or equivalent) in mixed-signal hardware design and PCB layout.
- Deep expertise in designing low-noise analog circuits and high-precision instrumentation.
- Proven experience with high-speed ADCs/DACs and signal conditioning chains.
- Proficiency with EDA tools for schematic capture and PCB layout (e.g., Altium, Cadence).
- Strong understanding of signal integrity, power integrity, and grounding in sensitive measurement systems.
- Experience designing hardware for low-latency networks, optical communications, or quantum communications.
Responsibilities
- Design and develop low-noise, high-precision mixed-signal circuit boards (DACs/ADCs) to drive optical modulators and laser sources for quantum networking protocols.
- Engineer ultra-low-noise readout interfaces for single-photon detectors used in Quantum Key Distribution (QKD) and sensing applications.
- Ensure hardware designs maintain the signal integrity and coherence required to preserve quantum states during transmission and transduction.
- Collaborate closely with FPGA Engineers to receive timing specifications and deliver signal conditioning specs for synchronization across network nodes.
- Lead the full hardware lifecycle from schematic capture and PCB layout to simulation, testing, and system integration within a sensing or security testbed.
- Troubleshoot complex hardware interactions to minimize phase noise and jitter in networking hardware.
- Mentor junior hardware engineers and drive technical decision-making regarding the physical layer architecture for security products.
Other
- This role will work onsite at our offices located in Bothell, WA or Vista, CA.
- Travel up to 10%.
- Must be a U.S. Person (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) for export controls and government contracts work.
- Additional questions regarding immigration status will be used for export control and compliance purposes.
