Senior Real-Time Embedded Systems Engineer

IonQ is developing the world's most powerful full-stack quantum computer based on trapped-ion technology. We are looking for a Senior Real-Time Embedded Systems Engineer to join our team. As a Senior Engineer, 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 and networked systems to solve the world’s most complex problems.

Requirements

• Develop, implement, and verify VHDL/Verilog firmware for Field-Programmable Gate Arrays (FPGAs) focusing on the real-time classical control channel.
• Implement nanosecond-level synchronization protocols (e.g., White Rabbit-PTP) to maintain sub-nanosecond precision across distributed hardware systems.
• Design and optimize hardware triggers for immediate photon generation and detection events.
• Engineer the logic necessary for high-speed, low-latency “Repeat-Until-Success” feedback loops critical for quantum operations.
• Define and provide the hardware abstraction layer (registers, interrupts, and memory-mapped controls) consumed by the higher-level QNodeOS developers.

Benefits

• Comprehensive medical, dental, and vision plans
• Matching 401K
• Unlimited PTO and paid holidays
• Parental/adoption leave
• Legal insurance
