Qualifications

Responsibilities:Develop, implement, and verify VHDL/Verilog firmware for Field-Programmable Gate Arrays (FPGAs) with a focus on the real-time classical control channel. Implement nanosecond-level synchronization protocols (e.g., White Rabbit-PTP) to ensure 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 vital for quantum operations. Define and provide the hardware abstraction layer (registers, interrupts, and memory-mapped controls) utilized by higher-level QNodeOS developers. Collaborate closely with Hardware Engineers to comprehend board timing constraints, signal paths, and low-level control requirements. Own the complete FPGA development lifecycle from specification and RTL design to testing, timing closure, and system integration. Drive technical decisions regarding timing architectures and control strategies for the real-time embedded system.
