Job Description

Responsibilities

• Develop and improve a custom microprocessor responsible for waveform generation and critical logic to operate a quantum computer
• Work closely with hardware, firmware, and software teams to define architecture, data flow, and interfaces.
• Implement, simulate, and verify designs including DSP pipelines, control logic, and high-speed I/O.
• Optimize designs for latency, resource utilization, and robustness in production environments.
• Develop and maintain testbenches, verification flows, and CI.
• Support bring-up, lab validation, and debugging in collaboration with Quantum Engineering on actual quantum computers.
• Contribute to the long-term roadmap for the architecture of Rigetti’s control systems.

Requirements

• Bachelor's degree or higher in Electrical Engineering, Computer Engineering, or related field, or equivalent practical experience.
• 7+ years of experience in FPGA design and development for complex mixed signal systems.
• Experience architecting a new design from the ground-up
• Proficiency in Verilog and/or VHDL, along with experience using an industry-standard FPGA toolchain (Xilinx, Intel/Altera, or similar).
• Strong understanding of at least one of processor architecture design (memory bandwidth, caches, instruction decoding latency, etc.) and/or digital signal processing (filter design and implementation, IIR, FIR, FFT, polyphase filters, multi-rate systems).
• Experience with high-speed serial interfaces (e.g., PCIe, JESD, SERDES).
• Solid understanding of digital design fundamentals: timing closure, CDC, reset strategies, resource utilization, and verification.
• Experience collaborating on cross-functional teams

Preferred Qualifications

• Experience with RF/microwave or mixed-signal systems
• Familiarity with ASIC design
• Experience with real-time control systems, data acquisition, or instrumentation.
• Exposure to quantum computing, test and measurement equipment, and the scientific python stack.
