Team: Control Systems
Rigetti is seeking a Senior FPGA Architect to join the development of FPGA-based control hardware used to drive our quantum processors. In this role, you will define FPGA architectures, implement high-performance digital logic, and collaborate closely with hardware, firmware, and quantum engineering teams to build scalable, low-latency control systems.
Responsibilities
Develop and improve a custom microprocessor responsible for waveform generation and critical logic to operate a quantum computerWork 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-upProficiency 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 teamsPreferred Qualifications
Experience with RF/microwave or mixed-signal systemsFamiliarity with ASIC designExperience with real-time control systems, data acquisition, or instrumentation.Exposure to quantum computing, test and measurement equipment, and the scientific python stack.
