Senior FPGA Architect, 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.

• 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.

• 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

• 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.

As engineering leaders, we value diversity and are committed to building a culture of inclusion to attract and engage innovative thinkers. Our technology, meant to serve all of humanity, cannot succeed if those who built it do not mirror the diversity of the communities we serve. Applications from women, minorities, and other under-represented groups are encouraged.
