About the role

Develop new FPGA designs for integration into electronic modules to control and operate photonic quantum computers
Implement control and feedback loops within FPGAs interfacing with peripherals (ADCs, DACs, SPI, I2C, etc.)
Work on phase stabilization of optical fiber connections, control of electro-optic modulators, optical homodyne measurements, photon-number resolving detectors, and laser pulse sequencing
Communicate with other FPGAs and servers using various communications protocols
Work closely with physicists, engineers, and technicians to integrate electronic modules into quantum computer systems
Provide support to teams using these modules: debugging issues and implementing new features to increase functionality and usability
Participate in schematic review meetings and obtain FPGA design requirements from schematics, datasheets, and work instructions

3+ years experience writing RTL (Verilog or VHDL, SystemVerilog preferred)
Experience developing FPGA designs interfacing with peripheral devices (SPI, I2C, etc.)
Experience bringing up an FPGA design from scratch, starting from the schematic
Strong experience in reading and understanding electrical schematics, technical drawings, datasheets, and written work instructions
Experience with validation and verification of designs
Experience writing simulation testbenches
Familiarity with Vivado or Quartus (Vivado preferred)
Some experience with Python and TCL
Knowledge of general data communication interfaces and protocols (SPI, I2C, JTAG, PCIe, UART, USB, TCP/IP, etc.)
Experience with clocking architecture, timing constraints, low jitter applications
Familiar with control systems design/theory (PID loops, feedback theory)
Experience with bitstream/firmware/bootloader deployment strategies
Experience with electronic test and measurement equipment (oscilloscope, JTAG debugging (ILA/VIO))
Background in hands-on debug and verification experience in a lab environment
Proficiency in analog and digital circuits design (op-amp, ADC/DAC, power management, FPGA, SRAM/DDR, etc.)
Experience with Xilinx FPGAs (Series 7, Ultrascale+) an advantage
Familiarity with source control, particularly git
Experience with writing C/C++ code for embedded microcontrollers
Familiarity with photonics and optical physics
