• Integrate subsystems into quantum systems, including verification and debugging.


• Ensure high test coverage using CI pipelines and hardware test beds.


• Develop programmable logic and low-level CPU interfaces for integrated systems.


• Create test scripts for subsystem validation.


• Support board bring-up and debugging efforts, providing feedback to design teams.


• Collaborate with electrical, mechanical, software, and physics teams for system integration.


• Enhance system usability and reliability for applications and demo teams.


• Operate and interface with electrical and optical lab test equipment.


• Work with Rust firmware engineers to define architecture and drivers.

Qualifications:

• BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or related field.


• 4+ years of experience in embedded systems, FPGA development, or mixed signal design.


• Familiarity with embedded system development in Rust or C/C++, and FPGA development in HDL with RF synthesis experience.


• Experience interfacing with hardware (SPI, I2C, UART, Ethernet, etc.).


• Strong debugging skills across hardware and software boundaries.


• Experience with common benchtop test equipment.

Skills:

• Experience with RF systems, signal generation, or data acquisition hardware.


• Familiarity with control systems or feedback loops.


• Experience with FPGA-based systems.


• Experience developing test or automation frameworks.


• Exposure to scientific instrumentation or R&D environments.


• Exposure to hardware design and schematic capture.
