Senior Embedded Systems Engineer

Job Title

Senior Embedded Systems Engineer

Role Summary

Develop and integrate embedded hardware, firmware, and gateware for Quantum RF (QRF) sensing systems. Work on control system architectures, board bring-up, verification, and lab-to-field system integration.

Collaborate with electrical, mechanical, software, and physics teams to deliver reliable, testable systems and support application and demo teams.

Experience Level

Senior — typically requires 4+ years of relevant experience in embedded systems, FPGA development, or mixed-signal design.

Responsibilities

Key responsibilities include system design, integration, testing, and cross-functional collaboration.

• Design, develop, and maintain embedded software and gateware for QRF systems.
• Define and implement control system architectures for quantum sensors.
• Integrate and verify subsystems; perform debugging across hardware and software boundaries.
• Develop programmable logic and low-level CPU interfaces for integrated systems.
• Create and run test scripts; maintain CI pipelines and hardware testbeds to ensure high test coverage.
• Support board bring-up, lab testing, and provide feedback to design teams.
• Operate and interface with electrical and optical lab test equipment.
• Collaborate with firmware engineers (including Rust) to define architecture and drivers.

Requirements

Must-have technical skills and experience. Nice-to-have items listed separately.

• Must-have: 4+ years in embedded systems, FPGA development, or mixed-signal design.
• Must-have: Proficiency in low-level embedded development in Rust or C/C++ and FPGA development in HDL.
• Must-have: Experience with hardware interfaces (SPI, I2C, UART, Ethernet) and strong cross-boundary debugging skills.
• Must-have: Experience using benchtop test equipment and developing test or automation frameworks.
• Nice-to-have: RF systems, signal generation, or data acquisition hardware experience.
• Nice-to-have: Experience with control systems/feedback loops, scientific instrumentation, and hardware schematic capture.

Education Requirements

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