POSITION SUMMARY

We are seeking a Senior Embedded Systems Engineer with deep expertise in hardware-level design and embedded architecture to join our cross-functional engineering team. In this role, you will lead the design, development, and deployment of FPGA and embedded software solutions that are central to our quantum sensing systems. The ideal candidate has 10+ years of experience in embedded systems engineering, is proficient in both Verilog and VHDL, and has a strong background working with Xilinx SoMs and SoCs in Linux-based development environments.

JOB RESPONSIBILITIES

The duties and responsibilities outlined below include essential functions of the role. Depending on business needs, this role may perform a combination of some or all of the following duties. Duties, responsibilities, and activities may change, or new ones may be assigned at any time with or without notice.

+ Architect, develop, and maintain HDL code (Verilog and VHDL) for Xilinx System-on-Modules (SoMs) and Systems-on-Chip (SoCs), including Zynq, Kria, and Ultrascale+ platforms.

+ Design embedded control systems and digital interfaces, optimizing for low-latency and high-throughput performance.

+ Debug and integrate embedded systems in Linux environments, utilizing command-line tools and kernel-level interfaces where necessary.

+ Collaborate with cross-functional teams including hardware engineers, optical scientists, and software developers to deliver integrated product solutions.

+ Conduct board bring-up, hardware verification, and real-time system debugging with oscilloscopes, logic analyzers, and other lab tools.

+ Drive the development and refinement of embedded firmware/software frameworks and reusable HDL IP cores.

+ Contribute to system-level architectural decisions and participate in design reviews to ensure scalable, robust, and maintainable designs.

+ Develop automated test benches for simulation and verification of digital logic designs.

+ Experience with Git, CI/CD pipelines using Vivado (simulation, synthesis, bitstream generation), and verification frameworks like UVM or CocoTB.

+ Maintain documentation of designs, workflows, and processes in compliance with internal and regulatory standards.

Requirements

QUALIFICATIONS: EDUCATION AND EXPERIENCE

+ Bachelor’s or master’s degree in electrical engineering, Computer Engineering, or a related technical discipline.

+ Minimum of 10 years of industry experience in embedded systems and digital hardware design.

+ Proven experience developing FPGA firmware using both Verilog and VHDL.

+ Deep familiarity with Xilinx development tools (Vivado, Vitis, etc.) and Xilinx devices (Zynq SoCs, Ultrascale).

+ Strong background in developing and debugging embedded Linux environments.

+ Solid understanding of digital design principles, timing closure, and high-speed interfaces (SPI, I2C, UART, PCIe, Ethernet).

+ Demonstrated experience in architecting embedded control systems and integrating them into hardware platforms.

PREFERRED QUALIFICATIONS

+ Familiarity with real-time operating systems (RTOS) and bare-metal development.

+ Exposure to Rust or C/C++ for embedded development.

+ Experience implementing DSP algorithms using Xilinx IP blocks and HDL (VHDL/Verilog) on FPGAs for applications such as RF synthesis, filtering, or optical control is a strong plus.

+ Prior experience in regulated environments or defense/aerospace applications.

WE HIGHLY VALUE:

+ Great verbal and written communication skills to effectively share information with technical and non-technical staff

+ Strong engagement and collaboration skills with constant drive for success, ownership and pride in your work

+ Sense of urgency and responsibility and a true passion for attention to detail where it matters

+ Open communication style and extremely positive attitude which shows through consistent daily habits

+ Demonstrated problem solving skills and fast learning rate

+ Capability of working with both a high degree of autonomy (taking high level goal as an input to discover and execute an optimal plan, gathering required resources to achieve the goal) and collaboratively (soliciting and incorporating input from colleagues as necessary)
