Mid-Level Fpga Engineer

Xona is building the next generation of satellite navigation a high-performance, resilient alternative to GPS powered by a commercial constellation of low Earth orbit (LEO) satellites. We are on a mission to unlock a new era of autonomy, advanced mobility, and infrastructure resilience by delivering precise, secure, and robust positioning services to the world.

We're not here to incrementally improve GNSS. We're here to redefine it from the ground up.

We are seeking a mid-level FPGA engineer to join our team working on high-reliability digital systems for space-based navigation payloads. In this role, you'll contribute to the design, implementation, and testing of FPGA logic for real-time, mission-critical applications. You'll work closely with hardware and systems teams to help bring our next-generation payloads from concept to flight.

What you'll do :

Develop, implement, and verify RTL designs for Xilinx FPGAs (e.g., RFSoC, Zynq Ultrascale+)
Build and maintain digital processing pipelines, control logic, and data interfaces
Support hardware bring-up and system integration on custom satellite payloads
Design for fault tolerance and space reliability, including SEU mitigation and system monitoring
Collaborate with systems, hardware, and software engineers to define and validate FPGA requirements
Participate in lab testing, simulation, and design reviews
Document designs, test plans, and development processes in a structured, reviewable format

Requirements :

Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field

35 years of professional FPGA design experience using Verilog, VHDL, or SystemVerilog

Strong experience with FPGA development flows, including Vivado or similar tools

Proficiency in simulation, verification, and hardware debugging techniques

Familiarity with on-chip interfaces such as AXI, AXI-Stream, and clock domain crossing

Hands-on experience bringing up FPGA designs in a lab environment

Comfortable working in a Linux development environment with version control tools like Git

Must be able to work full-time onsite in Burlingame, California

Desired qualifications :

Experience working with Xilinx Zynq or RFSoC devices

Exposure to space system development, including SEU mitigation techniques and fault-tolerant design

Familiarity with high-speed interfaces, memory controllers, or custom peripheral integration

Scripting experience (e.g., Python or TCL) for automating test and build processes

Experience collaborating on multi-disciplinary hardware / software projects

Understanding of space qualification and hardware validation processes is a plus
