FPGA & Firmware Engineer at Sateliot – Barcelona | Jobyssey

WHO ARE WE?

Sateliot is a Barcelona-based Startup in the New Space sector, becoming the first satellite telecommunications operator that will provide global and continuous connectivity to all the elements that will make up the massive Internet of Things (IoT) universe under the 5G protocol.

In order to do so, Sateliot is launching a constellation of last generation nanosatellites, located at low altitude that act as mobile towers. Sateliot is the perfect complement for large telecommunications companies by providing them with the necessary infrastructure where terrestrial technologies do not arrive.

YOUR MISSION

Working within the Payload team, your mission is to develop the "brain" of our satellites end-to-end — from FPGA logic to embedded firmware running on the SoC. Your role is a dynamic 50/50 mix of FPGA design (RTL) and embedded firmware (PS) on the same target. You will be the bridge between hardware logic and the software running on top of it.

YOUR MAIN FUNCTIONS

•RTL Design & Integration: Design and implement digital logic in SystemVerilog or VHDL on the PL side. Integrate IP blocks and bridge them via AXI4 / AXI4-Stream / AXI4-Lite.

•Embedded Firmware: Write C / C++ firmware running on the SoC's processing system — drivers, control logic, data path, and hardware-software interaction.

•Embedded Linux: Build and configure the embedded Linux image with PetaLinux and/or Yocto — kernel configuration, device tree, drivers, and rootfs customization.

•High-Speed Interfaces: Bring up and validate high-speed PL interfaces between FPGA and external devices.

•Automation & Scripting: Develop and maintain scripts in Python and Tcl to automate build processes, testing workflows, and lab verifications.

•Hands-on Debugging: Work in the lab with real hardware to debug signals, validate payload performance, and troubleshoot integration issues.

REQUIREMENTS

Education & Experience

•Bachelor's or Master's degree in Electrical Engineering, Telecommunications, Computer Engineering, or a related field.

•2 to 4 years of professional experience covering both FPGA RTL design and embedded firmware on the same SoC platform — Xilinx/AMD Zynq/Versal or Altera/Intel SoC FPGA are both welcome.

Technical Skills

•Strong SystemVerilog or VHDL on the PL side.

•Strong C / C++ for embedded systems (pointers, memory management, low-level drivers).

•Embedded Linux on ARM — kernel modules, device tree, drivers; or strong baremetal background and willingness to ramp into Linux.

•PetaLinux and/or Yocto build-flow experience.

•AXI protocol family on the PL side (AXI4 / AXI4-Stream / AXI4-Lite).

•High-speed interface integration.

•Comfortable working in a Linux environment and using the command line (Bash), and with Git version control workflows.

•Demonstrable ability to write scripts in Python or Tcl for automation tasks.

•AI-Augmented Engineering: experience using AI coding assistants (e.g., Cursor AI, Copilot, Claude) to accelerate development and debugging, or a strong willingness to adopt these tools to work smarter and faster.

•Professional proficiency in English.

Soft Skills

•A proactive attitude and a genuine passion for Space Tech and 5G.

•Strong problem-solving skills and the ability to work independently when needed.

•Eagerness to learn and share knowledge with the team.

NICE TO HAVE

•Versal know-how is a plus (newcomers will go through our internal Versal training course and reference material).

•AI Engines (AIE / AIE-ML) or Vitis HLS exposure.

•Previous exposure to Xilinx tools like Vivado or Vitis (or Altera/Intel Quartus equivalents).

•Basic knowledge of Software-Defined Radio (SDR) or baseband processing concepts.

•Specific interest in satellite payloads, 5G NTN, or space-grade design.
