Senior Embedded Software Engineer (PetaLinux)

TL;DR

Senior Embedded Software Engineer (PetaLinux): Building and maintaining PetaLinux-based Board Support Packages (BSPs) for AMD/Xilinx Zynq UltraScale+ MPSoC with an accent on embedded Linux bring-up, device-tree configuration, and high-rate data recording. Focus on developing user-space C++ applications for hardware control and optimizing data pipelines for radar products.

Location: Remote (US), Hybrid, or Onsite. Must be a US Citizen and be able to maintain a U.S. government personnel security clearance.

Company

Lyntris is a defense technology company that provides sensing and action solutions for U.S. and allied defense organizations across Space, Air, Land, Sea, and Cyber domains.

What you will do

• Create and maintain PetaLinux projects and BSPs, including platform bring-up, image generation, and rootfs customization.
• Author and maintain device tree changes for custom IP/peripherals and debug Linux subsystem integration.
• Develop C++ user-space applications for hardware control, UDP streaming, and high-rate radar data recording to SSD.
• Implement and modify low-level board support and Linux device drivers for custom data paths.
