Senior Embedded Software Engineer

Lyntris is a defense technology company that connects sensing to action across the connected battlespace. Lyntris brings together the talents of Accelint and Vitesse teams under one mission, with each contributing deep expertise within their domain. Combining differentiated hardware, software and mission expertise, Lyntris helps customers sense threats, make sense of complex conditions and act with greater speed, precision and confidence in contested environments.

Lyntris supports U.S. and allied defense organizations across every branch - including Navy, Army, Air Force, Space Force and allied partners - spanning strategic, operational and tactical missions and every domain: Space, Air, Land, Sea and Cyber. With more than 200 active defense programs, Lyntris works at every level of the mission, from national command authority to the tactical edge.

Solutions are designed by operators who understand the mission, engineered for the conditions that degrade or defeat standard systems, and built on an open, modular architecture that integrates into existing programs without requiring them to start over. Lyntris moves faster than the traditional defense cycle - with integrated design, build and test capabilities in-house - and delivers systems that sustain and endure long after initial fielding.

• Senior Embedded Software Engineer (AMD MPSoC/PetaLinux)
• Full Time
• Remote

We are seeking an Embedded PetaLinux Software Engineer to build and maintain PetaLinux-based Board Support Packages (BSPs) for the AMD/Xilinx Zynq UltraScale+ MPSoC (initially on ZCU102, evolving to custom hardware). The role includes embedded Linux bring-up, device-tree + kernel configuration, and development of user-space applications to control FPGA-attached hardware, stream high-rate data, and record radar data to a PC for analysis and visualization.

You'll work closely with FPGA, and systems teams to integrate drivers, validate peripherals, and build reliable data pipelines for development and test.

• Create and maintain PetaLinux projects and BSPs: platform bring-up, image generation, kernel configuration, rootfs customization, and packaging.
• Integrate hardware handoff artifacts (e.g., XSC), configure boot chain, and support Linux boot on Zynq UltraScale+ MPSoC platforms.
• Author/maintain device tree changes for custom IP/peripherals; debug peripheral enumeration and Linux subsystem integration.
• Maintain reproducible builds (Yocto/PetaLinux layers, versioning, build docs, CI hooks as appropriate).

• Support board bring-up and peripheral checkout (GPIO, SPI, UART, Ethernet, DMA, etc.), troubleshooting boot/performance issues.
• Implement/modify low-level board support and (as needed) Linux device drivers for custom data paths and control interfaces.

• Develop user-space applications (C++) to:
• • Configure/control hardware (register access, SPI/UART devices, GPIO, timing, sensors)
  • Stream data from the MPSoC to a PC (UDP) for visualization and recording
  • Record high-rate radar products (I/Q maps, metadata) reliably to SSD with indexing and replay support
• Build and maintain host-side tools (Windows or Linux) for capture, verification, file conversion, and integration with downstream processing/UI.

• Create test utilities and automated validation (unit-tests, bring-up scripts, throughput tests, etc.).
• Profile and optimize throughput and CPU usage (zero-copy paths where possible, DMA + buffer management, network tuning).
• Collaborate across FPGA/EE/SW to diagnose integration issues and propose architecture improvements.
• Performs other duties as assigned.

• BS in EE/CE/CS (or equivalent experience)
• 5+ years of trong embedded Linux experience on SoCs (boot, BSPs, kernel/rootfs, device tree)
• Hands-on experience with PetaLinux and/or Yocto-based BSP workflows for Zynq UltraScale+ MPSoC class devices
• Solid C/C++ proficiency (or strong Python with systems-level comfort); ability to debug across user/kernel boundaries
• Experience with Linux networking and high-throughput data movement (socket programming, buffering, backpressure, performance tuning)
• Comfortable with lab bring-up: serial consoles, JTAG/debug, logs, packet capture, and hardware/software co-debug

• Direct experience with ZCU102 (or similar Zynq UltraScale+ dev boards) and FPGA+Linux integration
• Experience developing/maintaining Linux drivers, DMA interfaces, or high-rate acquisition pipelines
• Familiarity with AMD/Xilinx embedded software ecosystem (e.g., Vitis, PetaLinux tooling, Yocto)
• Experience with data recording formats for large binary products (chunked files, circular buffers, memory-mapped I/O, etc.)
• Familiarity with containerized build environments, CI/CD for embedded builds, and release/version management
• Nice-to-have: radar/DSP domain familiarity (I/Q data, FFT maps, GPS synchronization)

• Target: AMD/Xilinx Zynq UltraScale+ MPSoC on ZCU102, evolving to custom boards
• OS/Build: PetaLinux / Yocto-based embedded Linux
• Languages: C/C++, Python, Svelte, Javascript
• Host: Windows and/or Linux tooling for capture, control, and analysis

• Bootable, versioned PetaLinux image with documented build + bring-up procedure
• Stable device-tree/kernel configuration for required peripherals
• Control application/API that configures hardware deterministically
• Sustained, verified data streaming and PC SSD recording for radar products with integrity checks and replay tools
• Automated throughput and regression tests

This position offers flexible work arrangements, including fully on-site, hybrid, or remote options. Proximity to the Panama City, FL location is preferred for hybrid candidates.
