Note: The job is a remote job and is open to candidates in USA. Accelint is a defense technology company that connects sensing to action across the connected battlespace. They are seeking a Senior Embedded Software Engineer to build and maintain PetaLinux-based Board Support Packages for the AMD/Xilinx Zynq UltraScale+ MPSoC, focusing on embedded Linux bring-up and user-space application development.
Responsibilities
- 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
Skills
- BS in EE/CE/CS (or equivalent experience)
- 5+ years of strong 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)
