Role Summary
Own the integration layer between Linux user space, programmable logic, and radio control software for a UHD-based platform with Mavenir-style processing split. This engineer will bridge Yocto build systems, XSA-to-DTSI hardware description flow, UIO/register access, and RTL device integration for production-grade radio subsystem control.Key Responsibilities
Build and maintain Yocto layers/recipes for UHD-based images and integration components. Integrate FPGA hardware exports (XSA) into Linux device-tree flows (DTS/DTSI), including address maps, interrupts, clocks, and memory regions.
- Implement and validate RTL device exposure to software (UIO, kernel interfaces, register maps, driver hooks as needed).
- Develop/maintain C++ integration code in UHD-adjacent control paths for register access, device discovery, and diagnostics.
- Align software control flow with Mavenir-style PS integration patterns (process orchestration, CLI/tool-driven configuration, control plane interaction).
- Debug end-to-end data/control path issues across FPGA, boot flow, Linux, and user-space applications.
- Produce integration documentation, bring-up checklists, and reproducible test workflows for CI/lab use.
Job Requirements
1.5+ years in embedded Linux and SoC/FPGA system integration.
2.Strong Yocto/Open Embedded experience:
- custom layers, bbappend, image recipes, dependency management, reproducible builds.
3.Device tree proficiency:
- XSA to DTSI workflows, node binding, address translation, interrupt wiring, overlay/debug.
4.FPGA-software interface experience:
- MMIO/register maps, UIO/devmem/debug tooling, AXI-based peripheral integration.
5.C/C++ systems programming on Linux (cross-compiled targets).
6.Practical board bring-up and lab debugging skills:
- serial console, bootloader/kernel logs, oscilloscope/logic analyzer familiarity.
7.Version control and release hygiene (Git, review discipline, traceable change logs).
Nice-to-Have
- Prior UHD/USRP or SDR stack integration.
- O-RAN RU stack familiarity, including split architecture and control/management workflows.
- RFNoC awareness (for comparison/migration context even if not used in active path).
- CI/CD for embedded platforms (artifact caching, sstate strategy, hardware-in-loop tests).
- Experience with performance profiling and latency tuning across PS-PL boundaries.
