Platform Development Engineer

Mavenir is building the future of networks and pioneering advanced technology, focusing on the vision of a single, software-based automated network that runs on any cloud. As the industry's only end-to-end, cloud-native network software provider, Mavenir is transforming the way the world connects, accelerating software network transformation for 250+ Communications Service Providers in over 120 countries, which serve more than 50% of the world’s subscribers. 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. Accessibility Mavenir is committed to working with and providing reasonable accommodation to individuals with physical and mental…
