Platform Development Engineer

6001 Mavenir Systems Private Limited - BLR office; Bengaluru; On-site; INR 900,000 - 1,500,000; Full time

Job summary

Mavenir Systems, Inc. is seeking a hands-on Embedded Linux engineer to own the integration layer between Linux user space, programmable logic, and radio control software for a UHD-based platform.

You will bridge Yocto build systems, XSA-to-DTSI hardware description flows, UIO/register access, and RTL device integration for production-grade radio subsystem control. Strong C/C++ and lab bring-up skills are essential.

Qualifications

• 1.5+ years in embedded Linux and SoC/FPGA system integration.
• Strong Yocto/Open Embedded experience: custom layers, bbappend, image recipes, dependency management, reproducible builds.
• Device tree proficiency: XSA to DTSI workflows, node binding, address translation, interrupt wiring, overlay/debug.

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 description

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.
• Strong Yocto/Open Embedded experience: custom layers, bbappend, image recipes, dependency management, reproducible builds.
• Device tree proficiency: XSA to DTSI workflows, node binding, address translation, interrupt wiring, overlay/debug.
• FPGA-software interface experience: MMIO/register maps, UIO/devmem/debug tooling, AXI-based peripheral integration.
• C/C++ systems programming on Linux (cross-compiled targets).
• Practical board bring-up and lab debugging skills: serial console, bootloader/kernel logs, oscilloscope/logic analyzer familiarity.
• 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.
