This is a BSP-focused leadership role for an engineer who brings deep expertise in board bring-up, Linux kernel, and platform software on ARM-based SoCs . The role centres on owning the software platform layer for O-RU products built on Xilinx MPSoC, RFSoC, or equivalent SoCs. FPGA experience is welcome and advantageous, but the core mandate is delivering a robust, production-grade BSP and embedded Linux stack that enables the full O-RU signal chain and O-RAN management plane. You will lead a team of BSP and embedded software engineers, define the platform software architecture, and collaborate closely with hardware, RF, PHY, and FPGA teams to bring O-RU platforms from silicon to production.

Key Responsibilities

• Own end-to-end BSP development for O-RU platforms based on Xilinx ZU+ MPSoC / RFSoC or other ARM Cortex-A/R SoCs.
• Lead hardware bring-up from bare board to functional system: power sequencing, clocking, DDR training, peripheral initialization.
• Develop and maintain FSBL (First Stage Bootloader), PMU/PLM firmware, ARM Trusted Firmware (TF-A), and U-Boot for Zynq UltraScale+ and Versal platforms.
• Author and maintain device tree sources (DTS) for all platform peripherals: RF Data Converter tiles, DMA engines, Ethernet MACs, UART, I2C, SPI, GPIO.
• Develop production-grade Linux BSP using PetaLinux / Yocto with custom meta-layers for O-RU hardware.
• Collaborate with hardware team on schematic reviews, signal integrity, and component selection for SoC peripherals.
• Port, customize, and maintain Linux kernel for target SoC platform aligned with LTS releases (5.15, 6.1, 6.6).
• Develop Linux kernel drivers for platform-specific peripherals: Xilinx RFDC (RF Data Converter), AXI DMA / MCDMA, high-speed Ethernet (10G/25G), PTP hardware clock.
• Debug kernel panics, memory corruption, latency spikes, and boot failures using JTAG, GDB, ftrace, perf, and crash analysis.
• Profile and optimize BSP-level latency to meet O-RAN T2a / Ta3 timing requirements from fronthaul interface to RF chain.
• Develop and maintain IEEE 1588v2 PTP (G.8275.1 Telecom Profile) and SyncE software stack for O-RAN S-Plane timing compliance.
• Build and maintain Yocto-based Linux distro with BSP layer, security hardening (dm-verity, secure boot, TrustZone), and OTA update support via SWUpdate.
• Integrate Xilinx PL (Programmable Logic) IP blocks — eCPRI framer, IQ DMA, beamforming control — with PS-side Linux drivers via AXI4-Lite and AXI4- Stream
• Represent BSP platform in cross-functional reviews with RF, PHY, O-RAN stack, and product teams.

Job requirements

• 8+ years of core BSP & Embedded Linux Experience with B.E. / B.Tech or M.Tech in Electronics & Communication, Electrical Engineering, or Computer Engineering.
• Deep expertise in BSP development for ARM Cortex-A/R SoCs.
• Hands-on Linux kernel internals: memory management, DMA subsystem, interrupt handling, device tree, clock framework, power management (PM / PSCI).
• Strong C programming skills for kernel and embedded firmware development.
• Scripting: Python, Bash, Tcl for build automation, test scripting, and hardware bring-up utilities.
• Hardware debug skills: JTAG (Lauterbach, Xilinx HS3 / HS2), oscilloscope, logic analyser, serial console bring-up.
• Familiarity with O-RAN Alliance O-RU architecture and WG4 fronthaul split (eCPRI, CUS-Plane, M-Plane, S-Plane).
• C++ experience for developing BSP-level user-space services, configuration daemons, or test harnesses.

Benefits:

• Competitive salary and stock options.
• Learning and development opportunities.
• Employer-paid health Insurance.
• Earned, Casual, Sick & parental leaves.
