Ericsson Enterprise Wireless Solutions is building its first India‑based modem engineering team in Bangalore, focused on end‑to‑end modem baseband and platform development in collaboration with global Ericsson teams and Qualcomm partners. This founding team is shaping next‑generation enterprise and industrial 5G solutions on advanced SDX‑based platforms.

As a Modem Baseband Platform Engineer, you will design, develop, and optimize the low‑level modem baseband platform software for SDX‑based LGA modem modules. This is a ground‑up opportunity to influence platform architecture early, take strong technical ownership, and deliver high‑performance, power‑efficient 5G modem platforms deployed at a global scale.

What you will do:

  • Design and implement baseband platform software architecture for SDX-based modules
  • Develop hardware abstraction layers (HAL) for Qualcomm chipset components and peripherals
  • Optimize memory management, DMA operations, cache utilization, and power management (DVFS, sleep/wake)
  • Develop and optimize interrupt service routines, real-time task scheduling, and DSP firmware integration
  • Debug complex HW/SW issues using JTAG, trace tools, and logic analyzers
  • Perform performance profiling and optimization across CPU, memory, and power domains
  • Collaborate on board bring-up, validation, and create platform documentation

The skills you bring:

  • 5+ years embedded baseband/platform development; 3+ years on Qualcomm modem platforms
  • Deep expertise in Qualcomm baseband (SDX/MSM series), modem subsystem architecture (DSP, ARM, accelerators)
  • Expert-level HAL development and RTOS experience (REX, ThreadX, FreeRTOS)
  • Advanced C/C++ for real-time systems; strong memory management and cache optimization skills
  • Experience with DMA controllers, interrupt handling, power management, and clock control
  • Hardware/software co-design experience and system-level thinking
  • Proficiency with JTAG debugging, trace tools, logic analyzers, and oscilloscopes
  • Excellent problem-solving and communication skills

Preferred:

  • SDX82/85/72/65/55 chipsets; Hexagon DSP programming; ARM Cortex-A/R expertise
  • Hardware accelerator integration (crypto, compression); bootloader development (U-Boot, LK)
  • Thermal management, multi-core synchronization, IPC, AMBA protocols (AHB, AXI)
  • PCIe, USB 3.0, UART, SPI, I2C, SDIO driver development
  • Lauterbach Trace32, Segger J-Link, ARM DS, profiling tools (gprof, perf)
  • Master's degree in Embedded Systems, EE, or CE
