Full job description

Join our Team

Ericsson Enterprise Wireless Solutions is building its first India‑based modem engineering team in Bangalore, leading end‑to‑end modem baseband, platform, and firmware architecture for next‑generation enterprise and industrial IoT solutions. This founding team works closely with global Ericsson engineering organizations and Qualcomm partners on advanced SDX‑based platforms.

As a Principal Modem Firmware Architect, you will own the complete modem firmware architecture for SDX‑based LGA modem modules, drive Qualcomm AMSS/MPSS integration strategy, and provide technical leadership across modem software, hardware interfaces, and platform components. This is a ground‑up opportunity to define architecture, influence long‑term technology direction, and deliver carrier‑grade, high‑performance 5G platforms deployed at a global scale.

In this role, you will operate at the system‑architecture level, bridging modem firmware, baseband platforms, RF subsystems, and product requirements. You will define software architecture, guide implementation across teams, and serve as the primary technical interface to Qualcomm and key hardware partners.

The role requires deep modem expertise, strong architectural judgment, and the ability to influence design decisions across cross‑functional and geographically distributed teams.

Lead Qualcomm AMSS/MPSS integration, customization, and long‑term upgrade strategy
Define architectural guidelines for baseband platform, RF, power management, and system interfaces
Drive cross‑team technical alignment across firmware, hardware, RF, and platform teams
Serve as the primary technical contact with Qualcomm and modem hardware partners
Review and guide complex design decisions, trade‑offs, and performance optimizations
Debug and resolve critical system‑level issues across HW/FW/SW boundaries
Influence modem roadmap decisions, technology choices, and future platform evolution

Required Skills

10+ years of modem firmware / baseband platform experience, including architectural ownership
Strong hands‑on experience with Qualcomm SDX / MSM modem platforms
Deep understanding of modem subsystem architecture (ARM cores, DSP, hardware accelerators)
Expert knowledge of Qualcomm AMSS/MPSS software stack and integration models
Strong C/C++ expertise for large‑scale, real‑time embedded systems
Proven experience with system‑level debugging using JTAG, trace tools, and lab instrumentation
Ability to lead technical discussions, reviews, and cross‑team design alignment

Preferred Qualifications

Experience across multiple modem generations and carrier deployments
Background in RF, power optimization, and performance‑critical modem features
Experience driving technical relationships with chipset and hardware vendors
Proven mentorship or technical leadership experience
Master’s degree or higher in Electrical Engineering, Computer Engineering, or related field
