TL;DR · 5G/6G Modem Software Engineer

As a member of the Modem SW team, the #5G/6G Modem Software Engineer will design, develop, and optimize modem firmware and software for LTE, 5G-Advanced protocol stack layers, and early 6G research prototyping. The role involves developing real-time embedded software on proprietary RTOS like QuRT, implementing 3GPP-compliant features across L1/L2/L3 layers, and creating resource management algorithms using custom scripting languages for dynamic modem reconfiguration. Key responsibilities include debugging complex field issues using protocol logs and trace tools, performing performance profiling in constrained environments, and collaborating on modem bring-up. The candidate must possess strong C/C++ programming skills, a solid understanding of wireless communication principles such as OFDM and MIMO, and experience with multi-threading and memory management. This role addresses the technical challenge of delivering high-performance connectivity and AI-driven optimization for mobile and IoT devices.

What you'll do

  • Design, develop, debug, and optimize modem firmware for LTE, 5G-Advanced, and 6G research prototyping.
  • Develop real-time embedded software on proprietary RTOS with strict latency and throughput constraints.
  • Implement 3GPP-compliant features across L1, L2, and L3 protocol stack layers.
  • Create real-time scheduling and resource management algorithms for modem performance.
  • Use custom scripting languages to dynamically reconfigure the modem based on network conditions and AI signals.
  • Resolve complex field issues and interoperability problems using protocol logs and trace tools.
  • Write and maintain unit tests, integration tests, and automation scripts to ensure software quality.

What we're looking for

  • Bachelor's degree in Computer Science, Electrical Engineering, Electronics/Communication Engineering, or a related field.
  • 1–2 years of academic or industry experience in C/C++ programming.
  • Foundational understanding of embedded systems, real-time operating systems, and data structures and algorithms.
  • Basic knowledge of wireless communication concepts or digital signal processing fundamentals.
  • Master's degree in Computer Science, Electrical Engineering, Electronics/Communication, or Wireless Communications (preferred).
  • 2+ years of industry experience in embedded software development for wireless/telecom systems (preferred).
  • Experience with RTOS, object-oriented design, and 3GPP 5G NR / LTE specifications (preferred).
  • Familiarity with modem protocol stacks, AI/ML fundamentals, debugging tools, and version control systems (preferred).
