TL;DR · 5G/6G Modem Software Engineer

As a 5G/6G Modem Software Engineer on the Modem Technologies Software team, you will design, develop, and optimize modem firmware and software for LTE, 5G-Advanced, and early 6G research prototyping. You will work across L1, L2, and L3 protocol stack layers to implement 3GPP-compliant features, manage real-time scheduling, and develop resource management algorithms using custom scripting languages. The role involves developing real-time embedded software on the QuRT proprietary RTOS while collaborating with hardware teams on modem bring-up and performance optimization. You will utilize C/C++, knowledge of OFDM, MIMO, and digital signal processing to solve complex field issues and interoperability problems. Key technical requirements include experience with multi-threading, memory management in resource-constrained environments, and debugging tools like JTAG or Trace32 to ensure high-quality connectivity for mobile and IoT devices.

What you'll do

  • Design, develop, 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, and debugging tools in embedded environments (preferred).
