Job description

Senior Wireless Software Engineer (PHY Layer)

Software - Pune, India - Full Time

You will be working on the design, development, and integration of calibration software modules for wireless communication systems using multiple antennas.

Design, development, integration, and testing calibration software modules for a next-generation fixed wireless broadband system. The primary focus is functionality in layer 1 of the proprietary 5G protocol, such as channel estimation, IQ imbalance correction, and LO leakage cancellation.

You will develop software running on both the base station and user equipment of a broadband wireless access system for various multicore DSP/ARM processors and real-time operating systems. You will collaborate closely with L2/L3 software groups and FPGA/ASIC teams to deliver cross-layer features.

Job Responsibilities:

• Design and develop scalable PHY/Calibration software modules on multi-core DSP/GPP using C/C++
• Define and develop unit test vectors using Matlab and C++ for the software modules and unit test extensively to deliver flawless modules
• Test and validate the performance of the software modules on the real system.
• Develop scripts to qualify the RF board testing

Required Skills & Experience:

• MS or PhD in Electrical Engineering/Computer Science with an emphasis in wireless communication and/or digital signal processing
• 5-12 years of industry experience in DSP software development for wireless communication systems (such as 5G, LTE, WiFi, or similar proprietary protocols)
• Formal understanding in communication and signal processing theory and techniques, with strong mathematical background in linear algebra
• Experience in developing and implementing wireless communications systems in at least one of the following areas:
  • Array signal processing such as beam‑forming and MIMO techniques for an OFDM system
  • Physical/MAC/baseband layer software implementation for LTE/5G.
  • Adaptive equalization, receiver synchronization, signal identification and recovery
• Experience with OFDM based system implementation
• Experience with version control systems, collaboration tools (wikis, ticket systems)
• Experience in scripting languages (python, bash, etc)

Knowledge and Skills:

• Formal understanding of communication and signal processing theory and techniques, including OFDM communication systems, and a strong mathematical background in linear algebra
• Strong background in C, C++, and Python programming
• Experience with software development for multi-core embedded systems, including real-time operating systems (RTOS), memory and cycle optimization, caches, multi-threaded programming, inter-process communication, and HW/SW interaction
• Comprehensive knowledge of algorithms used in wireless communication systems and related design and implementation in software
• RFIC impairments and compensations SW development and validation
• Calibration procedures for multi-antenna based systems
• Advanced array signal processing techniques, such as beam‑forming and MIMO
• Adaptive equalization, receiver synchronization, signal identification and recovery

Experience with version control systems (Git, Gerrit, Gitlab), and issue tracking and collaboration systems (Jira, Confluence)
