Job description

This role requires critical expertise in multiple layers in cellular protocols, experience with UE and/or NW protocols development for various 3GPP technologies is essential. The candidate must demonstrate solid understanding of relevant protocol procedures and network interactions. The duties of this position will include design, develop, and maintain network simulation. You will need to understand the 4G/5G protocols functionality in the respective 3GPP releases and convert that into corresponding protocol implementation and interfaces in the Cellular network simulation systems domain. BS and a minimum of 5+ years relevant industry experience. A good understanding of cellular protocol stacks, particularly 5G. Knowledge of cellular communication standards: 6G, 5G NR, 4G LTE, PHY Downlink/Uplink channels and signals. Software development experience and debugging skills in C/C++. Experience with multi-processing and multi-threading based implementations. Good fundamentals in object-oriented SW design and test techniques and methodologies. Master’s or PhD degree in wireless communication or electrical engineering. Strong understanding of cellular Downlink/Uplink procedures - PDCCH/PDSCH/RACH, DCI, Scheduling Request, HARQ, SRS, CSI, Link adaptation and other scheduler algorithms. Experience in investigating and troubleshooting scheduler issues to optimize the performance of Cellular implementation. Strong analysis and debugging capabilities to diagnose issues and collaborate with development and systems design teams to resolve them. Deep understanding of software engineering principles and core computer science fundamentals. Proficient in scripting or programming languages such as Python and C/C++. A solid grasp of automation tool chain. Working knowledge of various 4G/5G signaling and protocol test equipment (including Keysight, Anritsu, and R&S) and their automation interfaces. Solid knowledge in Layer 2/Layer 3/ NAS and network performance optimization (a plus). Experience with network emulators, silicon prototyping, emulation systems, and virtual platforms a plus. Strong written and verbal communication skills with the ability to articulate complex technical concepts. Ability to modernize legacy systems and adapt to new AI architectures. Highly motivated and self-directed, fast learner, a good team player. Excellent verbal and written communication skills.
