Lead Engineer

The Lead Engineer is responsible for driving system integration strategy and execution across wireless communication products, ensuring high-quality and timely delivery. The role combines hands-on technical leadership, cross-functional coordination, and ownership of integration outcomes across 4G eNodeB and evolving 5G gNB systems. The Lead Engineer leads integration planning, validation strategy, and complex issue resolution, while mentoring engineers, managing priorities, and ensuring alignment with architectural, process, and release goals. Tejas wireless team has developed high-capacity LTE macro eNodeB, 5G NR gNodeB along with Radio Units as part of end-to-end integrated solutions to their customers. Our systems are already deployed in customer’s commercial network and engineers are working on to enhance the capacity and improve system level performance. Tejas Networks has invested in Wireless product development since 2012 with a vision to create globally deployable telecom RAN solutions. Several of the key components developed by the Wireless R&D team have been installed and commissioned across three continents. We are an active partner for 5G in the Indian Ecosystem and have significantly contributed to India’s standardization efforts in 3GPP, through TSDSI. The wireless team has over 100 patents. As part of the wireless team, you will work on developing products for the next generation of wireless systems.
