RAN Test Engineer III

TeleWorld Solutions is seeking a RAN Test Engineer III to join our team! Join a cutting-edge wireless engineering team driving the future of connectivity. As a RAN Test Engineer III, you will play a critical role in validating next-generation LTE and 5G NR Radio Access Network (RAN) technologies. This role sits at the intersection of product validation, performance engineering, and customer engagement, ensuring seamless interoperability and best-in-class network performance.You’ll work hands-on in lab and customer environments, collaborating with global teams to bring innovative wireless solutions to life.Who We Are: The Architects of What Connects UsYou find the signal in the noise of data.We build the signal itself.We are TeleWorld Solutions, and we are the strategic backbone for the world's most ambitious wireless networks. We're not just consultants; we're the engineers, designers, and problem-solvers that operators, OEMs, and tower giants trust to bring their boldest visions to life.Our playground is the invisible architecture of connection-from vast macro networks to the hyper-precise world of DAS, Small Cells, and Wi-Fi. With a legacy ofhundreds of thousands of successful implementations, we help our clients navigate the entire lifecycle of their network: from the first line of a design to the final optimization, and every critical decision about performance and value in between.Why does this matter to you?The complex data you will master-the CDRs, network KPIs, and customer signals-flows from the very infrastructure we design and optimize. You won't just be analyzing abstract numbers; you'll be interpreting the digital heartbeat of networks that we helped bring to life. Your insights will directly influence the next generation of those networks.Here, your work as a data storyteller is powered by deep, tangible engineering excellence. You provide the 'what' and 'why.' We provide the 'how' on a global scale.Welcome to the engine room of connection.
