TeleWorld Solutions is seeking an RF Design Engineer IV/Lead SME to join our team. The RF Design Engineer IV/Lead SME is a senior-level technical expert responsible for designing, optimizing, and enhancing 4G, 5G, Fixed Wireless Access (FWA), and CBRS networks. This role requires deep hands-on experience with ATOLL (including advanced modules such as ACP, Aster, Monte Carlo, and prediction modeling) and a strong understanding of RF fundamentals, MIMO/beamforming, link budgets, and antenna behavior.

You will be responsible for greenfield and brownfield RF design, model calibration, RF shaping optimization, and RFDS development. This position is highly collaborative, working onsite daily with customer teams, internal engineering groups, and deployment personnel to meet stringent performance and delivery expectations.

Who We Are: The Architects of What Connects Us

You 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 of hundreds 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.
