Senior Research Engineer, Embedded Software

Overview

We are seeking a highly motivated and technically qualified Senior Research Engineer, Embedded Software. In this role, you will bridge the gap between low-level hardware drivers and the O-RAN application layer, enabling seamless integration of the O-RU software stack. Working closely with the Principal Architect and cross-functional engineering teams in Plano lab, you will analyze and adapt third-party Max Linear SDKs, design and implement robust Hardware Abstraction Layers (HAL), and develop clean, testable APIs that support upper-layer real-time radio applications.

This is a critical systems integration role requiring strong embedded Linux expertise, deep understanding of vendor SDKs, and the ability to deliver maintainable software interfaces in a complex telecom environment.
