Embedded Software Engineer - Broadband CPE

T-Mobile • Overland Park, WA

2d • $92,500 - $166,800

About The Position

T-Mobile is hiring an Embedded Software Engineer to develop software for broadband customer premises equipment (CPE), including gateways and mesh extenders used with T-Mobile Home Internet. The role is part of a small development team within a larger program and contributes to device software from the start.

The engineer develops device agents in C and C++ on the RDK-B platform, using Broadband Forum open USP standards and a microservice architecture. The agents manage, monitor, and troubleshoot devices, and interface with Wi-Fi and cellular subsystems through RDK and RBUS. The role involves maintaining containerized services delivered through a Kubernetes-based packaging and deployment pipeline, debugging across the device software stack, and supporting maintenance releases and OEM defect investigations. This position does not involve writing Wi-Fi drivers or modem firmware.

The role also includes unit testing, automated test coverage, firmware validation, field data and log collection improvements, technical documentation, and contributions to development and delivery processes. The engineer collaborates with technical teams and OEM partners, and may perform other duties or projects as assigned. Travel is required.

Responsibilities

• Develop and maintain one or more microservices within the device management agent using C and C++ on RDK-B.
• Implement and maintain device data model parameters and USP protocol behavior across supported hardware platforms.
• Interface with device Wi-Fi and cellular subsystems through RDK and RBUS to configure them, query state, and report it upstream.
• Build and maintain containerized device services delivered through a Kubernetes-based packaging and deployment pipeline.
• Write unit tests for new and changed code and extend automated test coverage.
• Debug across the device software stack, including log analysis, root cause investigation, and fix verification.
• Support device maintenance releases, including test support, firmware validation, and release verification.
