• Develop and maintain one or more microservices within the device management agent, in C and C++ on RDK-B.
• Implement and maintain device data model parameters and USP protocol behavior across supported hardware platforms.
• Interface with the device's Wi-Fi and cellular subsystems through RDK and RBUS to configure them, query state, and report it upstream.
• Build and maintain the containerized services that run on the device, delivered through a Kubernetes-based packaging and deployment pipeline.
• Write unit tests for new and changed code and extend our automated test coverage.
• Debug across the device software stack, from log analysis and root cause investigation through to fix verification.
• Support device maintenance releases, including test support, firmware validation, and release verification.
• Work with OEM partners on defect triage and reproduction.
• Improve how we collect data and logs from the field so issues can be triaged and resolved faster.
• Contribute ideas that improve how we build, test, and deliver device software.
• Document your code, the data model and device behavior.

This role is essential for designing, implementing, and deploying scalable software solutions that meet customer requirements and support high availability environments. The role involves collaborating with engineering teams to develop software components using technologies such as virtualization, microservices, software-defined networking, network functions virtualization, and broadband device management. This position requires independent development of software components and understanding system protocols, data flows, and technology interactions, including those supporting broadband customer premises equipment (CPE).

Success is measured by the ability to deliver technical solutions, produce clear documentation, and contribute to technology strategy and innovation. The work impacts the organization by enabling advanced software systems that improve operational efficiency and support business goals.
