Job Overview
Lead the design, validation, and deployment of innovative technical solutions that evolve and future-proof T-Mobile’s next-generation network and systems. This role requires deep technical expertise and strategic oversight across 5G application design, cloud networking, and DevOps automation. You will be responsible for architecting and maintaining scalable, high-reliability solutions across network domains, including 5G Core, edge computing, and telco-grade platforms. A key focus will be designing systems that span both the infrastructure (IaaS) and platform (CaaS) layers of the telco cloud—leveraging technologies such as Kubernetes, OpenStack, and hyperscaler environments (AWS, Azure, GCP). The position involves evaluating complex business and technical requirements, assessing trade-offs, and delivering designs that enable 5G use cases like private networks, network slicing, URLLC, IoT, and MEC. You will also define DevOps workflows, CI/CD pipelines, and automation frameworks to streamline deployment and performance optimization. Strong judgment and initiative are essential, as you will independently drive design strategies, develop tooling, ensure compliance, and collaborate across engineering, operations, and product teams. Excellent communication skills are required to influence across organizations, present technical roadmaps, and guide cross-functional stakeholders. Experience with NFV, CNFs, SBA, and orchestration frameworks such as ONAP or ETSI MANO is highly desirable, along with a proven track record in real-world 5G telco deployments.
