Job Overview
The Principal Engineer Commercial AI Forward Deployment is the senior technical engineer on T-Mobiles most complex commercial AI engagements and often the first technical point of contact a strategic customer works with. The role supports T-Mobiles commercial AI programs. Responsibilities include supporting Kinetic Edge AI (KEAI) and the broader Physical AI program but are not limited to them and will extend to AI applications T-Mobile sells to business customers. This person embeds with customer teams to turn ambiguous often unprecedented use cases in areas such as smart city and public safety utilities industrial automation and autonomous mobility into working systems on T-Mobiles network edge compute and cloud. They are equally comfortable writing an inference pipeline for a robotics workload explaining network slicing to a customer executive and telling a business team when a timeline does not fit the physics of RF propagation or the GPU capacity available. This is a build-and-lead role not an advisory one. The Principal Engineer writes and ships production code on the hardest problems owns technical direction for the sensor and vision data-at-scale layer (ingestion fusion fine-tuning training) on their engagements and sets the engineering standards other FDEs follow. They decide with AI Engineering which field-built components are ready to graduate into the platform. Success is measured by working deployments on the most complex engagements production stability and the amount of field work that becomes reusable platform capability.

Job Responsibilities:

• Serve as the lead technical engineer on the most complex customer engagements setting the technical approach where no industry playbook exists.

• Write and ship production code on the highest-risk parts of each engagement such as multi-sensor fusion real-time edge inference device and network integration and performance tuning.

• Own technical direction for the sensor and vision data-at-scale layer on assigned engagements including ingestion fusion fine-tuning and training built to platform standards from day one so productization is a graduation not a rewrite.

• Make build decisions that span workstreams and teams partnering with the Principal Architect on solution design and with Network RAN and Core engineering on connectivity and edge compute.

• Keep customer and internal business commitments grounded in what the network edge infrastructure and current AI capabilities can deliver and explain tradeoffs in plain language executives can act on.

• Define production-readiness criteria evaluation methods and operational standards for field deployments and lead root cause analysis and post-mortems for major incidents.

• Decide with AI Engineering and product owners which field-built components graduate into the platform and bring the product roadmap evidence drawn from multiple deployments.

• Provide technical leadership without formal authority: direct the technical work of Sr Engineers and Engineers review critical code and raise the hiring bar for the FDE team.

• Also responsible for other duties/projects as assigned by business management as needed.
