The Engineer, Forward Deployment is a hands-on technical practitioner who embeds within a T-Mobile business unit to design, build, and iterate on net-new agentic AI solutions. These solutions are developed against requirements defined and scoped by TPMs and business unit stakeholders. Forward Deployment Engineers (FDEs) write code, run experiments, debug production systems, and work closely with business unit stakeholder teams to deliver AI solutions that achieve stated business outcomes.
FDEs typically work alongside a Senior FDE who owns the domain relationship and sets technical direction. The Engineer is responsible for the execution layer: building system integrations, tuning prompts, running A/B cohorts, and delivering against validated ROI targets for the domain. Performance is measured by contribution to validated return on investment outcomes for each domain assignment — not by activity or ticket volume. This role reports to the Manager or Senior Manager, Forward Deployment Engineer within the assigned pod.
We pride ourselves on fostering a culture of innovation, advocating for agile methodologies, and promoting transparency in all that we do. Join us in embodying the spirit of the 'Un-carrier' and make a tangible impact! If you're up to the challenge, apply today!
AI System Deployment & Tuning: Implement, configure, and iteratively tune net-new agentic AI solutions deployed in the assigned business domain, working against requirements defined and delivered by TPMs. Adapt solution behavior, prompt layers, and escalation logic based on live operational feedback on a weekly cycle.
