Job Overview The Senior Engineer, Forward Deployment is an experienced technical practitioner who embeds within a T-Mobile business unit and operates with significantly greater autonomy than an Engineer FDE.

This role bridges deep hands-on engineering with emerging leadership accountability. Performance is measured by validated return on investment outcomes for the domain and by the quality and impact of the delivery team supported. This role reports to the Manager or Senior Manager, Forward Deployment Engineer within the assigned domain.
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!
