What This Role Does Not Own

This role does not own formal people management for engineers. Engineering Managers remain responsible for hiring, performance management, compensation input, team structure, and capacity planning.

This role does not own business prioritization or user acceptance. Product / Delivery Managers and business stakeholders remain responsible for intake, priority alignment, backlog readiness, UAT coordination, and business acceptance.

This role does not independently commit delivery dates without alignment with Engineering Managers and Product / Delivery Managers.

This role does not own all AI / ML work across the company unless specifically assigned by GEO leadership. The primary responsibility is Computer Vision technical leadership and production-quality AI / ML implementation for assigned product areas.

This role does not replace Software Architects, DevOps, Data, QA, or Infrastructure ownership. The role will work closely with those teams to make sure Computer Vision solutions are technically sound, production-ready, and supportable.
