AI Engineer (Remote)

Invoke is a consulting and Innovation firm focused on delivering Intelligent automation solutions that solve real operational challenges. We partner with organizations across industries, including the public sector, to design and implement scalable RPA and AI-driven workflows that improve efficiency, accuracy, and reliability. Our teams work hands-on with clients to automate complex processes across a range of systems, from modern applications to legacy environments. A significant portion of our work is within the public sector, where we help government organizations streamline high-volume processes, improve data quality, and modernize critical operations through automation.

INVOKE provides the technology, implementation, and lifecycle expertise to solve business challenges through the lens of intelligent automation technologies like Robotic Process Automation and Artificial Intelligence.

As this role supports public sector clients, U.Build
