As a Support Engineering III, you will define, architect, and implement high-capacity optical network designs for the 1FINITY platform and other Fujitsu transport solutions. Working at the intersection of system design and field integration, you’ll transform customer and business requirements into detailed optical network blueprints that ensure seamless deployment and operational excellence.

This position functions upstream of field and support implementation teams — designing the photonic foundation that drives downstream success. You will collaborate closely with Support Engineers, Project Managers, and Customer Engineering teams to deliver robust, scalable, and high-availability DWDM/ROADM/OTN networks that support today’s digital transformation.

You’ll take ownership of link-level design, optical margining, service modeling, configuration strategy, and performance validation, ensuring that each solution is technically sound, cost-effective, and operationally ready for live deployment.
