At Jacobs, we're challenging today to reinvent tomorrow by solving the world's most critical problems for thriving cities, resilient environments, mission-critical outcomes, operational advancement, scientific discovery and cutting-edge manufacturing, turning abstract ideas into realities that transform the world for good.

Your impact

Knack Works, a Jacobs Company, has an opening for a Network Engineer (Campus Area Network/Local Area Network (CAN/LAN)) to support our government customer's global enterprise networks. The CAN/LAN service network architecture provides solutions for modernizing network components while supporting service delivery for customer requirements in a mission-focused operational enterprise. Our team is completely replacing a global enterprise network while providing design, engineering, and transition for a wide range of customer network requirements. This is a unique and rare opportunity to build and transition critical operations to a modern service provider network architecture.

The job duties of the Network Engineer (CAN/LAN) are as follows:

* Interpret customer requirements and apply standard design approaches for service delivery. Fully document designs with diagrams, bill of materials, cabling sheets, configurations, and other supporting documents.
