By Light Professional IT Services LLC readies warfighters and federal agencies with technology and systems engineered to connect, protect, and prepare individuals and teams for whatever comes next. Headquartered in McLean, VA, By Light supports defense, civilian, and commercial IT customers worldwide.

The Integration Engineer will play a critical role in the planning, development, and execution of delivery orders (DOs), contributing as a hands-on engineer. This individual will be responsible for assisting in systems engineering efforts across the full lifecycle, from initial concept and requirements development through testing, verification, and final delivery with a focus on bringing together components and systems from various vendors and other sources to make a complete system that will meet the customer's needs. The ideal candidate has solid experience in systems engineering, enjoys solving complex technical problems, and can work independently with moderate supervision.

This role requires close collaboration with internal teams, outside suppliers, and government stakeholders and involves occasional travel to customer sites or supplier locations. A hybrid work environment is possible when not required to be on-site for customer meetings or test events. The program reserves the right to require on-site work if program execution and success dictates.

This is a full-time position. Days and hours of work are typically Monday through Friday, 9:00a a.m. to 5 p.m. Occasional evening and weekend work may be required as job duties demand.
