## Description

The Senior LO Mission Systems Integration Engineer will lead design, integration, analysis, test, and production activities for low observable materials, structures, apertures, sensors, and radomes for mission systems. The role requires strong technical leadership, independent execution of complex tasks, advanced use of computational electromagnetic (CEM) solvers, and the ability to produce and defend technical results with minimal oversight., * Lead design, modeling, and analysis efforts for LO materials, coatings, structures, and integrated mission systems to meet signature reduction and performance requirements.

 * Independently apply CEM solvers (e.g., FEKO, HFSS, CST, WIPL-D, xFDTD, or equivalent) to model antennas, apertures, radomes, and LO treatments; perform design optimization and trade studies.
 * Drive integration of LO treatments with mechanical, thermal, and sensor/antenna system constraints; identify and mitigate producibility, testability, and sustainment risks.
 * Plan, execute, and oversee laboratory and field tests (anechoic chamber measurements, antenna/radome characterization, RCS measurements); lead data collection, reduction, and validation activities.
 * Develop and validate predictive models, reconcile simulations with measurements, perform uncertainty quantification, and provide actionable recommendations to engineering and program leadership.
 * Produce high-quality technical documentation: test plans, test reports, technical memoranda, design reviews, and customer briefings.
 * Mentor and provide technical oversight to junior engineers and technicians; ensure adherence to engineering processes, quality standards, and configuration control.
 * Collaborate across multidisciplinary teams (structures, materials, manufacturing, RF/antennas, systems engineering) to deliver integrated system solutions on schedule and within cost., Outdoor Campus Maintenance Team, Start ASAP
