Northrop Grumman Propulsion Systems and Controls (PS&C) facility in Elkton, Maryland began solid-propellant rocket operations in 1948. Today, the Elkton PS&C facility designs, develops, and produces solid-propellant propulsion, ordnance and motion controls systems in programs professionally managed for a wide variety of Government and commercial customers. The facility also serves as the hub for offsite engineering and test facilities in Ronkonkoma, NY and Palm Beach Gardens, FL.

This position will perform thermo-structural analysis simulation and modeling efforts under the guidance of a Staff Engineer to support design activities across all Northrop Grumman, Propulsion Systems and Controls, Elkton Operations product lines. These simulations include development of thermo-structural models, gridding, selection of boundary conditions and constraints, selection of applicable material properties, selection of proper simulation code and methodology.

Job Responsibilities:

• Develop analytical approaches to assist in the resolution of unique structural/thermostructural mechanics issues.  Assist in design effort of test articles to provide necessary data for full scale applications. Provide structural mechanics, material specialist services to IPT working group
• Taking role in developing methodologies, interpretation of analytical results, and recommendations for design improvement.
• Preparation of technical reports and presentations of work product to both internal and external customers.
• Provide technical assessments of test hardware and test data
