Rockwell Collins Simulation Engineer in Lenexa, Kansas

B/E Aerospace, a wholly owned subsidiary of Rockwell Collins Inc., is a leading manufacturer of aircraft interior products and solutions.

Our Lenexa facility designs and manufactures Oxygen Life Support System products for commercial, military and private business jet aircrafts providing high quality, innovative solutions to enhance aircraft passengers and crew safety and comfort. We strive to make advances in the field of oxygen delivery and consumption technologies for a more reliable system that reduces total weight and cost for our clientele.

As a leader in the aerospace industry, we are growing rapidly and have a number of exciting positions available right now, including a Numerical Methods and Simulation Engineer in our Oxygen & PSU business located in Lenexa, KS.


Reporting to the Engineering Manager, the Numerical Methods and Simulation Engineer will be responsible for the planning and development of numerical methods and oversight of the suppliers involved in subcontracted model validation services. The incumbent will perform decision supporting assignments usually representing a significant portion of a larger project and will select engineering techniques to solve problems and make design recommendations. Furthermore, he/she will develop Numerical Methods and Simulation solutions portfolio with focus on practical problem solving and numerical receipt development, supporting our vision of first pass qualification and 100% production yield of safety critical aircraft systems.
