Senior R&D Engineer - Astrodynamics/Trajectory Optimization

Location: Exton
Posted on: June 23, 2025

Job Description:

When visionary companies need to know how their world-changing ideas will perform, they close the gap between design and reality with Ansys simulation. For more than 50 years, Ansys software has enabled innovators across industries to push boundaries by using the predictive power of simulation. From sustainable transportation to advanced semiconductors, from satellite systems to life-saving medical devices, the next great leaps in human advancement will be powered by Ansys. Summary Ansys Government Initiatives (AGI) is seeking an experienced, top-performing Senior Astrodynamics Engineer to contribute to the design and development of its Systems Tool Kit (STK) Astrogator tool. Astrogator provides everything mission planners need to develop, optimize, and validate flight-ready trajectory solutions and reveals mission-critical insights that can decrease overall program costs. Astrogator is used to develop, refine, and validate high-fidelity trajectory designs, and to compute updates to planned maneuvers during operations in response to observed flight performance. Astrogator has been used on missions ranging from LEO to GEO, from the Sun to Arrokoth, and many places in between. In this role, the Senior Astrodynamics Engineer will work closely with the contributors to our other flight dynamics product, Orbit Determination Tool Kit (ODTK). ODTK provides highly accurate orbit estimates from processing real or simulated tracking data and is used throughout the engineering life cycle, from mission design through operations. In this role, the Senior Astrodynamics Engineer will use their expertise to develop strategic plans, refine requirements, and implement software solutions to achieve development objectives. This position is not eligible for immigration sponsorship.
