Software Developer II
Lebanon, NH

The Software Developer II is responsible for the development the ANSYS CFD solver’s parallel capabilities and other high performance computing infrastructure areas.  The Software Developer II will help to define technical directions and develop products, working closely with other team members and ANSYS teams to ensure the capabilities meet ANSYS strategic needs and our customer requirements.

The position involves developing and maintaining functionality related to the ANSYS CFD solver’s parallel capabilities and other high performance computing infrastructure areas. Responsibilities include:

• Parallel implementation of CFD algorithms and physical models
• Parallel implementation of mesh-related algorithms and partitioning methods
• Development and maintenance of message-passing libraries
• Development and maintenance of dynamic load balancing utilities
• Development of algorithms suitable for distributed computing on GPU
• Development and maintenance of parallel I/O
• Development of automatic error detection and recovery utilities

In addition, the incumbent will optimize the CFD application to achieve high performance for clusters running the Linux and Windows operating systems.  Implementations will be optimized to support both shared and distributed memory platforms.  It is expected that the incumbent will work with hardware vendor partners in tuning the application, as well as porting the application to new hardware including processors and interconnects, and software such as cluster tools and run-time-systems. Part of this work will involve benchmarking and code profiling to assess the performance of the CFD application on high performance hardware. 

The incumbent should maintain a level of technical excellence in the area of parallel processing for CFD through the evaluation of current literature, participation in technical conferences, publications, and interaction with colleagues in the field.  The incumbent may also be called upon to provide high-level support to the product support and development staffs, in the area of parallel CFD.
