Primary Job Functions:

* Design and develop applications based on an internally defined architecture and best practices * Coordinate and communicate with team members throughout the software development cycle - system analysis, design, coding, and testing
* Test, debug and document all code
* Assist with the creation of training materials for products being developed
* Work with system groups to develop new processes for delivering middleware products to the production environment
* Develop parallel HPC parallel applications using C, C++, Fortran, and MPI
* Develop applications in Java and UNIX shell scripts

Job Requirements:

* M.S in Computer Science or PhD in Computer Science with considerable hands-on practical experience in HPC software development
* Demonstrated experience in scientific computing and development
* Knowledge of most common math and algorithms libraries used in scientific parallel computing, including BLAS/PBLAS/CBLAS, LAPACK/SCALAPACK/, BLACS, Boost, STL, and QT
* Required programming languages skills: C/C++, Fortran77/ Fortran90/95, Python, Unix shell scripting languages (BASH primarily)
* In-depth knowledge of UNIX-like (Linux in particular) Operating Systems, including OS memory management (paging, swapping, memory locking, differences between virtual memory and Resident Set, buffers, etc.), OS CPU management (schedulers, policies, priorities, etc.), I/O management, and Linux kernel (i.e., debugging skills and experience in writing device drivers)
* Linux System Administration and Performance Debugging & Optimization, including ability to use tools of the trade to debug/trace/profile programs for memory leaks, bugs, hot spots/performance problems. Fluency in RPM system and ability to create/build RPMs required
* In-depth knowledge and experience in parallel programming, including MPI2 programming skills (with understanding of OpenMPI implementation of MPI2 in particular), as well as OpenMP and MPI-IO. Understanding different levels of parallelism and knowledge of CUDA and OpenCL (i.e., programming on GPU) is highly desirable
* Understanding of file systems (i.e. local FS vs. distributed, vs. parallel)
* Source Code Management Tools & Bug Tracking Tools: SVN, CVS,
* Formal Software Engineering and Computer Science skills and tools, including UML, OCL, Design Patterns, Data Structures and Algorithms
* Networks: Understanding of TCP/IP and UNIX Network Programming and Debugging Skills and tools
* Understanding of database theory and design in general (MySQL, PostrgressSQL, and SQLite)
* Open Source Development Skills including C/C++, FORTRAN, Python, and Perl, on Linux software development and porting skills
* IDE (Integrated Development Environment): Eclipse, Netbeans, Matlab
* Compilers and SDKs: GCC, Intel compilers, debuggers, and libraries, J2SDK, NASM or MASM.
* Understanding of typical cluster composition/architecture, including knowledge of PBS-like resource managers (PBS, OpenPBS, Torque, Moab, SunGrid) and associated schedulers (PBS_SCHED, Condor, Maui, Moab). In-depth knowledge of the above and experience with PBS and scheduler configuration and how that play with MPI and the rest of the SYSTEM that is a Beowulf cluster - is highly preferred. Must be conversant in the implications of using different architectures, number of nodes, and their network interconnects

Preferred Knowledge, Skills, and Abilities:

* Preferred programming languages skills include: HPF, Java, Tcl/Tk, Perl, Intel Assembly, and SQL
* Self-starter who works well in a team environment
* Good verbal and written communication skills
