Requisition Id 1757
Computational requirements in bioscience are now reaching the level of the traditionally compute-intensive fields such as particle physics and astronomy. The Biosciences Division at Oak Ridge National Laboratory (ORNL) has initiated a new effort to meet this need by employing high-performance computing to help overcome simulation and advanced analytics bottlenecks. This type of work has recently been awarded a Gordon Bell Prize. We seek a postdoctoral researcher with experience in computer science with an interest and cursory understanding of biology and bioscience applications to help a team of computational biologists develop high-performance workflows on our clusters and supercomputers. The researcher will devote 50 % of their time to this project, and another 40 % to work on programming environment infrastructure for the Frontier exascale computer at the Oak Ridge Leadership Computing Facility (OLCF). The researcher will also be allowed to devote 10 % of their time to a personal research project of choice that will have access to ORNL compute facilities.

Major Duties / Responsibilities
The selected candidate will join a multi-disciplinary team of investigators undertaking broad, integrated approaches to using bioinformatics at a large scale to discover gene functions and understand metabolic responses of organisms to their environment. In addition, the candidate will work with OLCF teams to test, validate, and prepare tools, libraries, compilers, and applications for optimal deployment on the Frontier machine. The candidate will be expected to interact with computational scientists, experimentalists, computer scientists, vendors and system administrators to create and test programs and tools, analyze program output, make predictions and validate findings.

A Ph.D. in computer science or a related field is required. Prior knowledge and demonstrated expertise in the following is required:

- Python, C/C++, git, Make
- Parallel programming models such as OpenMP and MPI
Prior knowledge and demonstrated expertise in one of the following areas is desirable:

- Scientific workflows
- High-performance computing
- Familiarity with GPU programming (e.g. CUDA, etc.) and tools (profilers, debuggers)

The primary responsibilities of the selected candidate will be to develop and modify bioinformatics programs and workflows to run on massively parallel systems, deploy and test programming environments on experimental supercomputing systems, and engage in personal research in the computational sciences. Proficiency with Python, C/C++ and Linux is essential. Experience with parallel programming, computing clusters and job schedulers, compilers, and building and profiling codes on HPC systems is also desirable. A proven publication record as well as excellent oral and written communication skills and ability to work in a multidisciplinary team are required.

Applicants cannot have received their Ph.D. degree more than five years prior to the date of application and must complete all degree requirements before starting their appointment.

This position is a full-time assignment for 12 months, contingent on successful performance and continued funding.
