Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

We have an opening for a Postdoctoral Researcher to perform research in the areas of software compatibility, binary analysis, and dependency solving. You will be part of an interdisciplinary team that analyzes compatibility in different software ecosystems, develops and implements binary analysis tools for extracting application binary interface (ABI) information, and develops new dependency resolution techniques using SAT/SMT solvers. These techniques will support an effort to ease the burden of software integration and dependency management in HPC. This position is in the Center for Applied Scientific Computing (CASC) Division within the Computing Directorate.

Essential Duties
- Perform research in the areas of software engineering (practice and ecosystem analysis), binary analysis, and/or dependency solving.
- Design experiments around testing builds and binary packages from HPC software ecosystems.
- Work with project members to develop models for software compatibility and solvers that can automatically integrate packages/components in complex codes.
- Participate in the establishment of future research directions and contribute to group grant proposals, including proposal presentations and preparation of proposals.
- Document complex research and development progress via technical reports, journal publications, and conference presentations and collaborate with a broad spectrum of scientists internally and externally to accomplish research goals.
- Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally to define and carry out the research.
- Perform other duties as assigned.

Qualifications
- Ph.D. in Computer Science, or a related field.
- Experience with aspects of the software production process such as compilation, build, dependency management, or packages and their relationships.
- Experience developing software in a high-level language such as C/C++, Python, Rust, or Julia.
- Experience with binary analysis, binary formats, and/or ABI compatibility issues.
- Knowledge of shared libraries, linkers, loaders, and low-level Linux runtime libraries (e.g., glibc, ld.so, compiler runtime libraries like libstdc++ or OpenMP implementations).
- Ability to conduct high quality independent research and to develop implementations to evaluate the results.
- Proficient verbal and written communication skills necessary to interact in a clear and concise manner, author technical and scientific reports and papers, and deliver scientific presentations.
- Initiative and interpersonal communication skills necessary to work effectively in a dynamic team environment.

Desired Qualifications
- Experience with SAT, SMT, ASP, or related combinatorial solvers.
- Knowledge of the internals of package management systems (e.g., rpm, apt, pip, cargo, conda, spack, pip, npm).

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  None required.

However, if your assignment is longer than 179 days cumulatively within a calendar year, you must go through the Personal Identity Verification process.  This process includes completing an online background investigation form and receiving approval of the background check.  (This process does not apply to foreign nationals.)

For additional information, please see DOE Order 472.2

 

Note:   This is a one year Postdoctoral appointment with the possibility of extension to a maximum of three years.  Eligible candidates are those who have been awarded a PhD at time of hire date.
