Company Description

Join us and make YOUR mark on the World!

Are you interested in joining some of the brightest talent in the world to strengthen the United States’ security? Come join Lawrence Livermore National Laboratory (LLNL) where our employees apply their expertise to create solutions for BIG ideas that make our world a better place.

We are looking for individuals that demonstrate an understanding of working in partnership with team peers, who engage, advocate, and contribute to building an inclusive culture, and provide expertise to solve challenging problems.

Job Description

We have an opening for a Computer Scientist 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.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

In this role you will

  • 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.
  • Perform other duties as assigned.

Additional responsibilities at the SES.3 Level

  • Lead multiple parallel tasks and priorities of customers and partners to ensure complex deadlines are met.
  • Responsible for various complex projects, coordinate team members’ skills to complete complex projects/tasks, and convert abstract/complex problems into useable algorithms/software modules.
  • Drive own research directions, propose and lead own research projects.


  • Ph.D. in Computer Science, or a related field or the equivalent combination of education and related experience.
  • 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,, 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.

Additional qualifications at the SES.3 Level

  • Significant experience with all aspects of the software production process and developing software.
  • Advanced analytical, problem-solving, and decision-making skills to develop creative solutions to complex problems.
  • Advanced verbal and written communication skills necessary to interact with a multi-disciplinary research team, author technical and scientific reports and papers, and deliver scientific presentations.
