Description

At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.

Northrop Grumman Mission Systems is a trusted provider of mission-enabling solutions for global security. Our Engineering and Sciences (E&S) organization pushes the boundaries of innovation, redefines engineering capabilities, and drives advances in various sciences. Our team is chartered with providing the skills, innovative technologies to develop, design, produce and sustain optimized product lines across the sector while providing a decisive advantage to the warfighter. Come be a part of our mission!

We are seeking Computational Scientists with a robust scientific and computational background who have the skills and interest in developing and implementing scalable scientific software and algorithms used to model physical processes on high-performance computing (HPC) systems. This position will involve code optimization and algorithm development towards improving existing software and tools as well as developing new efficient ones.

This position requires full-time work on site at our Linthicum, MD facility or our Annapolis Junction, MD facility.

Your responsibilities:

  • Benchmark and profile existing codes and workflows; identify bottlenecks and throughput limitations and establish path for improvement.
  • Enable scaling of simulation and optimization software on HPC systems through the design and development of efficient serial and parallel algorithms.
  • Develop and implement numerical simulation models and scientific algorithms for modeling physical processes of interest.
  • Improve simulation performance via hardware-aware code optimization at the core, node, and system (internode) level.
  • Develop, improve, and orchestrate complex HPC workflows that use off-the-shelf and custom modeling tools for efficient execution on HPC systems.
  • Benchmark and profile new codes and workflows and report on improvements.

This position can be filled at the Principal OR Sr. Principal level. Qualifications for both positions are listed below:

Basic Qualifications for Principal Computational Scientist:

  • Bachelor’s degree in applied mathematics, computational chemistry, computer science, physics or a relevant STEM field with 5 years of relevant technical experience; Master's degree in applied mathematics, computational chemistry, computer science, physics or a relevant STEM field with 3 years of relevant technical experience OR Master’s degree in applied mathematics, computational chemistry, computer science, physics or a relevant STEM field and currently enrolled in a PhD program with a completion date prior to start with 1 year of relevant technical experience; PhD in computational chemistry, applied mathematics, computer science, physics or relevant STEM field with 1 year of relevant technical experience.
  • Experience with developing physics-based simulation and scientific software.
  • Domain expertise in at least one scientific field (e.g., condensed matter physics, quantum chemistry, fluid dynamics, solid mechanics, or any other field where computational methods are used for predictions).
  • Experience with collaborative scientific software development (e.g., Git).
  • Familiarity with code optimization and HPC hardware.
  • Proficiency in writing code in C or C++ (preferred) and Python.
  • This position requires the applicant to be a U.S. Citizen.
  • Ability to obtain and maintain a U.S. Government security clearance per business requirements.

Basic Qualifications for Sr. Principal Computational Scientist:

  • Bachelor’s Degree in applied mathematics, computational chemistry, computer science, physics or a relevant STEM field with 8 plus years of relevant technical experience; Master’s Degree in applied mathematics, computational chemistry, computer science, physics or a rel
