Job Description

Lynker Corporation is seeking a local Scientific Developer (DC Metro area) to support the National Weather Service Office of Modeling and Development (OMD). This hybrid role focuses on advancing UFS infrastructure for next-generation in-core data assimilation, including state management and rewind, automated testing, and coupling build enablement.

Responsibilities

Lead development of new UFS Weather Model infrastructure features that support next-generation forecasting capabilities, including in-core data assimilation (DA) and high-resolution moving nests.
Implement robust state management, including saving and advertising states to the NUOPC coupler, plus rewind capabilities that enable restarts from prior states without numerical drift.
Extend coupling support using the Earth System Modeling Framework (ESMF).
Design and implement automated tests to maintain the stability and robustness of state management and rewind as additional UFS Weather Model changes are introduced.
Partner with DA teams to enable UFS and JEDI builds with in-core DA capabilities.
Investigate and develop incorporation of incremental analysis updates (IAU) after the rewind step.
Use modern software engineering tools, including AI-assisted coding technologies, to accelerate delivery of high-quality infrastructure and comprehensive testing strategies.
Apply modern software development and management practices such as Git-based code management, unit testing, continuous integration, and Agile/DevOps techniques.
Debug complex model infrastructure and integration issues as they arise, including build failures, runtime errors, and coupled system bugs.
Maintain clear, high-quality documentation to support NWS developers.

Requirements

Background in computer science, software engineering, meteorology/NWP, applied mathematics, or a closely related field, with demonstrated numerical modeling and scientific computing experience.
Demonstrated experience with Earth system coupled modeling frameworks and infrastructure.
Expertise with ESMF and NUOPC is strongly preferred.
Familiarity with the UFS Weather Model and the Model for Prediction Across Scales (MPAS) is highly beneficial.
Expertise in modern Fortran and/or C, along with Python.
C++ proficiency is a strong plus, especially related to data assimilation frameworks such as JEDI.
Ability to develop and debug software on Linux or similar environments, including shell scripting or automation.
Strong preference for experience with data assimilation systems (especially JEDI) and initialization techniques such as IAU.
Working knowledge of modern software engineering practices including Git-based collaboration, continuous integration, testing, and documentation.
Familiarity with AI-assisted code development for high-quality, performant code, or strong willingness to learn.
Demonstrated experience running Earth system models on HPC platforms, including MPI distributed-memory parallelization and job schedulers such as SLURM or PBS.
Familiarity with cross-platform package management and build/test systems, particularly CMake and CTest.
Good verbal and written communication skills in English.
Ability to work effectively in a diverse, customer-focused team and collaborate with software engineers and scientists across agencies.
Self-starter approach to independently identify, prioritize, and execute development needs.
Experience in Agile/Scrum environments is preferred.
Candidates must be a U.S. Citizen or Green Card Holder.
