AI and Data Assimilation Scientist

About the role

Lynker is seeking a talented and experienced AI and Data Assimilation Scientist to support the Environmental Modeling Center (EMC) within the National Centers for Environmental Prediction (NCEP). The primary objective of this role is to develop and transition innovative AI-based Data Assimilation (DA) systems.

Responsibilities

• Perform their job duties to a high standard, working both independently and collaboratively, focusing on scientific developments that advance the use of AI-DA techniques as an alternative to traditional ensemble/variational-based techniques.
• Lead the development, implementation, testing, and evaluation of an AI-based Real-Time Mesoscale Analysis (AI-RTMA) system in support of NOAA’s National Blend of Models (NBM).
• Conduct a comprehensive review of state-of-the-art AI-based data assimilation and end-to-end weather forecasting methodologies, systems, and frameworks.
• Communicate findings with EMC scientists and external partners to inform the development of a scientifically robust and efficient AI-RTMA approach.
• Collaborate with NOAA’s NBM team and key stakeholders to define product requirements for AI-RTMA, including domain configuration, grid structure, output variables, spatial and temporal resolution, and data formats suitable for operational evaluation and transition.
• Design, implement, and maintain robust data pipelines to support AI-RTMA training, validation, testing, and evaluation.
• Develop, train, rigorously test, and deploy a fully functional AI-RTMA system based on selected AI frameworks or architectures.
• Implement cross-validation and other evaluation methodologies to quantify model performance and reliability during inference.

Requirements

• Experience developing, training and deploying AI-based systems applied to geophysical systems.
• Experience with common AI frameworks such as PyTorch, TensorFlow.
• Experience working with earth observation data, including conventional observations, satellite, radar.
• In-depth knowledge of data assimilation techniques (observation forward modeling, quality control, variational-based and/or ensemble methods).
• Strong foundation in the physical, statistical and mathematical basis of geophysical modeling (atmospheric and/or environmental).
• Excellent Python programming skills.
• Practical experience utilizing High Performance Computers (HPCs) and GPUs.
• Proven experience working in a UNIX environment with advanced scripting languages.
• Good communication skills, both oral and written, in English.

Qualifications

• Experience with cloud platforms and use of IDEs for development.
• Experience with cloud-native data formats such as Zarr, Parquet.
• Experience with compiled languages.
• Comfort using agentic AI tools to accelerate development.
• Experience executing numerical models on HPC platforms using parallelization frameworks and job scheduling systems.
• Familiarity with coupled earth system models.
• Knowledge of modern software engineering practices (requirements gathering, design, prototyping, version control, integration, testing, and documentation).
• Prior experience in model testing, evaluation, or knowledge of verification principles.
