This position will focus on enhancing coupled ocean and sea ice JEDI-based data assimilation system for the Global Forecasting System (GFS) by integrating critical marine observations. This may include transition from retrieved products to direct assimilation of Level 1b radiances for sea-surface-sensitive channels to improve atmosphere-ocean balance and sea surface temperature conditions, and integrating sea ice freeboard observations to address model biases and significantly improve sea-ice forecast skill., Designs and executes scientific projects of significant complexity, advancing understanding in theoretical, observational, and/or applied domains. Manages technical direction for projects, contributes findings in a variety of ways, and supports institutional and sponsor engagement. Provides mentorship, enhances research quality, and plays a part in shaping team and program outcomes. Engages in mission-aligned activities both within the organization and throughout the broader scientific community. Contributes through a combination of scientific expertise, professional service, and education and outreach efforts., * Designing and executing complex scientific and/or technical investigations, to address complex, often interdisciplinary problems. * Developing or refining scientific models, algorithms, experimental methods, observational techniques, or analytical tools, applying advanced technical principles and incorporating recent developments in the field. * Leading or coordinating scientific components of projects or programs, including establishing goals, methodologies, timelines, and overseeing deliverables across internal and external collaborators. * Applying advanced data analysis and interpretation techniques, including statistical, computational, or simulation-based approaches to extract insights and validate results. * Contributing to and/or co-leading peer-reviewed publications, technical reports, data sets, findings, proposals, and documentation, and presenting findings at national and international conferences, workshops, and stakeholder briefings. * Supporting less experienced staff and team members by providing technical guidance, fostering scientific growth, and supporting collaborative working environments. * Contributing to scientific proposal development and strategic planning. * Engaging with internal and external stakeholders, translating complex scientific findings for diverse audiences and helping to shape project direction or programmatic priorities. * Leading development of products, tools, instruments and/or technologies for projects and programs., Work may be performed in a combination of office, laboratory, industrial, and research environments depending on project assignments. Office-based work typically involves maintaining concentration and focus on assigned tasks, extended periods of computer use, prolonged periods of sitting or standing, reviewing information on screens or documents, applying established protocols in a timely manner, communication with others regarding project assignments, and participating in meetings or collaborative activities. This role and assigned projects may also include laboratory or field research activities that involve travel, work in variable environmental conditions such as weather and altitude (including extreme temperature changes, heat exposure, cold exposure, and other exposure to severe weather), and the use of specialized scientific instrumentation or equipment. Field assignments may occur in remote locations and may involve navigating uneven terrain, accessing elevated platforms, performing high-intensity manual tasks, or positioning oneself in constrictive spaces such as vehicles or aircraft. Work may involve interaction with hazardous equipment and processes including electrical systems, heavy machinery, or chemicals that may lead to exposure to irritants or pollutants. Participation in workplace safety training is mandatory, and the use of personal protective equipment (PPE) may be required depending on the assignment. Staff assigned to this role are expected to follow all applicable safety policies and procedures and must not pose a threat to the safety or wellbeing of themselves or others. Employees must be able to perform all mental and physical requirements necessary to carry out the responsibilities of the position and project assignments as outlined in the job description, which are considered essential functions of this position. All essential functions of the position must be performed with or without reasonable accommodation., * Validation and Impact Assessment: Conducting rigorous validation of the global data assimilation system through an iterative process. This includes analyzing model output, and evaluating the impact of assimilation techniques on model biases to drive system improvements. * System Configuration and Iterative Development: Developing and configuring the JEDI system for coupled data assimilation with GFS. This involves an iterative cycle of adding new observations to the data assimilation system (e.g., direct radiance assimilation for sea surface temperature, sea ice freeboard) and refining the system based on ongoing performance feedback. * Documentation and Stakeholder Coordination: Documenting research findings and coordinating with stakeholders at NWS/OMD and partner agencies to ensure the new capabilities are ready for operational integration into the GFS system. ## Related Videos - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Tackling the Risks of AI - With AI](https://www.wearedevelopers.com/videos/1690-tackling-the-risks-of-ai-with-ai) - [Introduction to TXT](https://www.wearedevelopers.com/videos/30-introduction-to-txt) - [Data Science on Software Data](https://www.wearedevelopers.com/videos/162-data-science-on-software-data) - [Empowering Retail Through Applied Machine Learning](https://www.wearedevelopers.com/videos/976-empowering-retail-through-applied-machine-learning) - [Implementing continuous delivery in a data processing pipeline](https://www.wearedevelopers.com/videos/73-implementing-continuous-delivery-in-a-data-processing-pipeline) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Data Analyst Salary in the UK](https://www.wearedevelopers.com/magazine/278-data-analyst-salary-in-the-uk) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Everything a Developer Needs to Know About MCP with Neo4j](https://www.wearedevelopers.com/magazine/604-everything-a-developer-needs-to-know-about-mcp-with-neo4j) - [Data Analyst Salary Austria](https://www.wearedevelopers.com/magazine/275-data-analyst-salary-austria)
