Meteorological Scientist - Data Assimilation and NWP

Meteorological Scientist - Data Assimilation and NWP WindBorne Systems is supercharging weather forecasts with a unique proprietary data source: the largest balloon constellation in the world. WindBorne Atlas is backed by next-generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence. Our mission is to eliminate weather uncertainty, and in the process help humanity adapt to climate change, be that predicting hurricanes or speeding the adoption of renewables. We are building a future in which the planet is instrumented by thousands of our microballoons, eliminating gaps in our understanding of the planet and giving people and businesses the information they need to make critical decisions. The founding team of Stanford engineers was named Forbes 2019 30 under 30 and is backed by top-tier investors, including Khosla Ventures and Footwork VC. WindBorne is seeking a Meteorological Scientist to contribute to the improvement of weather forecasting and observational analyses. As a member of the weather team, you’ll incorporate WindBorne's unique state-of-the-art balloon constellation observations into the most advanced weather prediction systems. You’ll work with our team of scientists, engineers and flight controllers to influence the collection and use of observations from start to finish, beginning with balloon flight and ending with insights to help consumers, businesses and governments adapt to changing weather and climate.
