Spire Global is a space-to-cloud analytics company that owns and operates the largest multi-purpose constellation of satellites. Its proprietary data and algorithms provide the most advanced maritime, aviation, and weather tracking in the world. In addition to its constellation, Spire’s data infrastructure includes a global ground station network and 24/7 operations that provide real-time global coverage of every point on Earth.
Spire Global is seeking a Statistical Data Scientist to contribute to the Company’s effort of developing its portfolio of machine learning and statistical post-processing models for supporting our weather applications. This is an exciting opportunity for motivated scientists to improve the weather forecast through state-of-the-art predictive modeling, machine learning, statistical models, time series analysis, and numerical optimization techniques using the available surface observations, numerical weather predictions models outputs, large amount of Radio Occultation (GNSS-RO), Reflectometry (GNSS-R) and other satellite data.
As a successful candidate, you will join the Statistics and Machine Learning group under the Global Validation Model branch, working with top-level scientists at Spire and around the world. Collaborating with teams such as software engineering, modeling and data assimilation, you will be a part of implementing and evaluating machine learning and statistical weather models and making use of large datasets of surface and satellite observations.
Responsibilities will include the following tasks:
Propose and implement innovative predictive modeling, machine learning and Bayesian inference approaches to increase the forecast skills of weather fields forecasts and distributions.
Develop and implement advanced quality control methods.
Develop and implement advanced sampling methods to address insufficient data sets.
Develop and implement state of the art weather post-processing techniques.
Explore different standard and non-standard data sources including Spire GNSS-RO and GNSS-R measurements, visible and IR satellite images from the GOES Advanced Baseline Imager, feature selection and sensitivity techniques to identify predictors for weather data driven models.
Working with meteorological data sets from various sources.
Working with the software engineering team to define most effective software solutions including transition to operations.
Presenting research findings at scientific conferences or workshops.
Applicants must have either a MS or PhD degree in Data Science, Computer Science, Applied Mathematics, or Atmospheric Science or equivalent working experience in machine learning algorithms and advanced statistical inference methods.
Working experience with linear/non-linear regression and classification methods and deep learning techniques including Generalized Linearized and Additive Models, Decision Trees, Clustering, Support Vector Machine, Neural Network, Multi-level models, Random Forests, Gaussian Processing, etc.
Working experience with time series analysis, recurrent and LSTM neural network.
Working experience with combining multiple models and ensembles for predictive modeling and uncertainty quantification (Mixture models for density estimations, Bayesian Modeling Averaging, Ensemble Model Output Statistics, etc.)
Working experience with statistical inference methods for uncertainty quantification such as Bayesian inference and Adaptive Metropolis algorithms.
Working experience with numerical optimization and automatic differentiation techniques.
Working knowledge of Python, Fortran, Matlab, Linux scripting and code management practices.
Prior experience working with meteorological or oceanographic datasets (GRIB and NetCDF formats) in distributed computing environments.
Experience with modern software engineering principles and best practices including DevOps environment.
Demonstration of enthusiasm and ability to work in a development team that never stops improving predicting modeling techniques, statistical and machine learning methods and their outcomes.
