Research Software Engineers

Pasadena, CA

We are seeking research software engineers to implement and integrate components of the first Earth system model (ESM) that automatically learns from global observations and targeted high-resolution simulations of clouds, turbulence, and other elements of the Earth system. As a CliMA research software engineer at Caltech, you will collaborate with a dynamic, multi-disciplinary team of curious and creative scientists, engineers, and applied mathematicians, spanning Caltech, NASA’s Jet Propulsion Laboratory, the Massachusetts Institute of Technology, and the Naval Postgraduate School.

You will 

  • Work on an ambitious, high-profile scientific project with an opportunity to impact Earth system modeling worldwide;
  • Contribute to the design and early-stage development of high performance software architecture suitable for the next generation of supercomputing hardware;
  • Work alongside and develop connections with experts in GPU programming, language design, compiler development, parallel high performance computing, and numerical techniques;
  • Write open source software using a modern language and development techniques to ensure code health, scalability, and robustness; and
  • Work in a friendly and diverse working environment, collaborating closely with researchers in climate science, machine learning and applied mathematics.

As minimum qualification, you are expected to have

  • Completed a BS degree in computer science or a science/engineering field;
  • Experience developing large software projects in a distributed fashion, e.g., contributing to an open source project with distributed contributors; and
  • Experience with at least two programming languages (e.g., C, C++, Fortran, C#, Objective C, Python, Julia, Matlab/Octave).

Beneficial additional experience includes

  • A graduate degree in computer science or a science or engineering field;
  • Experience working with high-performance computing systems, including multicore processors and GPU or other accelerators;
  • Experience in either physics, computational fluid dynamics, or machine learning; and
  • Experience working in multi-disciplinary teams and interacting cross-functionally with a wide variety of people.

We are seeking to fill several software engineering positions within CliMA.

Research Scientists

Pasadena, CA

We are seeking research scientists to develop, test, and implement components of the first Earth system model (ESM) that automatically learns from global observations and targeted high-resolution simulations of clouds, turbulence, and other elements of the Earth system. As a CliMA research scientist at Caltech, you will collaborate with a dynamic, multi-disciplinary team of curious and creative scientists, engineers, and applied mathematicians, spanning Caltech, NASA’s Jet Propulsion Laboratory, the Massachusetts Institute of Technology, and the Naval Postgraduate School.

You will advance the state of knowledge and contribute to the development of a data-informed ESM in one or more of several possible ways:

  • Devising fast and scalable data assimilation and machine learning (DA/ML) algorithms that allow a computationally complex ESM to learn from diverse data sources, such as satellite observations or high-resolution simulations of turbulent flows;
  • Developing physically informed parameterizations of subgrid-scale processes in the atmosphere that are suitable for DA/ML approaches, including models for boundary layer turbulence, clouds, and convection;
  • Developing components of a land hydrology and biosphere model that uses DA/ML algorithms to learn from space-based observations of the hydrologic cycle and of the biosphere; or
  • Prototyping and building capabilities to run high-resolution large-eddy simulations on demand within a global ESM.

We are seeking to fill several research scientist positions, spanning a range of expertise from computational and applied mathematics to the atmospheric and oceanic sciences.

As minimum qualification, you are expected to have

  • Completed a doctoral degree in applied mathematics, atmospheric or oceanic sciences, computer science, engineering, physics, statistics or a related field at the time of the appointment;
  • A strong physical, mathematical, and/or computational background;
  • Programming experience in at least one general purpose language;
  • Demonstrated effective written and verbal communication skills;
  • At least 2 years of postdoctoral experience;
  • Leadership experience of research projects, as demonstrated by publications.

We prefer for you to have

  • Experience with high-performance parallel computing;
  • Experience working in multi-disciplinary teams and interacting cross-functionally with a wide variety of people.
