Software Engineer, Data

Job Stack: Python, Numpy/Pandas
Terality's stack: Python/Rust, AWS, GitLab...

With Adrien, our co-founder and CTO, you will be working on Terality's core product: our proprietary distributed pandas engine, which allows our users to run pandas code in a few seconds, even on TB of data, by just changing their import line. Your main first mission will be to implement parallelized versions of functions from the pandas API. Your code will be shipped to production asap. You'll have a direct and immediate impact on Terality's users.

Secondary tasks will include:
- Optimizing our data representation and storage using the bleeding edge data formats (Parquet/Arrow/Feather v2...)
- Improving the design of our internal API and networking (REST/gRPC, http/websockets...)
- Refining the user's experience using Python's hacking tricks and advanced dynamic features up to the point it will look like black magic (advanced Python)
- Increasing the performance of our scheduler to better distribute our workloads (parallel computing, asynchronous computing, DAG...)

Joining us will make you an expert at advanced data processing!
