Job Description

LeapYear's secure machine learning platform is deployed by some of the largest enterprises in the world across finance, healthcare, and technology.
Our technology ensures differential privacy, a widely recognized standard of data privacy that enables all data - including sensitive information - to be utilized for analytics, while providing mathematically proven privacy protection.
The LeapYear system is composed of a core set of components that allow private machine learning on data sets that can scale to petabytes. The system includes private algorithms for relational operations, statistical methods and machine learning. A data scientist accesses private data using a Python API. Administration is provided  via a web-based GUI or an API.
LeapYear's platform team builds the services that allow our product to integrate with complex enterprise environments and operate effectively on our customers’ most sensitive data.
The platform includes services for authentication, access control, logging, auditing  and support for integration of data from a variety of data sources including SQL/NoSQL Databases, HDFS and S3. Queries are processed using Spark to support to enable fast, distributed processing  of massive data sets. The services are primarily written in Haskell, with Python, Scala, and Java used as additional supporting languages.
We are looking for platform engineers that have a track record of developing enterprise-ready features for technical end users, including enterprise integrations, rigorous security, flexible deployment, and support for diverse data sources.
Recent technical challenges we've been working on
