Two Sigma

Project: Internships in Big Data and Object Storage
Location: New York, NY
Summer 2017


Two Sigma is looking for interns for 2017 again from PDL, and we are starting our interviewing earlier this year. We have a new roster of projects planned for summer 2017, some are subject to change of course. In many cases there are opportunities to open source and/or publish the summer’s work.

Examples of the projects we have planned for 2017 are:

Big data financial time series optimization - Two Sigma builds storage systems for 10’s of petabytes of time series data. We are seeking a very highly capable summer intern familiar with low-level performance optimization and/or columnar file serializations to broaden our investigations in performance, space, and capability optimization for the data at rest and in our database systems.

Object storage metadata optimization - Our mission critical object storage systems provide strong guarantees for other engineering teams at Two Sigma. We have room for improvement on the latency of our metadata systems that manage this many 10’s of petabytes system. We are seeking a very highly capable summer intern familiar with high-performance distributed systems.

An example of a past summer project, of which there are more in the pipeline for 2017: Chronos Open Source Development - Chronos is an open source project maintained by Mesosphere, but we plan to add some additional capabilities to it that it does not currently support. The project would include working with Mesosphere and members of the Application Infrastructure team to build in new capabilities such as changes to make Chronos scale to the numbers of jobs we want to eventually support, or to handle failover across different Mesos clusters and different data centers. The final result of the project would be new features of Chronos that we contribute back to the open source project.
