Senior Software Engineer: Massive Graph Processing

LiveRamp is an Identity technology company based in downtown San Francisco. Our core product provides a privacy-friendly way to combine identifiers a company may have for a customer.

We on the Identity Engineering team maintain the graph processing engine that connects the billions of different identifiers for consumers and the devices they use online. Help us process this trillion edge graph as quickly and efficiently as possible.

You will get to work on projects such as:   

  • Pregel Path Computer: This system finds relevant graph paths using the pregel graph computation framework as implemented in Apache Giraph.
  • Edge Ingestion and Partitioning Framework: We could never process all trillion edges at once and luckily we don’t have to. Instead we process subgraphs that contain specific types of edges. Our edge ingestion and partitioning leverages LiveRamp’s Seek MSJ framework to efficiently incorporate new data into existing edge stores.
  • Path Computation as a Service: We provide a service to other LiveRamp engineering teams for finding specific types of paths within our massive graph. It handles 20,000 requests a day and this is possible due to its use of caching and intelligently batching similar request together.

Your Team:

  • We find feedback to be important in helping us grow as individuals and as a team; we’re always looking for chances to kindly share positive and constructive feedback and we aim to accept feedback with grace.
