Vistar Media | Full Time | Onsite (Philadelphia, PA)
We're an advertising tech company focusing on geotemporal data analysis. We'd love to hire engineers with experience in high-performance distributed server development or large-scale JS applications.

We're a mature startup with an established, well-tested codebase, but we aren't afraid to shake things up. We want to solve our problems with the right tools, whether they’re cutting-edge, or tried-and-true.
Some of those tools:
  Scala
  Python
  Go
  Spark
  CoffeeScript
  PostgreSQL / PostGIS
  EC2, SQS, DynamoDB
  React and Flux
  Flask

Some nice-to-haves:
  * Have coded a non-trivial system soup to nuts. CSS, persistence, deployment, et cetera
  * Understand Linux to a degree where you’d be comfortable admin’ing a fleet of boxes
  * Be able to design and implement a large, efficient codebase
  * Be able to ballpark the computational complexity of a snippet of code
  * Be able to both identify and implement a practical test suite
