AirSage Inc., has been in the business of processing Big Data since before the term was widely understood. We’ve always had to contend with billions of daily records and we have evolved from custom filesystem based queuing systems and manually partitioned compute clusters to using the current state of the art Big Data workhorses. Our latest systems have been built on Kafka, Cassandra, Accumulo and Spark on Yarn. We are moving to a hybrid infrastructure model with web APIs and customer portals on the cloud while keeping the core of our compute capacity on premises. We’re looking for a motivated, capable and dynamic Junior Software Developer who wants to work side by side with seasoned professionals while learning the ins and outs of some of the most valuable technologies today. Our main two languages are Scala and Python but we have legacy systems implemented in Java and C++ stitched together by a healthy dose of bash scripting.

The Junior Software Developer is expected to follow the guidance of our senior team members while actively collaborating in the creation and maintenance of Spark on Yarn data flows performing data transformation, analytics and geospatial joins on billions of records every day as well as the web apps build for our Ops team to operate and monitor our internal and external systems.
