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 are seeking a Senior Software Developer to help expand and enhance the company's unique product offering using up to date Big Data technologies.

The Senior Software Developer is expected to have an active role in all stages of our application life cycle; from initial discussions regarding matching of capabilities and new business cases, through initial implementation, testing and validation to deployment and maintenance. The role requires working collaboratively across other functional areas outside of Software Development: IT, Data Services, and Operations.  This position reports to the Director of Research and Development.

  • Experience setting up autobuilds using Jenkins
  • Experience with git and understanding of multiple branching models (git flow in particular)
  • Very comfortable with the Linux command line and utilities; the ability to create launcher scripts will be highly valued; candidates who are very familiar with RedHat based Linux distributions and who are able to set up development servers and troubleshoot deployment issues will be preferred.
  • Exposed to deployment tools like Puppet, Chef or Ansible in production. Puppet is preferred but not required.

Other highly valued skills:

  • Experience with PostgreSQL and PostGIS
  • Experience setting up nginx as a web service/app proxy balancer and the use of uwsgi to deploy apps to it.
