Middle Ruby on Rails Developer (I)

We’re looking for Middle Ruby on Rails Developer with a passion for programming and for writing beautiful code. You will join a team of exceptional developers working in a fast-paced environment to deliver world-class software.

About the Customer:
The Customer is an educational technology company based in Salt Lake City, Utah. It is the developer and publisher of a web-based learning management system, and a massive open online course platform.

About the Project:
The Customer’s solution has a few services that exist outside the primary monolith, which provide additional functionality to Customer’s core product - the world's fastest growing learning management system. The Customer needs help in operating and maintaining these services. This means the Customer needs a team staffed who is capable of full ownership of key parts of his product. This means things like having an operational mindset that will strive to surpass the Customer’s SLAs of 99.9% uptime 24x7, keeping the bug count very low, and focussing on test automation and eliminating waste (either process or technical).

The services will be:
- an attendance tool enabling teachers to easily record attendance. This is a standard Ruby on Rails app with backbone JS (and some react) on the frontend. Backed by RDS (both MySQL and Postgres).
- an Alexa skills service. This is a light service written as a JavaScript lambda and an Express/Node server application backed by DynamoDB.
a document viewing and annotation service. This is made up of a couple services, a Node app and a conversion service (knight rider) written in Java. Backed by S3 and DynamoDB. It also uses SQS and has a small amount of Scala.
- LTI applications using Ruby and Rails. They are deployed on our platform infrastructure and leverage Postgres, ElastiCache, S3, etc.
a learning content package manager. This service is made up of a 3rd party service written in Java/JavaScript/MySQL. Hosted with EC2 and RDS. There's also a wrapper written in rails/js/postgres.
