This is a full-stack role in a startup at exiting and busy times. You must be comfortable working with various programming languages and infrastructure as well. One week you might guide our data scientists how to write Python lambdas and another week debugging Node.js lambdas. Our backend is in Elixir and Ruby and running on AWS(we use lambdas, ddb, kinesis, sqs, iot...) and Heroku (we will be migrating all to AWS).
