About the Role
To help us bring AppTweak to the next level, you will work closely in a small a multi-skilled team responsible for part of the AppTweak tool and infrastructure
As a senior developer, we expect you to have a strong understanding of the current tech environment and help us make the right decisions by understanding business requirements and translating these into strong scalable systems.
Once the technical design is complete, we expect you to take part in the implementation with the rest of your team. Your focus will be to:
- Architecture and build scrapers and ETL pipelines that ingest the data that power AppTweak
- Architecture and build API's that make those data available
- Monitor and optimize our message queue systems
- Monitor and optimize our infrastructure.
Technologies we use
Our SAAS product is a Ruby on Rails application serving a React Single Page Application.
Our scrapers and crawlers get their tasks from SQS queues and store data in a mix of MySQL, Redshift, MongoDB, PgSQL, and Elasticsearch databases. They are built using the Ruby programming language (without Rails).
Our JSON REST API's are built in Ruby as well using the Sinatra lightweight framework. This (and the scrapers) is where we anticipate you'll be working most of the time.
We deploy code using Concourse as a CI/CD pipeline to build Docker images deployed on a Kubernetes cluster hosted on AWS.
We also have several Python services, mainly to run ML models developed by our data scientists.
We monitor everything using Prometheus and Grafana to visualize time series and metrics in an efficient manner.
We follow an agile development process inspired by SCRUM, but adapted to our needs.
