Senior Ruby on Rails Developer

Ruby engineers at Sensor Tower apply their creativity and backend experience to create meaningful, actionable data products and insights about mobile apps.

This role focuses on designing, implementing, and optimizing performant and scalable solutions to manage our high volume data pipelines. As our data is central to the Sensor Tower product, this is a high impact role. Backend Ruby developers at Sensor Tower serve as force multipliers for all of our engineering teams by ensuring easy access to data for all, scaling our system to enable the development of more sophisticated features, and implementing widely used tooling.

Recent examples of such impactful projects include:
- ~10x scaling of data science processing jobs, enabling us to generate more granular mobile app analytics breakdowns
- Migrating high volume data from MongoDB to ClickHouse for blazing fast, simpler, more generalizable querying
- Designing an ETL pipeline to provide easy-to-ingest data (for both customers and internal analysts) backed in Snowflake
- Managing actionable events and notifications driven by newly ingested data

We are a fully distributed, remote first company.

  • Develop and optimize high performance data aggregation and analysis pipelines in Sidekiq at scale (1,000+ concurrent worker instances)
  • Scale our system to simply and efficiently process even higher volumes of data
  • Accelerate the development of other engineers by providing easy access to data and internal developer tooling
  • Fully own your work through the development lifecycle of our core platform, including design, implementation, quality, release, and monitoring

Experience We Want To See
  • You’re an experienced software developer who has paid, professional experience shipping software to customers 
  • You have a high degree of proficiency working in Ruby on Rails
  • You enjoy working on complex, data driven projects and have worked with MongoDB (or other NoSQL DBs) and preferably ClickHouse, Druid, Pinot or similar OLAP databases
  • Strong foundation in applying your programming, algorithms, and software application design skillset to build performant systems
  • Exposure to working with databases, data pipelines and distributed data at scale
