Ruby on Rails developers at Leadfeeder work mainly on our backends: building APIs, background data processing flows, and integrations. Being a very data-intensive application, much of the work on the Leadfeeder backend involves optimising and effectively using various databases – Cassandra, AWS RDS & Aurora, Elasticsearch and Redis, to name a few.
Our backend, we run multiple small-to-medium-sized Ruby on Rails apps and use serverless components (AWS Lambda, API Gateway, Kinesis) on the side. We pride ourselves on keeping apps working smoothly, and the codebase tidy and well-tested. We dedicate time for upgrades, refactoring and improvements in the developer experience.

Our hiring process:
After we’ve received and reviewed your application, there are a number of stages in our process.
- Initial video call. You’ll get to learn more about the role and our company, and we’ll learn how you communicate and what are you looking for in the job.
- Technical interview. Qualified candidates proceed to our technical interview, where we ask more in-depth technical questions.
- Home assignment. We’ll test your coding skills in building a small application. You can do this at home on your own time. The assignments usually take about 4-6 hours to complete.

This interview also includes some pair-programming, where we do some improvements or additional features to your project.

All interviews are done remotely over video calls, but of course, if you happen to be in the same city with some of our team members we’re happy to organize a meeting on site.
