About the job

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.

For people with skills and interest, we offer possibilities to work on our Ember.js frontend too, enabling people to grow to a fullstack role. Equally, there are opportunities to learn and be involved in infrastructure, DevOps and serverless development.

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.
  • Assignment review and skills interview. After our team has reviewed your assignment, we invite you to the next interview. We'll provide feedback and ask questions about your code. This interview also includes some pair-programming, where we do some improvements or additional features to your project.
  • Culture interview. The final step before decisions. Great cultural fit is highly important in our remote team. We also want to give you as much as possible information on how it is to work at Leadfeeder and what our culture is like.

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.
