Senior Ruby on Rails Engineer

Leadfeeder is a fast growing international SaaS startup, headquartered in Helsinki. We are on a mission to bring web intelligence into business. Leadfeeder helps over 4000 paying customers to identify who visits their website, qualify the leads based on their behaviour, and convert the most promising visitors into sales leads.

Currently, Leadfeeder is a buzzing remote international team of 80+ people and more than ten nationalities. We have a strong data-driven and customer-centric culture, and we pride ourselves on our sustainable growth, ambition and resilience.

Our 30+ strong in-house, all-remote engineering team is responsible for developing new features, and otherwise improving and maintaining the Leadfeeder product.

We are organised in feature-oriented, cross-functional squads. Each squad is responsible for specific features of the product, and works tightly together with high autonomy. Depending on the product area, squads are composed of Backend and Frontend Engineers, Designers, and are always paired with a Product Manager. We believe in listening to everyone's ideas and feedback – no matter what your role is, you get to have a say in the product and technical decisions of your squad.

About this job Ruby on Rails engineers 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 backend involves optimising and effectively using various databases – Cassandra, AWS RDS & Aurora, Elasticsearch and Redis, to name a few.

Our backend consists of multiple small-to-medium-sized Ruby on Rails apps and uses 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 overall improvements for developer productivity and happiness.

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.
