About us

Leadfeeder is a fast-growing international SaaS startup, headquartered in Helsinki, Finland. We are an international remote team of 80+ members from around the world.

We've developed an online service which automates sales lead generation for B2B companies. Leadfeeder helps over 3000 paying customers to identify who visits their website, qualify the leads based on their behaviour, and convert the most promising visitors into sales leads.

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 comprised 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 full-stack role. Equally, there are opportunities to learn and be involved in infrastructure, DevOps and serverless development.
