Ruby on Rails Developer

Telecommute · Belgium expand job description ↓


If you’re any good at Ruby, the chance that you’re fiddling your thumbs at home, anxiously refreshing your inbox 20 times a minute hoping for a job offer, is rather slim. We know how it is.

Which is why we’ll try to sell ourselves to you here.

Ahum. Here it comes.

What makes the dev team at Silverfin special?

First of all, we build a hell of a product. Just to give you a sense of scale: our largest table has 3 billion rows. Mind you, we don’t just build Silverfin for the sake of it. Our product solves a very real problem: it automates and improves a large chunk of the repetitive tasks people working in financial services spend their time on.

Most of us work remotely. We’re based in Belgium, France, Estonia, Slovakia... Without Slack we’d be lonely, now we just zap in and out of the zone as we wish.

We’d be really happy to welcome you in our #dev channel. It’s not just virtual: we make sure we regularly get to see each other IRL too: twice a year we fly the team together in a different location across Europe.

What are we looking for?

We’re looking for somebody who’s really great at developing in Ruby, and in Ruby on Rails.

  • Experienced with Rails
