Senior Ruby on Rails Engineer

Feb. 17, 2021

As a Senior Ruby on Rails Engineer, you will work on our very ambitious e-commerce ventures on a solid and fresh codebase. Your job is to maintain and extend what we already have, come up with ideas to improve scalability, performance, security, and usability, keep up with the new versions of the framework, libraries, and tools. You will work with teams spread across 3 continents and will think about initiatives to make us more productive in extending our new product suites or building new ones. Our environment is low on processes and meetings with a strong emphasis on best practices and code quality. We have loosely defined teams of people who put a high value on personal autonomy. If this sounds tempting to you and you think you are a good fit, we would love to hear from you!

Skills & Requirements

Experience and Pragmatism

This role is for somebody who has been through several releases and products built from the ground up. We expect some degree of specialization on technology but if that does not align with the one we’re using at the moment we don’t mind.

What we expect is:

  • University Degree in CS, CE or closely related

  • At least 5 years of experience writing code professionally for the Web

  • Proficiency with Ruby on Rails (2+ years of experience preferred)

  • A good understanding of all common data structures

  • Ability to write complex algorithms

  • Ability to design software systems with multiple parts across multiple technologies

  • A good understanding of performance optimization techniques

  • Ability and drive to deliver high-quality code at a consistent pace

What is it like to work for us?

Here are some principles we have that might help you figure that out:

  • Offering the best and expecting to get the same in return: you choose your hardware to work on, we buy top-of-the-line chairs and standing desks; once the pandemic is over, you'll enjoy working from a great office with quiet working spaces and nice recreation areas

  • Autonomy: you will be in the driver seat when it comes to proposing technical solutions to the problems you solve

  • Mastery: we will encourage and support you to learn as long as it takes so you can feel proud about your work (the nice side effect of this is having awesome products built by you)

  • Low on processes: we rely a lot on personal decisions instead of guiding behavior through processes. No mandatory regular meetings. No standups.


  • Top market salary

  • Medical subscription (top tier at Regina Maria)

  • 26 paid vacation days

  • Other small perks some more regular and predictable than others
