As a Ruby Developer, you’ll be responsible for writing clean, modern code that adheres to best practices. We’re looking for a self-motivated individual who takes pride in their work, values high-quality code, and cares deeply about the overall application experience.
We pride ourselves on having very high test coverage and rarely having any prod issues. Our backend follows a microservices architecture, consisting of multiple small services—primarily built with Ruby—that collectively power the user experience.
This role may have on-call responsibilities.

REQUIREMENTS:

• 5+ years of experience with Ruby (bonus points for React)
• Strong knowledge of SQL databases, query optimizations
• Excellent problem-solving and debugging skills
• Experience with RESTful APIs, microservices, and third-party integrations
• Knowledge of background job processing tools (Sidekiq, etc.)
• Proficiency in at least 2 programming languages
• Good written and verbal communication skills in English
  Don’t ‘tick all of the boxes? Neither do we. We are driven by hiring not only by experience and relevance for the role but also by ambition. We celebrate anything ‘outside of the box’, so if you don’t meet all of the listed tickbox criteria, please do still apply as we’d love to hear from you.
