&nbsp;
The Role:
&nbsp;
We are looking for a&nbsp;Senior Fullstack Ruby on Rails Developer&nbsp;to join one of our high-growth client teams. In this role, you will be a key driver of the application's lifecycle, writing clean, idiomatic Ruby code to build robust backend features while ensuring a smooth, highly interactive frontend user experience.
You will help the client leverage the "Rails way" to ship features quickly, without sacrificing long-term maintainability, testability, or performance. This is an ideal position for a developer who appreciates the elegant architecture of Rails but understands how to optimize database queries, scale background workers, and deliver a modern interface.
&nbsp;
&nbsp;
What we are looking for:
<ul>
<li>5+ years of production experience building and scaling applications using Ruby on Rails (Rails 6/7) and modern Ruby 3.x features.</li>
<li>Strong proficiency with frontend assets in Rails. This includes deep experience with Hotwire (Turbo/Stimulus) OR modern SPA frameworks like React.js or Vue.js connected via a Rails API.</li>
<li>Deep knowledge of PostgreSQL or MySQL, specifically in writing complex ActiveRecord queries, optimizing indexes, and managing database migrations safely at scale.</li>
<li>Extensive experience managing background jobs, race conditions, and heavy data processing using Sidekiq and Redis.</li>
<li>A strict habit of writing maintainable test suites using RSpec, Capybara, or FactoryBot to ensure high test coverage and stable deployments.</li>
<li>Proven track record of designing, securing, and documenting clean RESTful APIs.</li>
<li>Solid understanding of Git workflows, Docker containerization, and asset compilation pipelines (Propshaft, Webpacker, or Vite Ruby).</li>
</ul>
&nbsp;
&nbsp;
Nice-to-Have:
<ul>
<li>Experience migrating legacy Rails applications to newer versions.</li>
<li>Familiarity with cloud platforms (AWS, Heroku, or Render) and CI/CD pipelines.</li>
<li>Understanding of domain-driven patterns within Rails to keep large codebases decoupled.</li>
<li>Knowledge of web security best practices (OWASP Top 10, cross-site scripting prevention).</li>
</ul>
&nbsp;
&nbsp;
Responsibilities:
<ul>
<li>Design, architect, and implement clean, test-driven features across both the backend and frontend layers.</li>
