The Role:
We are looking for a Senior Fullstack Ruby on Rails Developer 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.
What we are looking for:
- 5+ years of production experience building and scaling applications using Ruby on Rails (Rails 6/7) and modern Ruby 3.x features.
- 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.
- Deep knowledge of PostgreSQL or MySQL, specifically in writing complex ActiveRecord queries, optimizing indexes, and managing database migrations safely at scale.
- Extensive experience managing background jobs, race conditions, and heavy data processing using Sidekiq and Redis.
- A strict habit of writing maintainable test suites using RSpec, Capybara, or FactoryBot to ensure high test coverage and stable deployments.
- Proven track record of designing, securing, and documenting clean RESTful APIs.
- Solid understanding of Git workflows, Docker containerization, and asset compilation pipelines (Propshaft, Webpacker, or Vite Ruby).
Nice-to-Have:
- Experience migrating legacy Rails applications to newer versions.
- Familiarity with cloud platforms (AWS, Heroku, or Render) and CI/CD pipelines.
- Understanding of domain-driven patterns within Rails to keep large codebases decoupled.
- Knowledge of web security best practices (OWASP Top 10, cross-site scripting prevention).
Responsibilities:
- Design, architect, and implement clean, test-driven features across both the backend and frontend layers.
- Profile and optimize slow queries, eliminate N+1 query bugs, and optimize frontend rendering paths to keep application response times low.
- Participate in rigorous peer code reviews, championing idiomatic Ruby patterns, security protocols, and robust architectural choices.
- Act as a technical sounding board for Product and Design teams, helping evaluate the technical feasibility of upcoming features.
- Assist in maintaining and improving deployment workflows to ensure reliable, zero-downtime releases.
What we offer:
Get paid, not played
No more unreliable clients. Enjoy on-time monthly payments with flexible withdrawal options.
Predictable project hours
Enjoy a harmonious work-life balance with consistent 8-hour working days with clients.
Flex days, so you can recharge
