Job Description

About the Role

As a Senior Fullstack Ruby on Rails Developer, you will play a crucial role in driving the application's lifecycle for one of Proxify's high-growth client teams. Your primary responsibility will be to design, architect, and implement clean, test-driven features across both the backend and frontend layers. With a strong focus on coding excellence, you will work closely with the client team to leverage the 'Rails way' and deliver high-quality solutions.

The role entails collaborating with cross-functional teams, including Product and Design, to evaluate the technical feasibility of upcoming features and provide expert guidance on implementation. You will also participate in rigorous peer code reviews, championing idiomatic Ruby patterns, security protocols, and robust architectural choices.

Proxify's network of supportive and talented developers provides a unique opportunity for growth and learning. With a strong track record of connecting top developers with high-growth clients, Proxify offers a platform for professionals to showcase their skills and take their careers to the next level.

What You Will Do

  • 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
  • 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
  • Collaborate with cross-functional teams to deliver high-quality solutions
  • Write maintainable test suites using RSpec, Capybara, or FactoryBot to ensure high test coverage and stable deployments
  • Design, secure, and document clean RESTful APIs
  • Manage background jobs, race conditions, and heavy data processing using Sidekiq and Redis

What We Are Looking For

  • 5+ years of production experience building and scaling applications using Ruby on Rails (Rails 6/7) and modern Ruby
  • Strong proficiency with frontend assets in Rails, including Hotwire (Turbo/Stimulus) or modern SPA frameworks like React.js or Vue.js
  • 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)

Benefits and Perks

  • On-time monthly payments with flexible withdrawal options
  • Predictable project hours and a harmonious work-life balance with consistent 8-hour working days
  • Up to 24 flex days off per year without losing pay for full-time positions
  • Career-accelerating positions at cutting-edge companies
  • Hand-picked opportunities personally matched to your skills and interests
  • Access to a network of supportive and talented developers
  • Opportunities for growth and learning through collaboration with cross-functional teams

How to Stand Out

  • Ensure your portfolio showcases your expertise in Ruby on Rails development, with a focus on full-stack applications and complex backend features.
  • Highlight your experience with modern frontend frameworks like Hotwire, React.js, or Vue.js, and demonstrate your understanding of database management and optimization.
  • Prepare to discuss your approach to testing, debugging, and optimizing code, as well as your experience with agile development methodologies.
  • Familiarize yourself with Proxify's platform and network, and be prepared to discuss how you can leverage their resources to deliver high-quality solutions.
  • Be prepared to provide specific examples of your experience with Ruby on Rails, and demonstrate your ability to communicate technical concepts to non-technical stakeholders.
  • Research the company and the client team you will be working with, and be prepared to discuss how your skills and experience align with their needs and goals.
