• Integrate front-end frameworks (Stimulus, React, Vue) into Rails apps where required.

Database Management:

• Design, migrate, and maintain schemas in PostgreSQL or MySQL.
• Optimize queries for performance and scalability.
• Implement indexing, caching, and background jobs (Sidekiq, Resque).

Testing & Quality Assurance:

• Write and maintain unit, integration, and system tests (RSpec, Minitest, Capybara).
• Ensure CI/CD pipelines are configured for automated testing and deployment.
• Maintain ≥80% code coverage and enforce style/linting rules (RuboCop, StandardRB).

Security & Compliance:

• Implement user authentication/authorization (Devise, OmniAuth).
• Enforce security best practices (CSRF protection, input validation, OWASP).
• Ensure compliance with data privacy laws (GDPR, HIPAA as applicable).

Performance & Monitoring:

• Optimize page load times, API response times, and background job throughput.
• Monitor systems with tools like New Relic, Datadog, Honeybadger, or Rollbar.
• Troubleshoot issues and deploy hotfixes with minimal downtime.

Collaboration & Documentation:

• Work with product managers and designers to scope and prioritize features.
• Participate in sprint ceremonies and provide accurate story estimates.
• Document code, APIs, and workflows for long-term maintainability.

What Makes You a Perfect Fit:

• Deep knowledge of the Rails ecosystem and conventions.
• Strong problem-solver who can balance speed and scalability.
• Passion for clean, maintainable, and well-tested code.
• Effective communicator, comfortable collaborating across teams.

Required Experience & Skills (Minimum):

• 3+ years Ruby on Rails development experience.
• Proficiency in Ruby, Rails, ActiveRecord, and MVC architecture.
• Experience with PostgreSQL/MySQL and background job frameworks (Sidekiq, Resque).
• Familiarity with Git workflows and CI/CD tools.

Ideal Experience & Skills:

• Experience with front-end integration (Stimulus, React, Vue).
• Deployed Rails apps to Heroku, AWS, or GCP.
• Familiarity with caching (Redis, Memcached).
• Industry exposure in SaaS, fintech, healthcare, or e-commerce.

What Does a Typical Day Look Like?

A Rails Developer’s day revolves around building features, maintaining systems, and ensuring performance. You will:

• Review sprint tasks, picking up new feature tickets from the backlog.
• Write code for Rails applications, implementing business logic and integrating APIs.
• Run and review tests, ensuring new code meets quality standards.
• Collaborate with front-end and product teams, aligning features with user requirements.
• Optimize performance by tuning queries, adding caching, or fixing bottlenecks.
• Monitor error dashboards (Honeybadger, Rollbar) and deploy fixes as needed.
• Document changes and update repos to keep the codebase maintainable.

In essence: you ensure applications are reliable, scalable, secure, and continuously improving.

Key Metrics for Success (KPIs):

• Features delivered on time and aligned with requirements.
