Senior Ruby on Rails Developer; Product-Minded — Independent Contractor, Project

Senior Ruby on Rails Developer (Product‑Minded) — Independent Contractor, Project‑Based

We’re looking for an experienced Ruby on Rails developer who enjoys taking ownership of projects and delivering real outcomes — not just checking off tickets or juggling dozens of frameworks. This project‑based independent contractor role involves working closely with decision makers, shaping solutions, and taking responsibility for designing and implementing features end‑to‑end. We value engineers who think about the business context as much as the code, simplifying, reducing risk, and building software that lasts.

You’ll work across our stack – Rails 8, MySQL, Heroku, AWS, and limited React as we transition toward Hotwire – and contribute to decisions that directly impact product direction. We prefer candidates who can comfortably collaborate within CET or US time zones.

• Design and build secure, maintainable features in Ruby on Rails.
• Work from problem definition through design, implementation, and delivery.
• Keep solutions simple, safe, and easy to evolve.
• Translate business needs into clear technical approaches and trade‑offs.
• Contribute thoughtfully to architecture discussions.
• Write concise technical specs when needed.
• Collaborate asynchronously via Slack and Git Hub while communicating clearly and proactively.

• Ruby on Rails 8
• MySQL
• Heroku (deployments & ops)
• AWS
• React → Hotwire (new development direction)
• RSpec, Sidekiq

• Strong experience building real, production Rails applications.
• Someone who owns problems, not just assigned tasks.
• Ability to make pragmatic engineering decisions with trade‑offs in mind.
• Strong communication – explaining why matters as much as what.
• Interest in understanding the business and customer impact.
• Comfortable working independently, yet collaborative when decisions matter.

• Experience with Hotwire.
• Heroku or AWS familiarity.
• Experience simplifying or refactoring complex systems.
• Prior independent contractor or project‑based work experience.

• Project‑based, meaningful ownership – you see the impact of your work.
• 100 % remote, with preference for CET / US overlap.
• Full‑time contractor scope.
• A practical engineering culture: clarity, simplicity, and maintainability.
• Direct collaboration with decision makers, not layers of management.
• Realistic expectations – we care about quality, not heroics.

Send a short note to with: a brief description of your experience with Rails, a link to projects or Git Hub (optional if none), and one example of a problem you simplified instead of over‑engineering. Feel free to mention availability, timezone, and rate expectations.
