What are some common challenges faced by Ruby on Rails contractors when joining new projects, and how can they be addressed?

Ruby on Rails contractors often face the challenge of quickly ramping up on existing codebases, which may have varying coding standards or lack comprehensive documentation. To address this, it's helpful to allocate initial time for codebase exploration and to communicate proactively with the team about architectural decisions and project expectations. Collaborating closely with in-house developers and participating in regular stand-ups or code reviews can also smooth the transition and ensure alignment with project goals.

What are the key skills and qualifications needed to thrive as a Ruby on Rails Contractor, and why are they important?

To thrive as a Ruby on Rails Contractor, you need strong proficiency in Ruby, Rails framework, web development fundamentals, and experience with relational databases, typically demonstrated through a portfolio or relevant work history. Familiarity with version control systems like Git, cloud platforms (e.g., AWS or Heroku), and testing frameworks such as RSpec is often required. Excellent problem-solving skills, effective communication, and the ability to work independently are standout soft skills for this role. These skills and qualities are crucial to deliver high-quality, scalable solutions on time while collaborating remotely with clients or teams.

Job description

Come build the rails of B2B commerce in hospitality, starting with hotels
What excites you
  • You're someone who has worked on early-stage teams, perhaps even as a founder, and love wearing multiple hats (to a healthy extent).
  • You've seen products come to life from just a spark of an idea, and even if things don't quite pan out, you're motivated by the process of making something from nothing.
  • You want to work on software that has real, tangible value to deliver to the people who need it, even if the solution can be basic or 'unsexy' sometimes.
  • You're an expert at prioritization and time management who can gracefully adapt to new facts on the fly as you make tradeoffs between customer and business needs.
  • You're focused on quality, not quantity. You can distill complex systems in the service of building delightful yet powerful applications.

What excites us
  • You have 8+ years of hands-on experience as a senior contributor to teams that have proved they can ship great products.
  • You're a backend specialist with deep expertise in server-side technologies (Ruby on Rails / Node.js / Postgres) and API design.
  • You have solid object-oriented design and programming skills with experience architecting solutions for complex data-intensive systems.
  • You have hands-on experience with DevOps practices, infrastructure automation, and cloud deployment (AWS, Docker, CI/CD pipelines)
  • You understand system scalability, performance optimization, monitoring, and have experience with infrastructure as code (Terraform).
  • You have experience building software that enables money movement with a penchant for digitizing historically paper-based processes.
  • You have experience with data modeling, database optimization, and ensuring data integrity in financial systems.
  • You have experience building and maintaining search infrastructure, ideally with Elasticsearch or similar technologies.
  • You try to give back to the development community as a contributor to Open Source Software projects or other pro-bono avenues.

Working at Folio
  • Folio is a Ruby on Rails app with Typescript Node.js automations and Elasticsearch deployed to AWS.
  • Our engineering team meets daily for standup (except Friday) and otherwise keep meetings to a minimum.
  • We're a remote-first company. Quarterly, we travel to work together in-person and stay with one of our hotel partners.
  • For the most part, we rely on Google Meet, GitHub, Linear, Notion, and Slack to make decisions and get things done day-to-day.

What we value
  • Craft. We take pride in our work, find joy in execution, and believe that the best companies are built at a steady yet resilient pace.
  • Optimism. We believe in ourselves and each other and know anything is possible with the right amount of hustle and grit.
  • Ownership. We love making things better and have a strong sense of shared responsibility over everything we create together.
  • Hospitality. The industry we're building for has a culture of service to others, and we bring that energy to how we work together each day.
