Full 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.
