Celara

Senior Ruby on Rails Engineer (Remote | LATAM)

We’re looking for a Senior Ruby on Rails Engineer to join a US-based product team building and maintaining business-critical internal applications. This is a long-term engagement for someone who’s comfortable operating with ownership, ambiguity, and high delivery standards.

What you’ll do

  • Build and maintain production Ruby on Rails applications

  • Own features end-to-end, from requirements to deployment

  • Collaborate closely with distributed engineering and product teams

  • Participate in sprint planning, refinement, and continuous delivery

  • Actively communicate progress, risks, and tradeoffs in a remote setup

What we’re looking for

  • 5+ years of professional experience as a backend or full-stack engineer

  • Strong, hands-on Ruby on Rails experience in production environments (non-negotiable)

  • Experience working on internal tools or high-impact business systems

  • Ability to work autonomously and take full ownership of assigned work

  • Comfortable in fast-moving, agile teams with minimal hand-holding

  • Strong English communication skills

Nice to have

  • Frontend exposure with React and TypeScript

  • Experience in data-heavy or operational systems

  • Prior work with US-based teams and time-zone overlap

Work setup

  • Fully remote

  • Full time overlap with US East Coast hours

  • Long-term contract engagement

Important notes for recruiters

  • This is a senior-only role. No junior or early mid-level profiles.

  • Ruby on Rails experience must be real and recent. Not “can learn Rails quickly”.

  • We’re prioritizing ownership, communication, and reliability as much as technical depth.
