Job Description
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.
