Job description

ImagineX is a tech company that deploys AI-assisted teams to build and secure mission-critical enterprise solutions with our clients – spanning software, data, and AI. Structured like a software company, not a traditional consultancy, we blend deep technical expertise with authentic values, achieving world-class satisfaction (NPS 91). Our dedicated teams specialize in software, data, and AI across the U.S. and LATAM, bridging the gap between boutique agility and enterprise scale.

We are searching for a Ruby on Rails Developer for a dedicated client project, building and maintaining full-stack features across the client's Rails back end and Vue.js front end. You will own work from database design through the user interface, shipping reliable, well-tested code alongside our team and the client's stakeholders. We are looking for a well-rounded technologist: Rails and Vue are the core of this engagement, and experience across other languages is a real plus.

This is a 100% remote role, and we're open to full-time or 1099 contractor.

• Design database schemas and write efficient queries in PostgreSQL, diagnosing slow queries and N+1 issues
• Review teammates' pull requests and give clear, constructive feedback

Nice to have

• Versatility across multiple programming languages, such as Go, Java, Python, TypeScript or Node.js, and comfort picking up new ones as the client's needs change
