Job description

At Zarego, we are on the lookout for an AI-Assisted Software Engineer to join our team. If you are passionate about architecting modern web solutions and thrive when solving complex technical puzzles — and you've made AI a real part of how you build software — we want to meet you!

What we're looking for:

Experience: 5+ years of professional experience building, shipping, and maintaining production-grade web applications.
Backend Expertise: Deep, hands-on experience building robust, scalable backend applications using Ruby and Ruby on Rails.
Frontend Proficiency: Solid experience using React and modern JavaScript/TypeScript to build high-performance, responsive user interfaces.
Software Fundamentals: Strong software engineering fundamentals, including clean code, relational database design, API architecture, and a solid testing mindset (using RSpec, Minitest, or similar frameworks).
AI-Assisted Development: Regular user of modern AI-assisted development tools (such as Copilot, Cursor, Claude Code, or similar) across the full development lifecycle — implementation, debugging, testing, documentation, and code reviews — while maintaining high engineering quality.
Engineering Judgment with AI: Strong judgment about where AI genuinely accelerates the work and where it doesn't. You review what AI produces with the same rigor you'd apply to any teammate's code, and you own the result either way.
Collaboration & Ownership: Ability to take ownership of features from design to production, collaborating effectively with product managers, designers, and fellow engineers in fast-paced environments.
Bilingual Communication:
- Advanced English (C1–C2) to participate in technical reviews, architecture discussions, and collaborate with international stakeholders.
- Professional Spanish proficiency.
Location: Remote. Candidates must reside in Latin America (LATAM).

Nice to have:

Geospatial Data: Familiarity with PostGIS and working with geopositioning/location-based data.
Familiarity with modern cloud platforms (AWS, Heroku, etc.), deployment workflows, and CI/CD practices.
Bachelor's degree in Computer Science, Software Engineering, or a related technical field.
