Senior Full-Stack Engineer / Product & Platform Owner - Remote Latam

Location: Remote, Latin America Type: Full-time

ABOUT THE ROLE

We’re looking for a strong Senior Full-Stack Engineer who is ready to take ownership of our internal and external platforms and evolve into a broader Product and Platform Owner role.

This position is ideal for someone who thrives in ambiguity, takes initiative, and can drive projects from concept to production without relying on perfectly defined requirements. You’ll be responsible for turning business ideas and AI-assisted prototypes into reliable, scalable, secure, and maintainable platforms.
