We are looking for a fullstack AI engineer to join an innovative RAG technology project from the ground up, focused on building a natural language communication system for client interactions. In this role, you will work directly with the CTO, contributing to both technical architecture and product evolution in a highly collaborative environment. You will be responsible for designing, developing, and scaling modern fullstack applications, with a strong emphasis on AI-driven solutions and LLM integrations.

Fullstack Developer Senior

We are looking for a Senior Full Stack Engineer to join the Finance engineering team. This is more than a hands-on development role. We're looking for someone who will elevate the team's engineering practices, mentor fellow engineers, drive technical excellence, and lead by example in building reliable, scalable, and maintainable software. You'll work on a mission-critical enterprise platform responsible for managing the complete lifecycle of product pricing across 100+ global markets. The platform powers everything from product catalog ingestion and cost modeling to pricing calculations and the distribution of finalized pricing data to downstream commerce and finance systems. Success in this role goes well beyond delivering features. *Job available only for Latin American residents*
