Explore, test, and integrate AI tools (OpenAI, Claude, Hugging Face, embeddings, agents, etc.) into real product features.. . Deliver fast MVPs and prototypes to validate ideas and bring value quickly.. . Stay curious: experiment, iterate, and translate early concepts into production-ready code.. . What we’re looking for. . 5+ years as a fullstack or backend-heavy developer.. . Strong production experience with Node.js (Express/Nest) and ideally React.js.. . Ability to work with PHP legacy code during migration.. . Hands-on with Docker, REST APIs, testing frameworks, and CI/CD pipelines.. . 2+ years applying AI tools in real projects (not just experiments or theory).. . Experience delivering MVPs quickly and iterating based on feedback.. . A maker mindset: you balance curiosity and exploration with execution and delivery.. . . Mindset we value. . You’re a developer first: clean code, working features, and impact over perfection.. . You treat AI as a tool, not hype — and know how to make it useful.. . You’re proactive, self-driven, and thrive in uncertain or evolving environments.. . You enjoy being a senior voice in tech conversations while remaining hands-on.. . Company Location: Argentina.
