We are seeking an AI Engineer with 5+ years of hands-on experience in software development, who thrives on solving complex problems and building products end-to-end. This role is ideal for an engineer who goes beyond traditional development boundaries — someone who can take ownership of ambiguous ideas, rapidly turn them into working solutions, and continuously iterate using modern tools, including AI.

The position is available in Brazil and offers a fully remote job.
