Ml / Ai Engineer — Train Llms. In Spanish. For Real.

We're building something that doesn't exist yet in Latin America: a domain-specific large language model
trained on a large Spanish-language corpus, deployed
on proprietary on-premise hardware, solving a real
problem for clients who are already waiting.
We can't tell you exactly what it is yet.
What we can tell you:
→ The corpus is real and large
→ The clients are real and paying
→ The hardware is ready
→ The team is small and the decisions matter
→ The person who joins now shapes the architecture
This is a fully on-site role in Mérida, Yucatán.
We want someone in the room — not because we don't
trust remote work, but because the knowledge needs
to live in the team, not in one person's laptop.
