What’s the difference between an AI engineer and an ML engineer?
An ML engineer trains and deploys models; an AI engineer builds products on top of existing models (LLMs, APIs), RAG, agents, features. Most startups need the latter to ship.
AI engineer vs AI evaluator, what’s the difference?
Engineers build the AI product; evaluators judge model output quality. If you need humans to rate and red-team output, see hire AI evaluators in Latin America.
Can your AI engineers work full-stack?
Yes, that’s the point. They build the model integration, the backend and the frontend, so you don’t need three hires to ship one feature.
What AI / LLM stacks do they know?
Python with LangChain / LlamaIndex, vector DBs like pgvector and Pinecone, the major model APIs, plus TypeScript, Node.js, React and Next.js for the product layer.
Can they ship to production, or just prototype?
Ship. We specifically screen out demo-only candidates, our test includes evals, monitoring and cost considerations.
Can they build agents, not just chatbots?
Yes. Tool use, multi-step planning, memory and retrieval, guardrails, evals and tracing. We screen on a real agent or RAG build, so you see how they handle failure cases before you hire.
Do they work with our existing stack and vendors?
Yes. The major model APIs, LangChain / LlamaIndex or plain SDKs, pgvector or Pinecone, memory layers, and tracing tools. They join your repo and follow your standards from day one.
Should I hire an AI engineer or use your AI Development service?
Hire when you want a dedicated engineer on your team long-term; use our AI Development service when you want us to build it with you. We’ll help you decide on the call.
How senior are these engineers?
Mid-to-senior. People who’ve owned features end-to-end and can make architecture calls without hand-holding.
Can you hire a Solana or Web3 developer in Latin America?
Yes. Web3 and Solana talent is a specialty pool in Latin America — mostly concentrated in Argentina, Brazil, and Colombia, where crypto-native startups like Ripio, Buenbit and Bitso trained a generation of senior blockchain engineers. We place Solana, Ethereum, and full-stack Web3 developers as part of the AI/full-stack engineer track.
What does a senior AI engineer in LatAm cost?
Senior AI and ML engineers in Latin America run $80,000 to $110,000 per year base, roughly 50 percent below equivalent US senior rates of $180,000 to $240,000. Full stack generalists are closer to $66K to $102K. See the Compensation Report for country specifics.
