Frequently Asked Questions:
What does a AI Agent Developer do?
An AI Agent Developer builds autonomous LLM-driven systems that take multi-step actions: research agents, sales prospecting agents, customer support agents, coding agents, and the orchestration layer underneath. They write prompts, design tool-use schemas, build evaluation harnesses, and ship agents that operate in production with real cost and reliability constraints. The role is the natural evolution of the AI Engineer for teams shipping autonomous workflows.
How much does it cost to hire a AI Agent Developer?
AI Agent Developers sit near the top of the AI hiring market. Expect an average U.S. salary of $14,000 per month compared with an average Latin American salary of $6,000 per month, creating potential savings of up to 57%. LatAm has built a strong agent-developer bench from ML and software engineering backgrounds, with engineers shipping production agents at U.S. AI-native companies.
Can a U.S.-based company hire a remote AI Agent Developer from Latin America?
Yes, agent development is fully remote-native. South contracts the developer locally, runs payroll and compliance, and bills you monthly. They join your GitHub, Notion, and observability stack day one. Time-zone alignment matters: agent debugging often needs synchronous review of trace logs and prompt iterations.
What skills should I look for when hiring a AI Agent Developer?
Strong Python or TypeScript, fluency with at least one agent framework (LangGraph, CrewAI, OpenAI Agents SDK, or homegrown), and the rigor to build evals before shipping. Look for engineers who have shipped multi-step agents to production and can walk through real failure modes (loops, hallucinated tool calls, cost runaway). Run an agent design interview on a real workflow.
What tools and frameworks should a AI Agent Developer know?
OpenAI, Anthropic, and open-source model APIs. LangGraph, CrewAI, OpenAI Agents SDK, or AutoGen for orchestration. LlamaIndex or LangChain for retrieval. Pinecone, Weaviate, or pgvector for vectors. Braintrust, LangSmith, or Promptfoo for evals. Python with FastAPI or TypeScript with Hono for the service layer. Datadog or Honeycomb for observability.
How is a AI Agent Developer different from a AI Engineer?
An AI Engineer ships AI features broadly: chat, retrieval, fine-tuning, basic tool-use. An AI Agent Developer specializes in autonomous, multi-step systems: planning, tool calling, memory, error recovery. Agent work is more demanding on system design and eval rigor. For a single-step LLM feature, an AI Engineer is enough. For a multi-step autonomous workflow, hire an Agent Developer.
How can South help me hire a AI Agent Developer?
South vets LatAm agent developers through technical interviews, take-home agent design exercises, and code reviews of prior projects. You see a shortlist in seven to ten days, run your own interviews, and onboard inside two to three weeks. South handles the contract, monthly payments, and a replacement guarantee.

Interview Questions:
- Design a research agent that browses the web, synthesizes a 10-source report, and stays under $0.50 per run.
- I tell you our agent loops indefinitely 3% of the time in production. Walk me through your investigation.
- How do you decide between a single-prompt approach versus a multi-step agent for a workflow?
- Walk me through how you'd build an eval harness for a sales-research agent where ground truth is subjective.
- How do you handle tool-call hallucination when the model invents a function that doesn't exist?
- Walk me through your approach to memory and context management for an agent running 30+ turns.
- When do you use a planner-executor pattern versus a single agent with tools?
- How do you cap cost on an agent that runs autonomously without per-call human review?
- Pitch me on an agent architecture decision you'd push for inside our company in your first 30 days.
- What's a common agent failure mode that gets ignored, and how would you catch it before production?
