Descripción de la vacante

Wizeline is seeking a Senior AI Agent Engineer to design production-grade, tool-augmented AI agents. You will build multi-step reasoning pipelines, integrate them with business systems, and ensure scale, safety, and maintainability.

You’ll own the full agent lifecycle from scoping to monitoring and tuning to meet client needs. You’ll work on agent orchestration, data integration, and continuous optimization, collaborating with a global team to deliver reliable AI-powered products that comply

Formación

• Excellent communication and collaboration skills.
• 5+ years of software engineering in production environments (TypeScript/Node, Go, or Python) with strong API design, testing, and debugging habits.
• Hands-on LLM experience (GPT, Claude, Gemini, or fine-tuned OSS models): prompt engineering, function/tool calling, model selection, and evaluation.
• Retrieval-Augmented Generation (RAG): embedding pipelines and semantic search with Pinecone, Weaviate, etc.
• Agent orchestration expertise: LangChain/LangGraph, OpenAI Agents SDK, CrewAI, or equivalent frameworks for tool-augmented reasoning loops.
• ML-/DevOps literacy: containerization, CI/CD, GPU/AI infra, caching, automated evals for nondeterministic systems.
• Experience enforcing security guardrails & PII protection in user-facing AI products

Are you a fit?

We're looking for a Senior AI Agent Engineer with a passion for building production-grade, tool-augmented AI agents that blend cutting-edge LLM techniques with solid software-engineering discipline. In this role, you'll design multi-step reasoning pipelines, wire them to business systems, and harden them for scale, safety, and maintainability — helping enterprise customers launch conversational agents that solve real problems, take real actions, and comply with real-world policies. You'll play a key role in agent design and delivery, tool and data integration, LLM orchestration and planning, and continuous optimization — owning the full agent development life-cycle from scoping through monitoring and iterative tuning. If you're passionate about AI R&D, agentic systems, and building reliable, guard-railed AI products, we'd love to meet you.
