Mexico City Synergy Business Consulting, Inc. Jornada completa

Our client is hiring Senior AI Engineers in Mexico City on a contract basis. You will build production agentic AI systems that use LLMs and Vision-Language Models to automate visual and media workflows. The role is backend-focused, with room to own the product end to end. Senior and principal-level candidates are welcome. Fluent English is required.

What you’ll do

  • Build agentic harnesses and pipelines: tool use, multi-step reasoning, RAG, streaming, state management and multimodal integration.
  • Integrate and evaluate LLMs, VLMs, open-source models and third-party AI APIs.
  • Build scalable Python/FastAPI services and production APIs (REST, streaming, async).
  • Design event-driven and batch workflows for high-volume job orchestration (queues, EventBridge, DynamoDB Streams).
  • Run AI evaluation: eval datasets, regression evals, LLM-as-judge, human-in-the-loop review and production monitoring.
  • Work with cloud infrastructure, Terraform and CI/CD (Docker, GitHub Actions).
  • Contribute to search and retrieval systems (lexical and embedding-based).
  • Contribute to React/TypeScript frontends when needed.

What you bring

  • Production experience building agentic AI systems with LLMs/VLMs, beyond prototypes.
  • Experience evaluating AI systems for quality and reliability.
  • Strong backend fundamentals: APIs, async workflows, observability and production support.
  • Hands-on cloud experience (AWS, Azure and/or GCP).
  • Experience with the C4 model and other design artifacts.
  • Fluent English, written and spoken.

Nice to have

  • Technical lead or principal engineer experience, including mentoring.
  • Search and information retrieval at scale (Elasticsearch, OpenSearch, vector search).
  • Digital or broadcast media workflows; video or multimodal AI.
  • Terraform and serverless architecture.
  • Agent frameworks: LangGraph, OpenAI Agents SDK, Google ADK.
  • Image/video tools (FFmpeg, OpenCV); fine-tuning experience (LoRA, PEFT).
