At Platzi, we’re building AI-powered products that are changing the way people learn. We’re looking for an AI Software Engineer with a strong technical background—someone who knows how to integrate language models, embeddings, and agents into real-world systems that are scalable and maintainable.

As a Software Engineer, you must know sound principles about software development, clean architectures, and how to write good code. You need to understand the basics of frontend, backend, and DevOps, and be strong with at least one of them.

This role is for someone who doesn’t just use LLMs, but understands how they work, how to optimize and deploy them, and most importantly, how to turn them into real products.

• Design and build end-to-end AI-powered features that directly impact how people learn at Platzi.
• Use LLMs, agents, embeddings, RAG, and fine-tuning not just as tools, but as core building blocks to deliver personalized, intelligent product experiences.
• Work with multiple LLM providers: OpenAI, Anthropic, Gemini/Vertex AI, Mistral AI.
• Integrate frameworks like LangChain, LlamaIndex, and similar tools into real data pipelines and products.
• Process unstructured data (PDFs, images, videos) and extract meaningful information.
• Build robust backend services with Python, FastAPI, and Django (bonus points if you also know TypeScript and have worked with Cloudflare Workers or Hono).
• Stay up to date with the latest AI advancements and bring those improvements to our stack.
• Read, understand, and apply insights from technical papers and research reports.
• Collaborate across teams to deliver reliable, maintainable software that scales.

• 3+ years of experience as a Software Engineer or in a similar role.
• Strong command of Python and experience with frameworks like FastAPI or Django.
• Familiarity with AI/ML fundamentals, especially LLMs, embeddings, and retrieval-based architectures (RAG).
• Experience working with APIs from OpenAI, Anthropic, Gemini/Vertex AI, or Mistral.
• Solid understanding of software design principles, clean code, and system architecture.
• Comfortable integrating AI frameworks like LangChain, LlamaIndex, or similar.
• Experience processing unstructured data: PDFs, images, videos, or audio.
• Familiarity with backend, frontend, and DevOps — strong in at least one of them.
• Able to read and apply insights from technical papers and research.
• English level B2 or above: you can comfortably engage in technical discussions.

• Experience shipping AI-powered features end to end.
• Knowledge of TypeScript and Cloudflare Workers or Hono.
• Familiarity with model fine-tuning or open-source AI tools.
• Contributions to open-source projects or AI communities.
