Senior Software Engineer

At Platzi, we’re building AI-powered products that are transforming how people learn. We’re looking for a Senior Software Engineer with strong software development foundations and proven experience integrating AI into real-world products.

This role is perfect for someone who has shipped production-grade software and already worked hands-on with AI frameworks, APIs, or data pipelines. You don’t need to be an AI researcher, but you should know how to apply AI tools effectively while maintaining high engineering standards.

• 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.

• 4+ years of experience as a Software Engineer (backend or fullstack preferred).
• Strong command of Python (FastAPI, Django) and/or TypeScript (Node.js, Cloudflare Workers).
• Solid background in software design principles, clean code, and system architecture.
• Hands-on experience integrating AI into products: LLM APIs, embeddings, retrieval-based architectures (RAG), or data pipelines.
• Familiarity with frameworks such as LangChain, LlamaIndex, or HuggingFace.
• Ability to work with unstructured data and transform it into usable product outputs.
• Comfort with cloud environments and DevOps practices.
• English level B2 or above — able to hold technical discussions.

• Experience deploying and optimizing AI-powered features end to end.
• Knowledge of model fine-tuning or open-source AI tools.
• Contributions to open-source projects or AI/engineering communities.
• Familiarity with distributed systems or real-time data processing.
