About the Role
Engenheiro de Inteligência Artificial (IA) - 100% Remoto
We are looking for highly senior profiles to take ownership and lead our AI frontier, combining different data architectures, language models, and tool integration to create intelligent agents. Here, you will have the freedom and autonomy to explore cutting-edge technologies, but also the responsibility of being the engine that brings solutions to life and generates real value.
The position is 100% remote!
We are investing more and more in Artificial Intelligence. And to further accelerate our growth, we are looking for people who want to be happy in a Tech career.
What we expect from a Senior/Specialist profile here:
- Protagonism: You don't wait for the "card" to arrive refined. You investigate the business problem, perform POCs, propose the agent's architecture, choose the model, execute, test, and validate, ensuring alignment with stakeholders.
- Resilience and Autonomy: Complex integrations or lack of access are not impediments, they are steps. We expect you to work with Cloud, Security, and Data Engineering teams to unlock barriers and enable your experiments in production.
- End-to-End Vision: You understand from the capture of raw data (via Scraping, APIs, or Snowflake) to the impact of token costs and the final user experience (example: WhatsApp or internal systems).
- Technical Leadership: As a reference, you raise the bar for the team, bringing good engineering practices, suggesting new tools, and mentoring more junior profiles.
Responsibilities
As an AI engineer, you will focus on:
- Develop intelligent autonomous agents using modern frameworks like LangChain and Agno, creating flows that combine multiple tools.
- Create conversational agents with short and long-term memory, ensuring traceability and personalization for the customer.
- Experiment and integrate different LLMs (OpenAI, Gemini, DeepSeek, etc.), technically evaluating the use cases and performance/cost trade-offs.
- Structure and optimize vector databases (ChromaDB, FAISS) and implement advanced RAG techniques, connecting agents to corporate data in Snowflake or internal systems.
- Intelligent extraction mechanisms: Use web scraping (Crawl4AI) and parsing of complex documents (Docling) to feed knowledge pipelines.
- Automation of Actions: Integrate agents with APIs so that they not only respond but also perform tasks and update systems autonomously.
- Engineering Culture: Set up experimentation, versioning, and publication pipelines (MLOps) always focusing on scalability and clean code.
- Work with business areas to understand needs and transform them into practical solutions using AI agents.
Requirements
- Completed higher education in Engineering, Statistics, Mathematics, and Technology Area.
- Mastery of Python and familiarity with libraries focused on AI and data such as Transformers, Agno/LangChain/LlamaIndex, and scikit-learn.
- Experience with frameworks focused on autonomous agents and tool architectures.
- Experience with NLP and experience in integrating market LLMs (OpenAI, Gemini, DeepSeek, Cohere) in productive applications.
- Experience with API integrations (requests and FastAPI), data manipulation, and connection to databases (Snowflake preferred).
- Experience with vector databases for semantic search and RAG.
- Good software engineering practices, collaborative versioning with GitHub, and scalable solution architecture.
- Knowledge in deployment of LLMs in production and prompt engineering techniques.
Nice to Haves
- Experience in Machine Learning (supervised, unsupervised, and reinforcement learning)
- Experience in MLOps for automation of the model lifecycle.
- Knowledge about LLM optimization (quantization, fine-tuning, etc.).
- Experience with conversational AI projects integrated with WhatsApp.
- Previous experience as a technical reference in multidisciplinary teams.
