About the role

Key responsibilities & impact
  • Own the full model lifecycle — feature engineering, training, validation, registration, and deployment
  • Monitor models in production and lead retraining when performance degradation or drift occurs
  • Maintain and evolve CI/CD pipelines that promote models and pipelines across development, staging, and production environments
  • Automate and productionize model and agent evaluation pipelines in support of Data Science
  • Build and maintain reusable internal metrics packages for standardized experiments
  • Operate the infrastructure for fine-tuning language models
  • Administer the AI Gateway, including model routing, rate limits, and cost control and attribution
  • Ensure feature, experiment, and model governance is aligned with Afya policies
  • Serve as the technical bridge between Data Science, AI Engineering, Data Engineering, and SRE
  • Apply scalability, security, and cost-efficiency practices to ML/AI infrastructure

What you’ll need
  • Databricks as the primary platform, serving as a technical authority: Model Serving, Unity Catalog, and Asset Bundles, with MLflow for model registration, versioning, and evaluation
  • Equivalent experience with SageMaker, Vertex AI, or Azure ML is also valued, along with a willingness to deepen expertise in Databricks
  • Advanced Python, SQL, and Apache Spark / PySpark, applied to production Machine Learning pipelines (scikit-learn, XGBoost)
  • CI/CD and infrastructure as code for promoting models and pipelines across development, staging, and production: GitHub Actions, Terraform (or equivalent IaC), cloud platforms (Azure, AWS, or GCP), and secrets management
  • Production model operations: version promotion and rollback, performance, cost, and drift monitoring, and response to endpoint incidents
  • Statistical interpretation of evaluation results to determine version promotion or rollback, with governance of experiments, model versions, and inference data
  • Exposure to at least one LLMOps area: AI Gateway, evaluation (evals) pipeline automation and reusable internal metrics packages, or LLM fine-tuning infrastructure
  • Senior technical leadership without people management, including architecture definition, negotiation of technical contracts, and mentoring mid-level engineers
  • Completed higher education or a technology degree in Computer Science, Systems Analysis and Development, Engineering, Information Systems, Statistics, Mathematics, or a related field
  • Advanced technical English for reading documentation, release notes, and papers
  • Established experience in Machine Learning Engineering / MLOps, with demonstrated experience supporting models in production: automated training, validation, promotion, deployment, monitoring, and retraining
