**Who are we looking for?** -------------------------- We are looking for a senior Data Science and Machine Learning professional with experience in leading end-to-end solutions, from identifying business opportunities to implementing and operating models in production. Someone with a strong analytical vision, autonomy, proficiency in Python and SQL, and the ability to transform data into high-impact business decisions. Leading the **analytical intelligence** front, end-to-end: elevating business decisions currently made by heuristic rules to **predictive models** and, on the roadmap, to **formal optimization**. **What will the day-to-day be like?** -------------------------- **Activities:** * Map with business areas the decisions that require analytical support, gather available data, and **prioritize predictive scenarios** for hypothesis testing; * **Measure the baseline** and define business metrics before committing to gains; * Develop and validate models (prediction, ranking of alternatives, recommendation), with **explainability** of the suggestions; * Build and operate the **inference service** in Python/FastAPI, on internally approved AI platforms; version the model and dataset; monitor performance and drift; * Roadmap: formulate decisions as a **constrained optimization problem**, solved by a solver. **Required skills and experience:** -------------------------------------------- * **Senior experience in end-to-end ML/Data Science** — from problem formulation to the model in production, not just notebook exploration; * **Scientific Python**: pandas, numpy, scikit\-learn and at least one of XGBoost/LightGBM/CatBoost; * **Inference service**: API in Python (FastAPI or equivalent), versioning, reproducibility, and monitoring; * **Strong SQL** and autonomy to investigate large and poorly documented relational databases; * **Correct validation**: temporal separation, data leakage, overfitting, metric aligned with the business; * Explain the results to non-technical stakeholders. **Technical English**. **What will be a differentiator for us?** --------------------------------------- * **Mathematical optimization / operations research**: ILP, CSP, solvers (OR\-Tools, Gurobi, CPLEX), multi-objective, heuristics — this is the direction of the roadmap; * **Applied generative AI** (RAG, response evaluation), with awareness of cost and hallucination. **What are the benefits of being a Ventureiro or Ventureira:** --------------------------------------------------------------- * Food/meal voucher with values above the market average; * Medical and dental plan; * Monthly home office allowance (remote or hybrid work); * Monthly mobility allowance (hybrid or on-site work); * Parental leave (maternity \- 6 months; paternity \- 20 days); * Daycare assistance up to 36 months of age; * Care4All program (support network for emotional and physical health); * Wellhub; * Access to Conexa Saúde (online mental health platform); * Access to the SESC network; * Holiday bridging and year-end recess; * Life insurance; * Private pension; * Scholarship, certification assistance, and Udemy license; * Corporate English (access to Voxy or Michigan); * Access to our Corporate University (vnt/school); * PPR; * Guapeco (pet health plan). The position is also open to people with disabilities! **Did you like it? Then apply and participate in our selection process!**
