Descripción del trabajo

We are looking for a Senior Data Scientist to lead the design, development, and deployment of data science solutions geared toward large-scale information analysis. The role requires proven experience bringing machine learning and deep learning models to production with massive data, applying A / B testing, supervised learning, anomaly detection, and pattern recognition practices.

The ideal candidate should be hands-on, with a solid background in statistics, algorithms, and programming, and capable of translating business problems (especially in the accounting, financial, and tax domains) into scalable, secure, and high-impact solutions.

Responsibilities

  • Design, train, validate, and deploy machine learning and deep learning models in production environments with big data
  • Implement advanced anomaly detection and pattern recognition techniques to identify irregularities, fraud, operational risks, or atypical behavior in the data
  • Execute A / B testing and statistical experimentation to validate hypotheses, measure impact, and optimize information analysis products
  • Collaborate with cross-functional teams (product, engineering, business, tax / accounting) to translate needs into data science use cases
  • Ensure data quality through pipeline cleaning, validation, orchestration, and monitoring processes
  • Develop and maintain technical documentation, metrics dashboards, and model performance reports
  • Propose new solutions based on predictive models, advanced analytics, and generative AI techniques that add strategic value

Profile Requirements

Academic

  • Bachelor's degree in Systems Engineering, Mathematics, Statistics, Computer Science, or related field (Master's / Doctorate desirable)
  • Experience

  • 6-12 years of experience in data science, with at least 3 years leading projects in production
  • Solid experience in supervised learning, A / B testing, anomaly detection, and pattern recognition
  • Experience putting ML / DL models with millions of records or transactions into production
  • Technical

  • Languages : Python (required), R, and SQL (advanced)
  • Experience with ML pipelines, MLOps, and cloud deployment (AWS, GCP, or Azure)
  • Knowledge of ML / DL frameworks (scikit-learn, TensorFlow, PyTorch)
  • Experience with anomaly detection (Isolation Forest, LOF, autoencoders, Prophet, ARIMA, robust statistics)
  • Experience in pattern recognition and predictive modeling (clustering, time series, sequences, recurrent neural networks)
  • SQL and NoSQL databases; experience with vector databases (Pinecone, pgvector, Milvus)
  • Strong data visualization skills (Matplotlib, Seaborn, Plotly, Power BI, Tableau)
  • Experience with model testing and cross-validation
  • Plus / Desirable (Nice to Have)

  • Knowledge of tax, accounting, ERPs, or the financial sector (banks, fintechs, insurance companies)
  • Experience in NLP and LLMs for information extraction and document classification
  • Experience in transaction fraud detection, credit risk monitoring, or tax irregularities
  • Familiarity with big data environments (Spark, Databricks, Hadoop)
  • Knowledge of programming languages such as Java, Scala, C++
  • Publications, presentations, or participation in data science communities
  • #J-18808-Ljbffr
