[Hiring] Senior Data Scientist @Metova

Role Description

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.

• 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.

Qualifications

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

Requirements

• 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.

Benefits

• 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.
