Professional-level English is required ## Description As a Senior Data Scientist in the Data Corporate team, you will turn fundamental company data into high-impact, research-ready features and signals that feed the alpha models designed and owned by our Researchers. Working side by side with them, as well as with data engineers and external providers, you will take full ownership on moving from raw and legacy to robust, point-in-time datasets and then explore those datasets, proposing and validating new features, signals, and statistical or machine-learning approaches. This is a data-science-first, senior individual-contributor role for a top-tier practitioner with deep fundamental-data expertise and sharp analytical judgement, directly accountable for data quality, research usability, and measurable alpha contribution, within an ambitious, intellectually demanding environment that remains supportive, innovative, and collaborative., Data Expertise & Vendor Ownership Act as the team's subject-matter expert on fundamental company data (financial statements, estimates, corporate actions, ownership, reference data), mastering vendor schemas, accounting conventions, restatements, and temporal characteristics Own technical and data-quality relationships with providers, from evaluation and onboarding to escalation, roadmap discussions, and service reviews Evaluate new data sources, methodologies, and technologies, separating durable research value from vendor claims and short-lived trends Feature & Signal Research Design economically grounded features from fundamental data and assess their stability, coverage, turnover, and behavior across markets and regimes before they enter alpha research Develop and critically evaluate statistical and machine-learning approaches, prioritizing economic intuition, interpretability, point-in-time integrity, and genuine out-of-sample robustness Proactively identify new use cases by connecting accounting, corporate, and market-structure knowledge to systematic investment questions, and test whether they deliver differentiated alpha Research Partnership & Team Leadership Work side by side with Researchers to understand their needs, while independently proposing datasets, features, signals, diagnostics, and reproducible workflows that open new research directions (alpha model ownership remains with Quantitative Researchers) Raise the bar for the team through design reviews, documentation, mentoring, and active knowledge sharing across research and engineering Data Quality & Platform Stewardship Take ownership of the Data Corporate Platform and its curated-data pipelines, rationalizing legacy implementations and improving documentation, lineage, discoverability, and fitness for quantitative research Define and enforce standards for point-in-time correctness, survivorship-bias control, revisions, outlier treatment, completeness, and cross-provider reconciliation Maintain and enhance production pipelines (testing, monitoring, incident resolution, backfills, schema changes), with data engineering support where relevant
