We are currently seeking a highly skilled and intellectually curious Senior Data Scientist to join our remote analytics team. This role goes far beyond traditional data entry or routine reporting — it is a strategic position focused on building advanced predictive models, designing machine learning architectures, and driving analytical excellence across the enterprise. If you are passionate about deploying sophisticated algorithms in production environments, translating business challenges into mathematical solutions, and influencing executive-level strategy, this is the opportunity you have been waiting for at arenaflex.

Key Responsibilities

As a Senior Data Scientist at arenaflex, you will own the end-to-end lifecycle of advanced analytics projects — from ideation and exploration through model deployment and ongoing optimization. Your work will shape the future of healthcare intelligence, retail analytics, and customer experience strategy. Core responsibilities include:

• Model Development & Innovation: Build, validate, and deploy predictive models, recommendation engines, and optimization algorithms using state-of-the-art techniques in machine learning, statistical modeling, probability theory, and decision science. Continuously explore emerging methodologies and adapt them to arenaflex's evolving data ecosystem.
• Advanced Statistical Analysis: Apply rigorous analytical methods to massive, high-dimensional datasets. Leverage techniques such as regression analysis, time-series forecasting, customer segmentation, profiling, survey design, Bayesian inference, survival analysis, and anomaly detection to extract actionable insights.
• Algorithmic Engineering: Design and implement algorithms including decision trees, gradient boosting methods (XGBoost, LightGBM), K-means clustering, hierarchical clustering, support vector machines, association rule mining, and dimensionality reduction techniques such as PCA. Incorporate interpretable ML frameworks and fairness-aware modeling practices.
• Programming & Technical Stack: Write production-grade code primarily in Python, with additional proficiency in PySpark, SQL, and visualization libraries such as Matplotlib, Seaborn, and Plotly. Work with deep learning frameworks including TensorFlow and PyTorch to develop neural network architectures where appropriate.
• Cloud & Data Infrastructure: Utilize cloud-native services on Azure, including Azure Machine Learning, Databricks, and Azure Data Factory. Query and manage large-scale data warehouses using Snowflake. Build and maintain robust data pipelines that support both batch and real-time analytics workloads.
• Software Engineering Best Practices: Employ version control with GitHub, implement continuous integration and continuous deployment (CI/CD) pipelines, and operate within agile sprint cycles. Contribute to peer code reviews, documentation, and knowledge-sharing initiatives.
• Cross-Functional Collaboration: Partner closely with finance teams, clinical researchers, software engineers, product managers, and senior business leaders to define analytical requirements, identify high-impact use cases, and deliver insights that shape strategic direction.
• Executive Communication: Translate highly technical findings into clear, compelling narratives for non-technical audiences, including C-suite executives. Create dashboards, presentations, and written reports that inform decision-making and drive measurable business outcomes.
• Experimentation & Causal Inference: Design, execute, and analyze A/B tests and other controlled experiments to evaluate the effectiveness of interventions, product features, and operational changes.
• Mentorship & Leadership: Provide direct and indirect leadership to junior data scientists and analysts. Foster a culture of curiosity, rigor, and continuous learning within the analytics organization at arenaflex.
