Why This Role Matters

As a Senior Data Scientist at arenaflex, you will be at the heart of our transformation journey. You will harness sophisticated data‑science techniques, predictive analytics, and machine‑learning (ML) models to solve real‑world business challenges, influence strategic decisions, and drive measurable impact across the organization. This is a fully remote position that offers the flexibility to work from anywhere while collaborating with cross‑functional teams spanning finance, product, engineering, and senior leadership.

Key Responsibilities

• Design, develop, and deploy advanced ML models using statistical modeling, probability theory, and other quantitative methods to address complex business problems.
• Extract, clean, and explore massive data sets, turning raw information into clear, business‑focused analytical solutions.
• Apply predictive statistical techniques, customer segmentation, survey design, and data mining to uncover hidden patterns and opportunities.
• Build and maintain production‑grade data pipelines and ML workflows with Python, PySpark, TensorFlow, PyTorch, and related libraries.
• Implement supervised and unsupervised learning algorithms—including decision trees, regression, XGBoost, K‑means clustering, anomaly detection, and interpretable Bayesian models—to generate prescriptive recommendations.
• Leverage cloud platforms (Azure, Databricks) and data‑warehouse technologies (Snowflake) to scale analytics solutions and ensure high‑performance computing.
• Collaborate with software engineers to integrate ML models into CI/CD pipelines, using GitHub, agile methodologies, and automated testing frameworks.
• Partner with finance, product, and business stakeholders to define product requirements, translate technical concepts into business language, and deliver data‑driven insights.
• Communicate findings through compelling visualizations, executive‑level presentations, and written reports that influence strategic direction.
• Mentor junior data scientists and analysts, fostering a culture of continuous learning and technical excellence.

Essential Qualifications

• Bachelor’s degree in Computer Science, Statistics, Mathematics, Data Science, or a related STEM field, with at least four years of professional experience in data science, machine learning, or quantitative analysis. OR a high‑school diploma/GED with a minimum of seven years of relevant experience.
• Advanced degree (M.S. or Ph.D.) in a quantitative discipline is highly desirable.
• Proven experience working with large‑scale, complex data sets to develop, optimize, and operationalize ML and predictive models.
• Expertise in SQL, Python, and PySpark (or comparable big‑data languages).
• Strong background in exploratory data analysis, feature engineering, pattern detection, statistical visualization, and insight extraction.
• Hands‑on experience building classification models, decision trees, and ensemble methods such as XGBoost.
• Demonstrated ability to apply both supervised (linear/logistic regression, time‑series, SVMs) and unsupervised (K‑means, hierarchical clustering, PCA) learning techniques.
• Experience with cloud‑based ML platforms, distributed computing, data pipelines, and serving layers.
• Track record of designing and analyzing A/B experiments to drive product and business decisions.
• Exceptional communication skills—able to translate rigorous technical concepts for non‑technical audiences and influence cross‑functional teams.
• Ability to thrive in ambiguous, fast‑paced environments, prioritize competing demands, and deliver high‑quality results on schedule.
• Minimum two years of experience contributing to financial decision‑making processes within an organization.
• Leadership experience—direct or indirect management of teams, project ownership, and mentorship responsibilities.
• Willingness to travel up to 10 % of the time for on‑site business engagements, both domestically and internationally.

Preferred Qualifications

• Ph.D. in a quantitative field such as Computer Science, Statistics, Physics, Mathematics, or Data Science.
