Role Overview

We are seeking a highly skilled Senior Machine Learning Data Scientist to join our Trust & Safety and Last‑Mile Optimization teams. In this remote role, you will design, develop, and deploy sophisticated predictive models that detect driver abuse, forecast delivery demand, and power real‑time decision engines. Your work will directly influence the safety of our driver community, the efficiency of our logistics network, and the overall satisfaction of our customers.

Key Responsibilities

• Design and implement machine‑learning models (e.g., CNNs, RNNs, decision trees, random forests, clustering, K‑means, t‑SNE) to identify driver abuse patterns and flag high‑risk behaviors for the Trust & Safety team.
• Develop and maintain end‑to‑end pipelines that automate daily and hourly driver‑abuse scoring, ensuring robust data ingestion, feature engineering, model training, and deployment.
• Build ensemble and time‑series forecasting models to predict order volume in real‑time, enabling dynamic resource allocation and on‑time delivery guarantees.
• Collaborate with product managers and engineering partners to translate business requirements into scalable analytical solutions, incorporating feedback from commercial stakeholders and account executives.
• Perform rigorous model evaluation using statistical tests (Chi‑square, ROC‑AUC, RMSE) and validation techniques to guarantee accuracy, robustness, and fairness across diverse driver populations.
• Create interactive dashboards and visualizations (Python – Matplotlib, Plotly, Seaborn; R – ggplot2; Tableau) that communicate model insights, performance metrics, and actionable recommendations to leadership.
• Lead data‑exploration initiatives, extracting and cleaning large datasets using Python, Pandas, and SQL, and applying statistical analysis to uncover hidden distributions, trends, and outliers.
• Maintain version control and collaborative development workflows using Git and GitHub, ensuring reproducibility and seamless hand‑offs between data science and engineering teams.
• Mentor junior data scientists and analysts, fostering a culture of best practices, continuous improvement, and knowledge sharing.
• Stay abreast of emerging AI/ML research, tools, and industry trends, proactively recommending innovative approaches to enhance arenaflex’s analytical capabilities.

Essential Qualifications

• Education: Bachelor’s degree (or equivalent) in Statistics, Mathematics, Computer Science, Economics, Data Science, or a related quantitative field.
• Experience: Minimum 2 years of professional experience in data science, machine learning, or advanced analytics, preferably within a logistics, e‑commerce, or transportation context.
• Technical Skills: Proficiency in Python (including libraries such as scikit‑learn, TensorFlow/PyTorch, Pandas, NumPy), SQL, and data visualization tools (Matplotlib, Plotly, Tableau, ggplot2).
• Modeling Expertise: Demonstrated ability to build, tune, and evaluate both parametric and non‑parametric models, including deep learning architectures, ensemble methods, and clustering algorithms.
• Statistical Acumen: Strong foundation in statistical inference, hypothesis testing, distribution analysis (normal, skewed, CLT), and error metrics.
• Communication: Excellent written and verbal communication skills, with the ability to translate complex technical concepts into clear business insights for diverse audiences.

Preferred Qualifications

• Master’s or Ph.D. in a quantitative discipline.
• Hands‑on experience with time‑series forecasting (ARIMA, Prophet, LSTM) and demand‑prediction pipelines.
• Familiarity with cloud platforms (AWS, GCP, Azure) and containerization (Docker, Kubernetes) for model deployment.
• Prior work on fraud detection, driver safety, or risk‑scoring systems.
• Experience with A/B testing, causal inference, and uplift modeling.
• Knowledge of data engineering concepts, including ETL processes, data lake architecture, and big‑data technologies (Spark, Hadoop).

Core Skills & Competencies

• Analytical Thinking: Ability to dissect complex problems, identify root causes, and propose data‑driven solutions.
• Collaboration: Proven track record of working cross‑functionally with product, engineering, operations, and business stakeholders.
• Innovation: Curiosity to explore new algorithms, tools, and methodologies that can give arenaflex a competitive edge.
• Adaptability: Comfort operating in a fast‑paced, remote environment with shifting priorities and evolving business needs.
