Flex is a growth-stage, NYC headquartered FinTech company that is creating the best rent payment experience. It’s hard to believe that it’s 2024 and paying rent on time is expensive, inflexible, and difficult. We’re here to change that! Flex enables our users to pay rent throughout the month on a schedule that better fits their finances and budget. Our mission is to empower as many renters as possible with flexibility over their most significant recurring expense. After deliberately keeping a stealth profile as we built up unprecedented investor support and an enthusiastic user base, we are looking for motivated individuals to help us keep our mission growing.

• Stay up to date with the latest advancements in machine learning, statistics, and optimization techniques, and apply these innovations to improve model effectiveness.
• Communicate complex technical findings to non-technical stakeholders, creating clear visualizations and reports that convey insights in a digestible and impactful way.

• Master’s or Ph.D. in Statistics, Mathematics, Computer Science, or a related quantitative field.
• 6+ years of experience in data science with a focus on applying statistical modeling and machine learning to real world business problems.
• Expertise in time series analysis and forecasting models (e.g., ARIMA, Prophet, LSTM), as well as optimization techniques (e.g., linear programming, mixed-integer programming, constraint optimization) to solve complex business problems.
• Strong proficiency in Python, R, or similar programming languages, with fluency in statistical and machine learning libraries (e.g., scikit-learn, TensorFlow, PyTorch).
• Experience working with large datasets and leveraging cloud platforms (e.g., AWS, GCP) or distributed computing frameworks for data processing.
• Proven ability to apply complex statistical, machine learning, and data visualization techniques to drive measurable business outcomes.
