Data Science Engineer

Position Overview

As a Staff Data Science Engineer at REsurety, you’ll be a technical leader responsible for the architecture, maintenance, and rigorous validation of the models and tools that power REsurety’s core business. At the Staff level, you are an expert practitioner and a strategic thinker. You will lead the development of sophisticated software that characterizes risk and accelerates the global development of clean energy, serving as a bridge between research, power markets, and production-grade engineering.

This is a senior individual contributor role focused on technical leadership, system design, and cross-functional influence, not people management.

• Technical & Architectural Leadership
  • Own the end-to-end design and implementation of large-scale data and modeling applications, from ingestion and storage through modeling, validation, and production deployment.
  • Design systems that are modular, testable, and performant at scale, setting standards for code quality, security, and reliability across the organization.
  • Lead schema and data-model design in Snowflake and Postgres to support massive, evolving meteorological and power market datasets.
  • Establish and advocate for best practices in automated testing (unit, integration, data validation) for analytical and modeling workflows.
  • Advanced Time-Series Modeling & Research
• Drive the development and evolution of time-series forecasting models in Python for energy prices, emissions, and load.
• • Lead the evaluation, validation, and integration of new and complex data sources into production modeling systems.
  • Partner with research, power markets, product, and engineering to translate exploratory analyses into robust, production-ready systems.
  • Conduct deep-dive analyses into complex datasets (e.g., transmission constraints, solar irradiance, weather-driven dynamics) to surface market insights and modeling improvements.
• Technical Mentorship & Influence
  • Provide technical mentorship and design guidance to senior and mid-level engineers, raising the overall quality bar without direct people management.
  • Act as a Subject Matter Expert (SME) for clean energy project characterization and power market dynamics.
  • Act as a go-to technical authority for modeling architecture, data quality, and system-level tradeoffs.
  • Clearly communicate complex technical concepts, assumptions, and validation results to internal stakeholders and external customers.

• Bachelor’s or Master’s degree in Computer Science, Data Science, Engineering, or a related technical field.
• 10+ years of professional experience designing and operating data-intensive software systems in production environments.
• Expert-level proficiency in Python (including Pandas/Num Py) and SQL.
• Significant experience with time-series modeling, forecasting, machine learning, and statistical techniques in applied settings (e.g., Stats models, Scikit-learn, Tensor Flow, or PyTorch).
• Hands-on experience with cloud infrastructure (AWS, GCP, or Azure), including containerized workloads (Docker/ECS) and Infrastructure-as-Code (e.g., Terraform).
• Proven ability to lead technical initiatives across teams, making architectural decisions that balance correctness, performance, and maintainability.

• Domain expertise in clean energy, power markets, or energy analytics; experience in finance, offtake structures, or hedging is a strong plus.
• Experience building or supporting power flow or least-cost optimization models.
• Prior experience operating at a Staff or Principal level, leading cross-functional technical strategy and initiatives.
