About the Role

Own the unit economics of network costs by building models and optimizations that determine the most cost-efficient configuration for every line on our networks. Validate models against financial data and translate analysis into actionable business decisions, emphasizing business judgment alongside mathematical expertise.

Responsibilities

  • Build and run cost models and optimizations to determine the most efficient plan configuration across the subscriber base.
  • Validate cost models against carrier invoices and financial data, investigating and resolving discrepancies.
  • Monitor, forecast, and manage pooled usage and network spend, recommending corrective actions with quantified impact.
  • Model pricing and contract scenarios on actual usage data to support commercial decision-making.
  • Move recommendations into production through automated, auditable workflows and verify outcomes.
  • Design, build, and maintain underlying data models using dbt, Redshift, and related tools.
  • Use AI tooling to accelerate modeling, analysis, SQL/dbt work, and documentation.

Requirements

  • 4+ years of experience in data science, decision science, operations research, pricing/optimization, or cost analytics, ideally with recommendations carrying real financial impact.
  • Hands-on experience formulating and solving optimization problems (linear programming, cost modeling, marginal-cost analysis, or similar) that informed real business decisions.
  • Strong business judgment, with experience owning a commercial or cost recommendation end-to-end.
  • Strong SQL skills, including experience with large datasets, complex transformations, and performance optimization.
  • Proficiency in Python.
  • Experience validating analytical models against external financial data (invoices, bills, or settlements).
  • Demonstrated use of AI in day-to-day workflow, such as LLM-assisted coding or prompt-driven data exploration.
  • Strong communication skills, with a bias toward clear recommendations and measurable business impact.
