About the Role

Employ analytical techniques to solve key business questions and produce statistical reports analyzing internet performance for Government customers.

Responsibilities

  • Lead key, cross-functional analytical projects, identifying and bringing together stakeholders/ partners, developing joint analytical approaches, and completing the project.
  • Collaborate with internal and external partners, including Data Scientists within the company and across clients, on methodology for reporting ISP performance in specific geographies and explaining data trends and patterns.
  • Develop and maintain data pipelines and dashboards to monitor and track trends and changes in customer data.
  • Use data to identify opportunities and patterns of interest to Government customers.
  • Display deep data wrangling techniques and strong visualization skills to present narratives identifying growth opportunities.

Requirements

  • Strong R for production reporting pipelines: tidyverse, multi-file project navigation, debugging across pipeline stages, and package/version management with renv.
  • SQL for analytical querying against BigQuery and MariaDB via bigrquery, DBI, and RMariaDB.
  • Literate programming and reporting: R Markdown and Quarto rendering to Word, chart/table formatting with ggplot2/flextable/officedown, and reproducible quarterly output.
  • Statistical judgment: interpreting confidence intervals, weighted means, trimmed means, and sample size limitations.
  • Report writing for a regulatory audience: clear, detailed, defensible prose with consistent terminology, informative tone, and editorial judgment.
  • Attention to detail in published outputs: catching mislabelled figures, wrong baselines, numbers that don't sum, and chart axes that obscure trends.
  • Data management across multiple systems: BigQuery, GCS, SharePoint/OneDrive, and local R sessions with no automated orchestration.
  • Comfortable using AI coding tools (Cursor, Copilot, etc.) as a force-multiplier for pipeline maintenance, debugging, drafting, and routine code changes.
  • Experience with broadband measurement, telecom/ISP data, or network performance concepts.
  • Spatial data basics in R.
  • Awareness of PII and data confidentiality constraints.
  • Shiny for small internal tools.
