Ruby Labs is a leading tech company that creates and operates innovative consumer products. We're looking for a Lead Billing Data Analyst (Billing, Payments & Subscription Analytics) to own the data strategy behind our subscription billing operations. This is a hands‐on leadership role: you'll build analyses and pipelines that improve billing performance, while also managing and mentoring a team of analysts.
Monitor, analyze, and report on billing and support performance metrics (payments, renewals, refunds, disputes/chargebacks), and surface emerging trends.
Build and maintain data pipelines that deliver accurate, timely, and reliable billing data.
Apply statistical methods to model scenarios, run "what-if" analyses, and anticipate financial risk.
Design and run A/B tests and experiments to evaluate billing and support initiatives.
Analyze the impact of product, marketing, and pricing changes on billing outcomes, risk behavior, and customer support metrics.
Build and maintain dashboards and visual reporting that provide clear,



real‐time visibility into billing health and support performance.
Document analyses, workflows, definitions, and data logic to ensure clarity, reproducibility, and consistency.
Lead, mentor, and grow a team of data analysts: set expectations, coach on methodology, and ensure high‐quality output.
Uplevel the team's billing domain knowledge and analytical/technical skills.
Partner cross‐functionally with Billing, Support, Finance, Product, and Marketing to align metrics, definitions, and processes with risk‐mitigation goals.
Deep subscription billing expertise : substantial experience with payments, renewals, refunds, disputes/chargebacks/TC40 in a recurring-revenue business (non‐negotiable).
Advanced SQL : complex joins, window functions, incremental logic, and performance‐aware query writing.
Data visualization : proficiency with Omni, Tableau, Power BI, or similar tools to build dashboards and communicate insights clearly.
