About the Role

We’re looking for a Senior or Lead Data Analyst with deep experience in subscription billing analytics and strong technical skills in ClickHouse (and ideally Tinybird). You will own analytics for billing and payments: build and optimize datasets and queries, define billing metrics, and deliver dashboards that product, finance, and operations teams rely on daily.

Key Responsibilities

  • Build and maintain data pipelines in Tinybird and ClickHouse to power dashboards and self‑serve analytics.
  • Optimize ClickHouse queries for performance, correctness.
  • Design and maintain core billing metrics: gross/net revenue, refunds, chargeback rate, dispute rate, approval rate, churn, LTV, MRR/ARR, and cohort retention.
  • Create and iterate on dashboards/visualizations for internal stakeholders (Billing/Finance/Product/Support/Risk).
  • Investigate anomalies and data‑quality issues (e.g., spikes in refunds, rising dispute rates, drops in approval rates), perform root‑cause analysis, and propose actions.
  • Partner with engineering on data instrumentation and event tracking to ensure high‑quality billing data.
  • Document logic (metric definitions, tables, pipeline behavior) and establish quality checks (tests/monitoring).

Qualifications

  • Strong subscription billing experience is mandatory (payments + renewals + refunds + disputes/chargebacks).
  • Advanced SQL (complex joins, window functions, incremental logic, performance‑aware query writing).
  • Production experience with ClickHouse: query tuning and data modeling for analytics workloads.
  • Experience building basic ETL/ELT pipelines (scheduling, incremental loads, validation, monitoring).
  • Git workflow (PRs, code review, versioning of SQL/data logic).
  • Strong experience building dashboards and visualizations (BI tools or internal dashboards) with a focus on business clarity and metric correctness.
  • Ability to communicate findings clearly to both technical and non‑technical stakeholders.

Nice to have

  • Tinybird experience (pipes, endpoints, materializations, performance tuning).
  • JavaScript (dashboard integrations, or data apps).
  • Python (for analysis/automation), dbt, Airflow (or other orchestration).
  • Experience in risk/fraud analytics.
  • Experience with experimentation/A/B tests.

Location

Ruby Labs operates within the CET (Central European Time) zone. Applicants from any country are welcome to apply for the position as long as they are located within approximately ± 4 hours of CET. This ensures optimal collaboration and communication during working hours.

Benefits

  • Remote Work Environment: Work from anywhere, anytime, promoting a healthy work‑life balance.
  • Unlimited PTO: Unlimited paid time off to recharge.
  • Paid National Holidays: Paid time off on national holidays.
  • Company‑provided MacBook: Apple MacBook provided to employees who need one.
  • Flexible Independent Contractor Agreement: Benefits of flexibility, autonomy, and entrepreneurial opportunities.
