Job Level

Lead

About the role

  • Architect and build the next generation of Sentry’s usage tracking pipeline, processing hundreds of billions of events daily with low latency and financial-grade accuracy.
  • Design flexible pricing primitives that support everything from per-event usage billing to complex enterprise contracts, enabling product and sales teams to experiment rapidly while maintaining revenue accuracy and reduced time-to-market for new products.
  • Lead technical decisions on data consistency challenges unique to billing—like handling event delays, retroactive pricing changes, and distributed count reconciliation across our infrastructure.
  • Establish billing-specific engineering standards across Sentry—defining patterns for usage tracking, financial data modeling, and audit logging that other teams can adopt

Requirements

  • Built or significantly improved systems that handle financial data or high-stakes accuracy requirements—billing systems, payment processing, accounting platforms, or financial data pipelines.
  • Experience with data modeling — distilling complex business problems into elegant, maintainable schemas
  • Mentored engineers through ambiguous, high-stakes projects where technical decisions have direct revenue implications.
  • Operated services at Sentry’s scale (millions of events per second) where reliability includes uptime and also financial correctness.
Benefits
  • A successful candidate will be eligible to participate in Sentry’s employee benefit plans/programs applicable to the candidate’s position (including incentive compensation, equity grants, paid time off, and group health insurance coverage).
