Senior Software Engineer, Billing PlatformActive$162K–$420K

The opportunity

The Billing team sits at the intersection of product, finance, and infrastructure. They're responsible for ensuring every observable event—errors, logs, traces, tokens—gets accurately measured, priced, and billed.

What you'll do

  • You will collaborate on building the next generation of Sentry’s usage: tracking pipeline, processing hundreds of billions of events daily with low latency and financial-grade accuracy.

  • You will help 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.

  • You will contribute to technical decisions on data consistency challenges: unique to billing—like handling event delays, retroactive pricing changes, and distributed count reconciliation across our infrastructure.

  • Want to solve the "easy to explain, hard to build" problems—like ensuring a: customer's bill matches their usage perfectly, even when processing hundreds of billions of events daily across distributed systems.

  • Thrive on constraints that force elegant design: financial accuracy is non-negotiable, customer trust depends on billing transparency, and the system must scale with Sentry's user and product growth without rearchitecting every year.

  • Enjoy partnering across the organization—from BizOps and sales to marketing: and leadership—where your code directly impacts ARR and your architectural decisions show up in board-level metrics.

What they're looking for

  • Built or significantly improved systems with high-stakes accuracy requirements.
  • Mentored engineers through ambiguous, high-stakes projects.
  • Operated services where reliability includes uptime and also financial correctness.
