Senior Software Engineer, Billing Platform

Details

Software runs the world and the pace is faster than ever. Sentry helps developers fix errors and performance issues before users notice, so teams can spend less time firefighting and more time building.

About the team

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. Their work directly impacts company revenue and customer trust, requiring distributed systems expertise, attention to financial accuracy, and deep understanding of product usage patterns. The team works cross-functionally with product, engineering, BizOps, marketing, and sales to build systems that enable new products and pricing models.

Responsibilities

• Architect and scale the core systems that power Sentry's billing infrastructure, ensuring accuracy and reliability at massive scale.
• 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.
• 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.
• Contribute to technical decisions on data consistency challenges unique to billing—like handling event delays, retroactive pricing changes, and distributed count reconciliation across infrastructure.

You'll love this job if you

• You 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.
• You 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.
• You 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.

Requirements

• 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.
