Sentry is an application monitoring platform trusted by 200,000+ organizations. The company helps developers fix errors and performance issues before users notice, enabling teams to spend less time firefighting and more time building.
The Billing team sits at the intersection of product, finance, and infrastructure. They are responsible for ensuring every observable event—errors, logs, traces, tokens—gets accurately measured, priced, and billed. This work directly impacts company revenue and customer trust, requiring distributed systems expertise, attention to financial accuracy, and deep understanding of product usage patterns.
As a Senior Software Engineer on the Billing Platform team, you will architect and scale the core systems that power Sentry's billing infrastructure, ensuring accuracy and reliability at massive scale. 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—such as handling event delays, retroactive pricing changes, and distributed count reconciliation across the infrastructure.
This role is ideal if you want to solve "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
