Senior Software Engineer (Billing Platform)

Join Sentry as a Senior Software Engineer and play a key role in architecting and scaling the core systems that power our billing infrastructure. You will collaborate on building the next generation of Sentry’s usage tracking pipeline, design flexible pricing primitives, and contribute to technical decisions on data consistency challenges unique to billing. Enjoy competitive compensation, equity, and a range of benefits including medical, dental, and vision insurance, a 401k plan, and flexible PTO.

• 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.

• Built or significantly improved systems with high-stakes accuracy requirements
• Mentored engineers through ambiguous, high-stakes projects

• 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
• 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
• Operated services where reliability includes uptime and also financial correctness
