We believe CX limits were meant to be shattered, and the engineers who build our platform are at the heart of making that happen. For additional information, visit www.8x8\.com, or follow 8x8 on LinkedIn, Twitter and Facebook. **About the Team** The BizApps Commerce Team owns the billing infrastructure that powers 8x8's commercial engine. We build and operate the systems that handle how customers are billed, how partners are onboarded, and how revenue flows through the business. Our work sits at the intersection of Product, Finance, and Platform engineering, and the systems we build are used every day by customers, partners, Salesforce ops, and finance teams worldwide. We work across a modern, distributed stack and ship things that matter. We move fast, we own what we build end\-to\-end, and we care deeply about correctness because in billing, a bug isn't just a bug \- it's a wrong invoice, an angry customer, or missed revenue. **The Role** We're looking for a **Staff Software Developer** who is excited about building reliable, scalable billing and commerce systems. You'll join a tight\-knit team of engineers and work directly with your engineering manager, other staff developers, tech leads, and cross\-functional partners across Salesforce, finance, and channel ops. This is a full\-stack backend\-leaning role. You'll work on real problems like customer hierarchy modeling, subscription lifecycle management, consumption based billing, tax integrations, payment integrations, billing event processing and you'll have meaningful ownership from day one. Our platform makes extensive use of Spring Boot and Spring Cloud and the stack is primarily written using Java. The technology stack is entirely owned by 8x8 which means engineers have exposure to many facets of architecture. **Responsibilities** * The position may be remote, you must be comfortable working autonomously and driving work forward in a distributed, fast\-paced engineering organization * Collaborate with cross\-functional teams (product, design, operations, infrastructure) to design and deliver reliable billing platform experiences * Architect and develop scalable backend services and APIs across the billing ecosystem including subscription lifecycle management, usage aggregation, and payment processing * Lead complex technical efforts end\-to\-end from requirements decomposition through design, implementation, and production rollout with minimal oversight * Provide technical guidance and architectural direction to engineers across the team; establish and uphold engineering standards
