On the Konnect Metering & Billing team at Kong, you'll design, build, and maintain the backend services behind two products: usage metering and billing, and AI Cost Management (Tokenomics), which gives customers visibility and control over what their AI usage costs. As a Backend Engineer, you'll work closely with Engineering and Product to build scalable services and APIs that process millions of events per second and have a direct, measurable impact on our customers.

Tasks

  • Design, implement, and maintain microservices and APIs for usage metering, billing, invoicing, and analytics at scale.
  • Build AI Cost Management capabilities that help customers track, attribute, and control LLM token usage and spend, including cost attribution, budgets, and usage limits.
  • Architect backend systems that process millions of events per second in real time.
  • Work with Product and Engineering to define system requirements and ship high-quality, customer-focused solutions.
  • Optimize database performance and ensure data integrity, reliability, and security across distributed systems.
  • Integrate with third-party services (e.g., Stripe, CRMs) to support billing and reporting needs.
  • Support production services through monitoring, troubleshooting, and on-call rotation to keep them highly available.
  • Apply best practices for DevOps, CI/CD, and cloud-native development.
  • Write automated tests to validate system behavior and prevent regressions.
  • And any additional tasks required by your manager.
