Senior Backend Engineer (Billing)

• Software powers the world, and LaunchDarkly empowers teams to deliver and control it safely
• As a Senior Backend Engineer on the Billing team, you will own the systems that turn every plan, price, entitlement, and usage limit into revenue — checkout, subscription and entitlement APIs, usage metering, and the integrations to our billing, CRM, and finance systems
• When billing is wrong, customers get the wrong product and we invoice the wrong amount. Correctness here is a commitment to our customers, not a nice-to-have. You and your team will drive the modernization of our billing platform
• Design and build the systems that define our plans, pricing, entitlements, and limits, and expose them through our API
• Decompose billing from our monolith into services that are correct, testable, and independently deployable
• Own correctness end to end — usage metering, reconciliation, and the invoices and usage data customers see
• Operate what you build: SLOs, alerting, on-call, and fixing root causes rather than repeating mitigations

• Modeling entitlements, quotas, or multi-tenant limits
• Billing, payments, or metering systems, or usage-based pricing
