Senior Backend Engineer (Billing)
Posted Updated
- 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

- Experience decomposing a monolith
- 6+ years of professional software-engineering experience, with significant work on complex backend applications
- A track record on systems where correctness is non-negotiable, and the habits that come with it: idempotency, reconciliation, reversible migrations, and safe cutovers
- Proficiency in at least one backend language (Go, Rust, Python, etc.) and familiarity with cloud infrastructure (AWS or equivalent), plus strong production ownership including on-call
- Modeling entitlements, quotas, or multi-tenant limits
- Billing, payments, or metering systems, or usage-based pricing
