Job summary

LaunchDarkly in Oakland, CA is seeking a Senior Backend Engineer for the Billing team who will own the systems turning plans, pricing, entitlements, and usage limits into revenue through checkout, subscriptions, invoicing, and metering.

You will decompose the billing monolith into services, ensure correctness and deployability, own end-to-end accuracy, and operate with SLOs and on-call responsibilities.

Qualifications

• 6+ years of professional software-engineering experience, with significant work on complex backend applications.
• Experience decomposing a monolith
• 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.

Responsibilities

• 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.
