## About the Role

* 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.

## Description

Own and modernize billing systems: define plans, pricing, entitlements, usage metering, and billing APIs. Decompose monoliths into independently deployable services, ensure end-to-end correctness (reconciliation, idempotency), operate SLOs/alerting, and run on-call. Integrate with billing, CRM, and finance systems.

About the Job:

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. Technologies include Go, TypeScript, Postgres, AWS, and Terraform. Exact tool match matters far less than deep backend judgment and a track record of safely changing systems that are not allowed to be wrong.
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.
