Billing Systems Engineer

What You'll Do

• Own the end-to-end billing system overhaul — CPQ configuration, quote-to-cash integration, billing platform wiring, ERP sync, and everything in between
• Design and build the integrations that connect LiveKit's product usage events to our billing platform, ensuring metered and consumption-based billing is accurate and auditable
• Establish change control, deployment practices, and audit trails for all billing-critical systems under your ownership
• Partner closely with Finance, RevOps, and Analytics to define data contracts and validate that billing outputs are correct — every time
• Build systems that can absorb pricing model changes, new product lines, and volume growth without requiring heroic one-off engineering

Who You Are

• Hands-on experience building integrations across CPQ, billing platforms (Metronome, Orb, Chargebee, or similar), and ERP systems — not just configuring them, but engineering the data flows between them
• Familiarity with quote-to-cash workflows and where they break in practice
• Treat billing-critical systems like production infrastructure: version-controlled, tested, deployed through a proper CI/CD pipeline, and monitored with observability tooling
• Strong change management discipline — you think in terms of safe deploys, rollback strategies, and audit trails, not just "push and see"
• Comfortable owning systems under Finance-grade accuracy requirements, with the rigor to back it up
• Strong enough technically to build and maintain the integrations yourself, strong enough cross-functionally to be a trusted partner for Finance and RevOps stakeholders
• Experience with usage-based, consumption, or event-driven billing models

Nice to Have

• Prior greenfield billing system build — you've designed one, not just inherited one
• Familiarity with modern usage-based billing platforms like Orb or Metronome
• You're the person who actually checks whether the numbers are right — not because someone asked, but because wrong data keeps you up at night
