Founded in 2021, LiveKit powers voice AI applications for OpenAI, xAI, Salesforce, Coursera, Spotify, and thousands of others, collectively facilitating billions of calls each year.
About This Role:
Most companies hire someone to maintain a billing system. We need someone to rebuild one - and that's a meaningfully different job. You're an engineer first. You can write the integrations, own the infrastructure, and wire up the systems - not just configure drop downs in a UI. But you also understand that your real customers are in Finance and RevOps, and you take data accuracy as seriously as uptime.
You'll thrive as a Staff Billing Systems Engineer if you:
obsess with crafting code that is fast, reliable and practical for the problem
are known as the go-to person for tackling tough technical problems
work hard and can build and ship fast
can clearly explain complex technical concepts to others
are a fast learner, frequently picking up new languages and tools
The best way to impress us is with thoughtful Issues and/or PRs on our Github repos 😊
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
We offer
The opportunity to shape the brand of a fast-growing developer platform
Collaboration with a small, senior team that deeply values craft and creativity
Competitive salary and equity package
