About the Team and RoleYou'll join the Billing team and become part of the effort behind one of the product's core modules — the one responsible for the invoicing cycle, payment retries, subscription management, and monetization. The team is actively building Billing v2 — a global overhaul and expansion of the subscription infrastructure — and has recently grown into a full-fledged Billing Stream.
There's no legacy here — the team is building and launching the new Billing 2.0 module practically from scratch.
Your team — 1 PM, 2 Senior Engineers, 1 Automation QA, 1 Domain Analyst.
What you'll ownCore Domain & Public APIs. Design and ship the foundational Products & Prices domain model and public APIs from scratch.

Bulletproof Platform Uptime. Decouple critical services from the Products API to eliminate single points of failure.
End-to-End Revenue Recovery. Lead the automated retry engine across all invoices, recovering millions in failed payments.
