Ranked #2 in the “Employer of the Year 2026” award by Forbes Ukraine. ## ABOUT THE TEAM AND ROLE You'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.

Design and ship the foundational Products & Prices domain model and public APIs from scratch. - Complex B2B Pricing at Scale. Build high-precision volume and graduated pricing engines for multi-tier enterprise billing. - 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. We rely on automated testing over manual QA — unit, integration, functional, and e2e tests are a core part of how we ship and scale safely.
