What you'll do: 🔧 Merchant onboarding: configure payment methods and routing (PSP, On/Off-ramp, cards) 🔧 API integrations: issue keys, set up environments, validate requests in Postman. 🔧 Incident investigation: trace transaction errors through JSON payloads, SQL queries, and Grafana logs to find the actual root cause. 🔧 Bug triage: reproduce, isolate (merchant vs. platform side), escalate to Engineering with a clear technical write-up. 🔧 Production go-live: final configuration checks before a merchant goes live. What you bring: 💡 You are one of two profiles: 1. Senior Customer Support in FinTech or payment processing with technical depth: you've used Postman to test requests, written SQL queries, and know your way around logs. 2. L2 Technical Support or Integration Specialist with 2+ year working directly with payment APIs, merchant configurations, or PSP integrations. 💡 Hands-on log experience - you can follow a transaction trace and find where it broke. 💡 Solid understanding of REST APIs, JSON structures, and how payment flows work end to end. 💡 English B2/C1 in writing - merchants are international. Nice to have: Grafana or similar monitoring tools, experience with PSP connectors or payment gateways, SQL well enough to write your own queries. What we offer: ✔️ Fully remote international team. ✔️ Competitive salary discussed individually. ✔️ Real ownership - you're resolving issues, not just routing tickets. ✔️ Clear path to Senior roles in Support, Product, or Engineering. ✔️ Transparent engineering culture, low bureaucracy.
