👩🏻‍💻 **Role: Technical Support Specialist / Integration Manager
💰 Product: **B2B payment infrastructure — PSP integrations, on/off-ramp, card processing
📍 Remote | Full-time

If you can tell why a transaction got stuck on the provider side, read JSON and logs faster than you can explain what went wrong, please keep reading.

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.

📩 Apply if you genuinely enjoy figuring out why a payment failed, and seeing it through to resolution.
