Your mission

We’re looking for a Systems Analyst to own the technical analysis and end-to-end design of payment provider integrations.

You’ll work hands-on with API ecosystems, deconstruct complex provider documentation, define transaction flows, and turn specs into real, live payment products.

Analyze and map payment provider APIs and endpoints
Design end-to-end payment flows and integration blueprints
Translate business and customer needs into clear technical requirements
Own PRDs, backlog definitions, and validation with engineering teams
Lead testing and operational readiness before launch

Your profile

Proven experience in system analysis or technical product roles within payments, fintech, or financial services
Hands-on experience working with REST APIs, Swagger/OpenAPI, and tools like Postman or Insomnia
Strong understanding of payment flows, webhooks, callbacks, and real-time notifications
Comfortable working with JSON/XML, system diagrams, and sequence flows
Experience documenting requirements and managing backlogs using Jira & Confluence
Strong communication skills to work with internal teams and external providers
English is mandatory
Ukrainian (or Russian), Spanish or Portuguese is a plus
