We are looking for a Project/Product Manager with hands-on experience in PSP, payment processing, and payment integrations. This is not a general Project Manager role. We need someone who understands how a new payment provider integration works end-to-end — from API documentation and sandbox setup to testing, production launch, and troubleshooting. WHAT WILL YOU DO - Lead integrations with new PSPs, payment providers, and payment methods. - Review API documentation and understand the full integration flow. - Break integrations down into clear tasks for Development and QA. - Coordinate credentials, environments, merchant configuration, dependencies, and blockers. - Work closely with developers, QA, business stakeholders, and external payment providers. - Oversee testing, production launch, and post-release stabilization. - Manage the backlog in Jira, including Epics, Tasks, dependencies, priorities, and Jira Plans. - Plan timelines and team capacity. - Maintain clear documentation in Confluence. - Help prioritize payment integrations and payment methods. MUST-HAVE EXPERIENCE Hands-on experience with: - PSP / payment gateway / acquiring / payment processing. - Payment provider integrations. - REST APIs and request / response logic. - Webhooks / callbacks. - Authentication, signatures, and API keys. - Deposits / payouts. - Transaction statuses and status mapping. - Sandbox / staging / production environments. - Error handling and integration troubleshooting. - Reconciliation and basic financial flows. You should have personally participated in payment integrations from provider documentation through production, not only managed teams at a high level. STRONG ADVANTAGES - iGaming / betting / crypto / forex payments. - Payment orchestration and routing. - Experience managing multiple PSP integrations simultaneously. - International payment integrations. - Settlements, fees, and reconciliation. - AI tools for analysis, documentation, or project management. NOT A FIT - General IT Project Managers without a PSP / payments background. - Fintech PMs whose experience is limited to mobile banking, CRM, or lending. - PMs who cannot independently explain a payment lifecycle and integration flow. - Candidates with theoretical payment knowledge but no hands-on integration launches. WHAT WE OFFER - Fully remote work. - Hands-on exposure to international payment infrastructure. - A large number of PSPs, payment methods, and integrations. - High level of ownership and direct influence on product and delivery. When applying, please briefly mention which PSPs / payment providers you have worked with, which integrations you personally launched, your role in the integration process, and your availability.
