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.
