    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.
