What you'll do
- Manage the full onboarding cycle for new payment providers, including initial technical calls, credentials and sandbox access, configuration and test design, User Acceptance Testing (UAT), production launch, and post-release stabilisation
- Define integration acceptance standards and own the go/no-go decision before launch
- Review provider API documentation and translate it into implementation-ready specifications for engineering, covering edge cases, failure paths, and confirmation model behaviour
- Own the first-line response for payment incidents, including failed and stuck transactions, unconfirmed payments, and payment method-level anomalies
- Investigate and drive incidents to resolution rather than simply escalating them
- Diagnose provider-side versus platform-side issues using logs, API responses, and transaction data
- Communicate findings clearly to providers, engineers, and internal stakeholders
- Perform hands-on verification of payment integrations
- Conduct manual checkout testing across mobile and desktop
- Verify callbacks and API behaviour using Postman or equivalent tools
- Execute SQL queries to investigate transaction data
- Validate asynchronous payment statuses, confirmation models, redirect flows, and failure scenarios
- Maintain a comprehensive catalogue of payment methods and providers, documenting supported capabilities, available integration types, completed testing, and known failure modes
- Build the initial capability inventory of all live payment methods and providers
- Convert ambiguous provider documentation and undocumented operational knowledge into actionable specifications
- Produce a 90-day breakdown of deposit attempts, categorised by outcome: completed transactions, declined by the provider, abandoned by the user, abandoned during redirect, and completed but never confirmed back to the platform
What we're looking for
- 4+ years of experience in payments, PSP integrations, or fintech platforms, with hands-on ownership of integrations rather than coordination alone
- Working knowledge of APIs, webhooks, asynchronous payment statuses, callback mechanics, confirmation models, redirect flows, and common failure modes
- Ability to review provider API specifications and identify missing information
- Experience using Postman or equivalent tools for API testing
- Experience performing structured checkout testing across mobile and desktop
- Proven ability to investigate live payment incidents using logs and API responses
- Ability to distinguish provider-side issues from platform-side problems
- Experience translating incomplete or ambiguous technical documentation into clear specifications for engineering
- Strong communication skills and composure during incidents
- Basic knowledge of using AI tools in daily work
- Working proficiency in both English and Russian, as both languages are used daily
Nice to have
- Experience with Alternative Payment Methods (APMs) and local payment rails across Asia, Africa, or LATAM, beyond card payments
- Knowledge of bank transfer rails, virtual accounts, QR-based payments, mobile money, and similar payment methods
- Background in brokerage, crypto payments, payment orchestration, or other high-volume payment environments
- Previous experience working with a PSP, payment gateway, or payment provider
- Active use of AI tools in daily workflows
- Ability to work independently and make decisions without constant supervision
- A proactive approach to identifying improvements, proposing solutions, and implementing new processes
