• Manage operational communication with PSPs, banks, gateways, acquirers, and crypto processing partners.
• Configure and optimize payment orchestration logic in Praxis Tech, PaymentIQ, or similar platforms (routing, cascading, failover, limits, provider rules).
• Support launches of new payment methods, providers, currencies, and GEO-specific cashier setups.
• Coordinate investigations of settlement failures, missing callbacks/webhooks, stuck payouts, and other technical payment issues together with the IT team.
• Monitor provider performance and recommend improvements to approval rates, reliability, and cost efficiency.
  
   

Risk, Fraud, and Crypto Controls
 

• Monitor payment activity and player behaviour for fraud patterns, including multi-accounting, bonus abuse, account takeover, payment-method abuse, and withdrawal fraud.
• Participate in developing fraud-detection methodologies, risk policies, velocity checks, approval tiers, and escalation logic.
• Monitor crypto transactions using tx hashes, block explorers, wallet-screening and transaction monitoring tools; investigate crypto-processing issues.
• Support dispute and chargeback handling for non-crypto payment methods where applicable.
  
   

Customer Communication and Support
 

• Communicate with players via email and Customer Support channels regarding payment related issues.
• Define and maintain workflows between Payments, Customer Support, PSPs, and other internal teams.
• Train Customer Support teams on payment-related cases and escalation procedures.
  
   

Process Design and Reporting
 

• Participate in building payment operations processes and internal documentation.
• Define requirements for risk-management tools and services for the IT team.
• Prepare management reporting on payment performance, fraud trends, incidents, and operational KPIs.

Identify workflow gaps, propose process improvements, and participate in incident reviews and root-cause analysis.

Requirements

• Previous experience in payments operations/antifraud/risk in iGaming or similar operations.
• Experience with crypto processing, crypto cashier operations, or blockchain-based payment flows.
• Solid understanding of payment flows across cards, bank transfers, e-wallets, PSPs, and alternative payment methods.
• Strong Excel skills and confidence working with reconciliations, operational reporting, and transaction-level data.
• English level - C1.

Preferred Qualifications

• Strong mathematical background and analytical mindset.
• Practical understanding of crypto operations, including block explorers, wallet screening, sanctions exposure, network fees, congestion, and wrong-network/wrong-memo scenarios.

Ми — швидкозростаюча фінтех-компанія, і шукаємо людину, яка візьме повний цикл роботи з клієнтською базою у свої руки. Не виконавця завдань, а власника напряму: від стратегії до цифр на дашборді.

— Розробляти стратегію «дожиму» на всіх етапах воронки: від покинутої заявки до реактивації лояльних клієнтів
— Сегментувати базу в CRM за тригерами: давність останнього входу, кількість закритих кредитів, час без контакту
— Налаштовувати тригерні ланцюжки та проводити ручні розсилки — акційні пропозиції, тестування гіпотез
— Регулярно оновлювати шаблони та альфа-імена, щоб комунікації не «вигорали»
— Відстежувати ефективність на кожному кроці: від доставки повідомлення до цільової конверсії

КОГО МИ ШУКАЄМО:
— 2+ роки на позиції CRM / Retention / Lifecycle Manager — бажано у Fintech, МФО або iGaming

— Рахуєш конверсію і робиш висновки — не просто «дивишся на цифри»
— Когорти, A/B тести та аналітичні дашборди — твій звичний інструментарій

МИ ПРОПОНУЄМО:
— Продукт, що реально росте, з вибудуваними процесами — і простір, щоб на них впливати
— Повна автономія та відповідальність за CRM / Retention: твій напрямок, твої рішення
— Швидкі рішення без бюрократії — ідею можна перевірити вже наступного тижня
— Гібридний формат роботи з гнучким графіком
