• Design and implement fraud detection and prevention flows
• Work with risk signals, rules, scoring, and decision-making logic
• Build and maintain anti-fraud orchestration within complex systems
• Make independent technical decisions on how and where to integrate SEON checks
• Understand the difference between simple provider integration and building a full fraud-control layer

Strong understanding of:

• Asynchronous processing
• Queues and event-driven architecture
• Transactional consistency
• Retry / timeout / fallback patterns
• Idempotency
• Observability (logging, tracing, monitoring)
• Experience with Symfony or another modern PHP framework
• Good knowledge of SQL and transactional systems
• Ability to work with external provider documentation and turn it into production-ready solutions
• Ability to work independently in environments with incomplete requirements and complex domain logic
  
  

SEON-Specific Experience (Required)

• Integration of SEON API into critical business flows
• Experience with transaction screening, device intelligence, and email/phone/IP enrichment
• Building logic based on SEON rules, scoring, and signals
• Working with manual review and case management flows
• Experience integrating SEON in fintech / payments / high-risk environments
• Ability to adapt SEON to different use cases beyond basic integration
• Understanding how to reduce false positives / false negatives through proper system design
  
  

Nice to Have

• Experience in fintech, payments, acquiring, wallets, or payouts
• Experience integrating KYC / AML providers
• Experience building risk engines or orchestration layers
• Experience with microservices architecture
• Knowledge of DDD, CQRS, and event-driven architecture
• Experience with RabbitMQ, Kafka, or SQS
• Understanding of authentication, identity, trusted devices, and SCA / step-up verification
