- 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
- 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
Our recruitment process typically follows these stages:
- Interview Stages (2-3 weeks):
- Prescreening call (40 min)
- Technical Interview (60 min)
- Soft Skills Interview (40 min)
- Competitive compensation package (commensurate with your experience)

- Opportunity to regularly participate in conferences and community events as both a participant and contributor
- Matrix organizational structure designed to streamline communication, remove barriers, and promote efficiency
