About the role
As a PHP Developer focused on anti-fraud systems, you will take deep technical ownership of designing, building, and maintaining fraud detection and prevention workflows.

- Build and maintain anti-fraud orchestration, scoring, and decision-making logic within complex systems
- Make independent technical decisions on where and how to integrate SEON checks across business flows
- Develop reliable, idempotent, and transactional systems featuring retries, fallbacks, and event-driven architecture
- Ensure observability across the anti-fraud layer through robust logging, tracing, and monitoring
What you bring
- 4+ years of commercial software engineering experience with PHP and modern frameworks such as Symfony
- Solid hands-on experience integrating SEON API, device intelligence, and enrichment into production systems
- Proven background building antifraud, risk, or security-related flows and handling complex domain logic
- Strong understanding of REST APIs, webhooks, asynchronous processing, queues, and SQL transactional systems
- Ability to work independently with external provider documentation in an ambiguous environment
