- Interact closely with various teams (Legal, Finance, Fraud/Payment Ops) to synchronize efforts, gather requirements, and assess cross-team impacts.
- Act as a mentor and guide for mid-level (IC3) developers within the squad, elevating the team's overall engineering standards.
- Participate in a cyclic on-call duty (approximately 1 week every 7 weeks) to ensure the high availability of our critical payment systems.
