About the Role

- Improving observability across payout → processor → bank flows
- Eliminating recurring payment bugs at the root cause
- Reducing manual treasury overhead
- Abstracting processor dependencies
Requirements
- 6+ years in building scalable backend systems, with a strong preference for experience in high-stakes domains such as payments, fintech, billing, or financial infrastructure.
- 3+ years of industry experience in backend/platform engineering (or equivalent), including ownership of production systems.
- Demonstrated ability to integrate with and manage third-party payment gateways (e.g., Stripe, Adyen) and/or direct banking APIs.
- Understanding of financial regulations, including adherence to PCI-DSS, and the secure handling and encryption of sensitive banking and customer data.
- 3+ years of professional experience building around transactional databases like MySQL or PostgreSQL.
- 3+ years of professional experience building around compiled languages like Go, Rust, or C++.
- Experience with message queues or streaming platforms (e.g., RabbitMQ, SQS, Kafka).
- Experience with distributed systems frameworks like temporal, k8s, etc..
- Proven ability to manage and operate production systems under significant load.
