Payment orchestration: Design, build and run high-throughput backend services that orchestrate crypto pay-ins, pay-outs, conversions and transfers across many assets and blockchain networks.
API design: Build and evolve clean, versioned, well-documented public and internal APIs that merchants and partners use to accept, convert and send money.
Reliability and correctness: Make sure every payment is processed exactly as intended. Use proven patterns such as idempotency, transactional outbox, retries and dead-letter handling so financial events are never lost or duplicated.
Performance and scalability: Find and fix bottlenecks in hot paths, database access and service-to-service calls, so the platform scales with fast-growing payment volumes.
Platform evolution: Help modernise our core services by breaking up legacy components into clear, modular, domain-aligned boundaries, while keeping a live payments platform running safely.
Event-driven architecture: Design and build asynchronous, event-driven workflows with clear contracts between our services and other domains.
Cross-team collaboration: Work closely with Product, other engineering teams, Compliance and Operations to deliver new payment capabilities, assets and networks end to end.
Operational excellence: Own your services in production. Monitor, alert, take part in on-call, and lead incident response and root cause analysis that leaves our systems stronger.

Bonus: Digital assets: Experience with stablecoins, blockchain networks, crypto wallets or crypto payment processing.
Bonus: Domain-driven design: Experience applying domain-driven design, modular architecture or large-scale refactoring of legacy services.
