About the role
- Establish and enforce security architecture for digital transactions using recognized frameworks, tokenization, and hardware-backed key management with validated cryptographic modules.
- Set the reliability engineering program for APIs and event pipelines by defining SLIs/SLOs, implementing error-budget governance, standardizing runbooks and chaos/resiliency tests, and improving health.
- Verify program logic by preparing representative test data and executing trial runs in lower/UAT environments.
Responsibilities
- Lead the architecture and operation of 24×7×365, low-latency services with documented availability objectives and continuous operations patterns including active-active, automated failover.

- Own API spec governance for synchronous HTTP and asynchronous events-compatibility rules, deprecation policy, and contract/conformance tests.
- Drive performance engineering for high throughput, low latency services through partitioning, indexing, memory/GC tuning, and hot path optimizations.
- Lead structured data migration and interoperability with mapping guides, reconciliation controls, and cutover/rollback plans.
