Blockchain & Wallet Operations
- Ensure safe and rapid crypto delivery (e.g., USDC/SOL) to user wallets by managing hot‑wallet flows, transaction creation, confirmations, and operational safeguards.
Reliability & Instrumentation
- Set the bar for reliability: implement SLOs, circuit breakers, retries/backoffs, dead‑letter queues, shadow traffic, and canary releases for all high‑risk financial flows.
- Instrument everything with traces, metrics, and logs.
- Build internal ops & compliance dashboards and participate in the production on‑call rotation for our 24/7 system.
