As the Lead Blockchain Payments Engineer, you will be a core architect and owner of the essential financial infrastructure. You will design and scale the core services that power seamless fiat crypto flows, real-time risk decisions, and rock-solid financial records.

Design and implement idempotent, fault-tolerant APIs and robust webhook processing systems. Integrate and manage third-party providers for connectivity (Plaid/TrueLayer/Tink), card processing, and on-chain risk/compliance (Chainalysis/TRM, Travel Rule networks).
- Real-Time Risk & Compliance: Build and scale a real-time risk engine (≤ 300ms) combining ML scores, rules, device signals, sanctions/KYC hits, payment intelligence, and blockchain analytics to yield fast GREEN/AMBER/RED outcomes. Implement foundational KYC/AML primitives (CIP/CDD, sanctions/PEP screening, Travel Rule data plumbing) in close partnership with our Compliance team, ensuring audit-ready decision journaling.
- Financial Integrity & Reconciliation: Ship a double-entry ledger and automated reconciliation jobs that accurately tie together processors, bank statements, and on-chain balances. Develop daily break detection and automated remediation workflows to maintain financial integrity.
- 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.
- Cross-Functional Collaboration: Work closely with Product, Mobile, Compliance, Risk, and Finance teams, driving features from initial concept through production deployment and iteration.
