About the role

Key responsibilities & impact

Public API Layer: Design and build the JSON-RPC endpoints that external tools, SDKs, and wallets use to communicate with the core network (transaction submission, status queries, account state).
Transaction Lifecycle: Own the full path from client to consensus and back. Status tracking, error reporting, and timeout handling.
Indexer & Query Backend: Build the data backend that powers the block explorer, partner integrations, and historical state queries.
Data & Observability: Build out analytics pipelines (e.g., BigQuery population) and implement robust metrics and event logging using tools like Prometheus, Clickhouse, and Sentry.
Cross-Functional Impact: Work across service boundaries, getting comfortable reading code in components you don't own to understand how they behave.
