About the role

Key responsibilities & impact

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).
Own the full path from client to consensus and back. Status tracking, error reporting, and timeout handling.
Build the data backend that powers the block explorer, partner integrations, and historical state queries.
Build out analytics pipelines (e.g., BigQuery population) and implement robust metrics and event logging using tools like Prometheus, Clickhouse, and Sentry.
Work across service boundaries, getting comfortable reading code in components you don't own to understand how they behave.

Requirements

What you’ll need

Strong systems or backend programming experience in Rust, C++ or both (our codebase uses both).
Proven track record of designing and building robust RPC/API services that handle real-world, high-scale traffic.
Deep understanding of database architecture, indexing, and query patterns.
You are a builder who takes ownership of production infrastructure, not just prototypes.
Prior experience building or operating blockchain infrastructure (nodes, RPC layers, indexers) in production (optional).
Experience with a testnet or mainnet launch (optional).
