Job summary

Stellar Development Foundation seeks a Backend/Systems Engineer to own the critical layer between core infrastructure and the outside world. You will design the JSON-RPC endpoints, implement the transaction lifecycle, and build the indexer and data services powering the block explorer.

You will collaborate with protocol architects to deliver production-grade infrastructure, with a focus on reliability and observability.

Qualifications

• Strong systems or backend programming experience in Rust, C++ or 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.

Responsibilities

• Public API Layer: Design and build the JSON-RPC endpoints that external tools, SDKs, and wallets use to communicate with the core network.
• Transaction Lifecycle: Own the full path from client to consensus and back, including status tracking and timeout handling.
• Indexer & Query Backend: Build the data backend powering the block explorer, partner integrations, and historical state queries.
• Data & Observability: Develop analytics pipelines and implement metrics and event logging using tools like Prometheus, Clickhouse, and Sentry.
• Cross-Functional Impact: Work across service boundaries and understand how components behave even if you don’t own them.
