Multi-chain indexing

Descripción de la vacante

Aether Protocol is seeking a backend-focused engineer to build off-chain systems that index events, expose APIs, and monitor protocol health from a remote location in the United States. You will work with Solidity engineers to ensure contract events align with off-chain consumers and operate safe, observable services.

Responsibilities include designing indexing and API services for core protocol components, handling failures gracefully, and documenting deployment context for reliable operations.

Formación

• Strong backend experience with TypeScript/Node.js or equivalent service stacks.
• Experience with blockchain indexing, RPC providers, or event-driven data pipelines.
• Comfort designing for failure: retries, idempotency, stale reads, and partial outages.
• Ability to model APIs around on-chain state and make pending/confirmed behavior explicit.
• Clear collaboration habits with protocol and product engineers.

Responsabilidades

• Design and implement indexing and API services for Hub, AeToken, liquidation, and incentive events.
• Integrate privileged oracle and operational data flows with staleness and failure handling.
• Build monitoring, alerting, and reconciliation paths for RPC outages and missed events.
• Partner with Solidity engineers so contract events and off-chain consumers stay aligned.
• Document runbooks and deployment context for operating Aether-related services safely.

Descripción del empleo

Aether Protocol Full-time · Contract United States · Remote

Build the off-chain systems around Aether Protocol—event indexing, APIs, monitoring hooks, and reliable data paths that keep protocol state visible and operable.

Aether’s contracts need a production-minded backend layer: indexing market events, exposing application APIs, reconciling chain state after reorgs or RPC failures, and giving operators clear visibility into protocol health.

Responsibilities

• Design and implement indexing and API services for Hub, AeToken, liquidation, and incentive events
• Integrate privileged oracle and operational data flows with staleness and failure handling
• Build monitoring, alerting, and reconciliation paths for RPC outages and missed events
• Partner with Solidity engineers so contract events and off-chain consumers stay aligned
• Document runbooks and deployment context for operating Aether-related services safely

• Clear collaboration habits with protocol and product engineers

Nice to have

• Experience supporting DeFi dashboards, keepers, or liquidator infrastructure
• Familiarity with Postgres, queues, and observability tooling in production
• Prior work on multi-chain or L2 indexing systems
