Develop and maintain backend systems for blockchain data ingestion, indexing, storage, and API serving to ensure data correctness, freshness, and query performance.
О компании
- is the Web3 infrastructure and developer platform that powers millions of users and the world’s most innovative blockchain applications. From enabling $1+ trillion in financial transactions worldwide to scaling L2s and enabling DeFi, provides the infrastructure and tools developers need to build reliable, scalable, and accessible experiences.
- Trusted by companies like JPMorgan, Stripe, Visa, Franklin Templeton, Nike, and backed by a16z, Coatue, Silver Lake, Lightspeed, and Stanford University, is building the foundational layer for a decentralized and AI-enabled Web3 ecosystem. For more information, visit .com .
Обязанности
- Build the systems that turn blockchain activity into data developers can use. ’s Data Services work includes token, portfolio, and transfer APIs, with streaming in the updated roadmap.
- You will own backend projects from ingestion through serving, making data correct, fresh, and fast to query. You will work with Product and customer-facing teams to understand what developers need, then ship improvements and measure their effect on reliability, performance, and cost.
- Build and operate blockchain ingestion, indexing, storage, and API-serving systems.
- Handle reorganizations, retries, duplicate events, and historical backfills without silently losing or corrupting data.
- Improve query performance and data freshness. Make those properties observable to the team and understandable to customers.
- Extend API capabilities and chain coverage, with tests for differences in chain behavior and data semantics.
- Develop streaming and event-delivery capabilities with explicit guarantees for ordering, replay, and failure recovery.
- Reduce the cost of storing, processing, and serving data through measured changes to architecture and query execution.
- Participate in production support and incident response for the systems you own. Maintain monitoring, runbooks, safe rollouts, and fixes that prevent recurrence.
- Within three months:
- You have shipped a customer-facing improvement and can show its effect on data quality, freshness, latency, or cost.
- You own a production component, have tested its recovery behavior, and have proposed the next improvement using operational evidence and developer feedback.
Требования
- A track record of independently designing, shipping, and operating production backend or distributed data systems.
- Strong programming skills in a production backend language, plus experience with databases, indexing, and query performance.
- Experience reasoning about consistency, partitioning, asynchronous processing, and failure recovery.
- Evidence that you can diagnose a production problem and improve the system beyond the immediate fix.
- Sound API design judgment, including compatibility, pagination, error handling, and data contracts.
- Clear communication and the ability to turn an ambiguous customer problem into a scoped engineering project.
- Blockchain experience is helpful, but not required. You should be interested in learning how chain behavior affects data correctness.
