Senior Software Engineer (Data Services)

Join Alchemy, a leading blockchain development platform, as a Senior Software Engineer (Data Services). In this role, you will build and operate systems that turn blockchain activity into usable data for developers. You will own backend projects from ingestion to serving, ensuring data is correct, fresh, and fast to query. You will work closely with product and customer-facing teams to understand developer needs and measure the impact of your improvements on reliability, performance, and cost.

- Concevoir, expédier et exploiter des systèmes d'ingestion, d'indexation, de stockage et de service d'API pour la blockchain. - Améliorer la performance des requêtes et la fraîcheur des données, et rendre ces propriétés observables pour l'équipe. - Participer au support de production et à la réponse aux incidents pour les systèmes dont vous êtes responsable.

- Evidence that you can diagnose a production problem and improve the system beyond the immediate fix - Experience reasoning about consistency, partitioning, asynchronous processing, and failure recovery - Blockchain experience is helpful, but not required. You should be interested in learning how chain behavior affects data correctness - 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 - Clear communication and the ability to turn an ambiguous customer problem into a scoped engineering project - Sound API design judgment, including compatibility, pagination, error handling, and data contracts - Developer-facing data APIs, real-time delivery, or large historical datasets - ClickHouse or other analytical databases; Kafka or similar streaming systems - Blockchain indexers, EVM logs and traces, finality, or non-EVM data models - Storage migrations and performance or cost optimization under production traffic
