We're excited about building a platform that supports a brand new economy based on true digital ownership and are proud to be recognized by Y Combinator, Forbes and BuiltIn as a top-ranked company/employer!

We are looking for the core architect and lead engineer on OpenSea v2.0 — making key recommendations and decisions on technology choices, event driven patterns, service topology, and overall design philosophy.

Responsibilities

• Form, communicate, and execute on a technical vision for the next generation of OpenSea’s architecture that leverages highly scalable and event-driven patterns
• Write reliable, low latency marketplace infrastructure software that will eventually process billions of dollars a day worth of transaction volume, including highly performant blockchain indexing systems, order management systems at scale, and REST & Websocket API endpoints
• Raise the bar for internal understanding of best practices in building highly performant & event-driven systems with “live” characteristics 
• Mentor and train other team members and act as an internal thought leader and agitator for architectural rigor and cleanliness

Desired Experience

• At least 6 years of experience as a software engineer, 1+ of which should have been in a low-latency retail crypto exchange
• Strong fluency in event-driven system design patterns, leveraging technologies such as Kafka, Flink, and Debezium, as well as distributed systems more generally
• Strong fluency in at least one of the following languages: Kotlin/Java, Typescript, Go 
• Strong fluency and opinionation in database choice and schema design for highly performant and scalable applications
• Familiarity with common architectural patterns in financial exchanges, including sequencer architectures, matching engines, and order books
• Blockchain or smart contract experience
