• Introduce, document, review, and successfully pass the review of technical designs, such as public APIs, new core features, and new services among others.
• Implement agreed-upon functionality.
• Participate in the peer review process.
• Investigate complicated incidents.
• Participate in laying out efficient infrastructure for code to run.
• Measure and improve performance.

Required Skills And Qualifications

• Knowledge of at least one of the following languages: Java, C++, C#, or Go, including all low-level technical details.
• Experience with REST APIs and server-client communication, including WebSocket and Server-Sent Events (SSE).
• Experience with multi-threaded development and synchronization patterns.
• Redis or practical experience with comparable multi-master storage technology.
• Spark, Flink, Ray, or practical experience with a comparable distributed computation engine.
• Vert.x, Netty, or practical experience with a comparable high-performance communication library.
• Background in Computer Science.
