Requirements
- Core Java Mastery: Expert-level Java (8+) with a focus on Multithreading, Concurrency, and Asynchronous processing.
- Reactive Systems: Hands-on experience with Functional Reactive Programming (RxJava, Java 9 Flow API, or similar).
- Low Latency Messaging: Deep understanding of 60East AMPS, Kafka, or Solace. You should be comfortable with Pub/Sub, Point-to-Point, and durable subscriptions.
- Middleware & Networking: Expertise in socket programming and optimizing low-latency network communication.
- Modern Stack: Spring IoC/MVC, SQL (Sybase/PostgreSQL), and a solid grasp of Linux internals., You are a developer who possesses "mechanical sympathy"-you don't just write code; you understand how it impacts the hardware and the network. You thrive in environments where performance bottlenecks are identified and destroyed, and you enjoy the autonomy of owning a functional backlog within a global team.
