Ideal Candidate Profile

• Not Just Another Java Developer: We're looking for someone who has moved beyond just building applications with Spring Boot or similar frameworks. You should have an experience that demonstrates a deep understanding of Java, including direct manipulation of bytecode, custom library creation, and performance optimization.
• A True Java Enthusiast: You find excitement in exploring Java beyond the surface level, delving into its internals, and leveraging this knowledge to build innovative solutions.

Technical Assessment Overview

Shortlisted candidates will complete a short technical assessment focused on:

• Library Patching and Dynamic Data Mocking: Demonstrating advanced Java skills in runtime library functionality manipulation.
• OpenTelemetry Integration: Applying observability frameworks to trace and monitor distributed systems, a key component of our SDK development.
• Simulated Testing Environments: Creating flexible testing scenarios that replicate real-world conditions without altering the original code.
