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.
- Innovative Problem-Solving: Tackling complex Java-related challenges that reflect the technical depth required for this role.
This assessment will help us identify candidates who not only have the technical expertise but also the creativity and problem-solving skills essential for success at HyperTest.
