Job Description: Java Developer for Hypertest SDK Development

[See assignment at the end as well]

Company Overview

At Hypertest (https://hypertest.co), we're not just writing code; we're rewriting the rules of software development.

Our autonomous testing tool has already transformed the NodeJs ecosystem for developers at more than 50 teams, and now we're bringing this revolution to Java with your help.

Our Mission: Save developers from the mundane. We automate test case generation, letting you bid farewell to countless hours spent on JUnit, Mockito, RestAssured, Postman, etc.

Imagine a development cycle where your focus is purely on creating, not correcting.

Role: Java Developer

HyperTest seeks a Senior Java Developer with profound expertise in Java's core mechanics and a passion for solving complex problems. This role is central to the development of our Java SDK, crucial for expanding HyperTest's functionalities. Ideal candidates will have a strong background in Java, including experience with library patching, bytecode manipulation, and observability frameworks like OpenTelemetry, New-Relic, Datadog etc.

Location

This is a hybrid position based in Gurugram.

Key Responsibilities

• Develop the HyperTest Java SDK, employing advanced Java techniques for runtime library manipulation and data mocking.
• Extend OpenTelemetry for observability and monitoring in distributed systems, ensuring our SDK integrates seamlessly with modern development ecosystems.
• Create solutions for simulated testing environments that operate in various modes without modifying the original application code.
• Serve as a Java subject matter expert, guiding the team in best practices and innovative software development approaches.

Qualifications

• Java Expertise: Extensive experience in Java, including familiarity with its internals, memory model, concurrency, and performance optimization. Not just experience with high-level frameworks, but a solid understanding of underlying principles and the ability to manipulate Java's core functionalities.
• Software Architecture: Strong grasp of software design patterns, architectural principles, and the ability to solve complex problems with efficient, scalable solutions.
• Analytical Skills: Exceptional problem-solving abilities, capable of addressing complex challenges and driving innovative solutions.
• Communication: Excellent verbal and written communication skills, essential for teamwork and collaboration.
• Specialized Knowledge: Experience with bytecode manipulation, library patching (e.g., Byte Buddy), and a clear understanding of Java's compilation and execution process.

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.
• 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.

Why Join HyperTest?

Joining HyperTest means being at the forefront of the automated testing revolution. We offer a dynamic work environment, opportunities for professional growth, and the chance to make a significant impact on our product and the wider development community.
