Junior Software Engineer

to contribute to the evaluation and improvement of advanced artificial intelligence systems. This opportunity is ideal for early-career software engineers with strong programming fundamentals, analytical thinking, and practical experience developing and reviewing software applications.
In this role, you will evaluate AI-generated code for correctness, quality, efficiency, and design. You will create challenging programming problems, develop reference solutions and test cases, and assess AI models ability to solve real-world software engineering challenges. You will also review technical reasoning related to debugging, architecture, and system design, providing structured feedback to improve the reliability and performance of AI-generated solutions.
The ideal candidate has professional software engineering experience, a solid understanding of programming principles, and the ability to explain technical decisions clearly. Prior experience in artificial intelligence is not required.
Requirements
Key Responsibilities
AI-Generated Code Evaluation:

Review AI-generated code for functional correctness, readability, maintainability, efficiency, and adherence to software engineering best practices.
Coding Problem Development:

Design challenging programming problems that assess algorithmic thinking, debugging skills, implementation quality, and practical engineering judgment.
Reference Solution Creation:

Develop accurate, well-structured reference solutions that demonstrate effective approaches to solving software engineering problems.
Test Case Development:

Create comprehensive test cases to validate functionality, identify edge cases, and detect incomplete or incorrect implementations.
Technical Reasoning Assessment:

Evaluate AI-generated explanations and decisions involving software architecture, system design, debugging, and implementation strategies.
Code Quality Analysis:

Identify bugs, inefficient algorithms, poor design choices, security concerns, and violations of established coding standards.
Technical Feedback:

Provide detailed, actionable feedback explaining errors, weaknesses, and opportunities to improve code quality and model performance.
Documentation:

Clearly document problem requirements, expected behavior, solution approaches, testing procedures, and technical evaluation findings.
Quality Assurance:

Ensure that coding tasks, reference solutions, and evaluation criteria are accurate, consistent, and reproducible.
