• Work effectively with existing codebases and architectures.

Debugging & Performance

• Identify and resolve complex software bugs.
• Diagnose system bottlenecks and performance issues.
• Optimize software for performance, reliability, and maintainability.
• Refactor existing codebases to improve quality and efficiency.

Testing & Verification

• Develop deterministic verifiers that accept reasonable valid solutions and reject invalid implementations.
• Use automated testing to validate software behavior and correctness.
• Evaluate implementations against expected functionality and edge cases.
• Ensure coding tasks and verification logic are precise and reliable.

Code Review & Technical Evaluation

• Review software implementations for correctness, quality, and maintainability.
• Apply strong engineering judgment when assessing different approaches.
• Use algorithms, data structures, and foundational computer science principles to evaluate solutions.
• Provide clear technical reasoning and feedback.

Required Skills & Experience

• Strong software engineering experience with scalable services and APIs.

• Professional experience with one or more of:

• Python

• Java

• Rust

• TypeScript

• C++

• Go

• Node.js

• Strong debugging and problem-solving skills.

• Experience implementing software features and resolving complex bugs.

• Experience with performance optimization and automated testing.

• Strong code review instincts and software quality judgment.

• Solid understanding of algorithms, data structures, and foundational computer science concepts.

• Experience refactoring and improving established codebases.

• Ability to work with large or unfamiliar software projects.

• Strong analytical and technical communication skills.

• Ability to work independently and deliver high-quality technical outputs.
