Remote | Software Engineer — $30–$100/hour

24-MAG LLC connects experienced professionals with remote consulting opportunities across technical, evaluation, and project-based workstreams. The Software Engineer will contribute to AI training and software-engineering evaluation projects by creating coding tasks, developing backend services and deterministic verifiers, implementing features, debugging, refactoring, optimizing performance, testing, and reviewing technical quality.

Responsibilities:

• Create realistic software-engineering tasks involving feature implementation and bug fixes
• Design challenges that reflect professional backend-development scenarios
• Define clear technical requirements, constraints, and expected behaviour
• Ensure tasks are sufficiently complex to evaluate engineering reasoning
• Apply practical software-development experience throughout task creation
• Work across Java, Node.js, Go, Rust, TypeScript, Python, C++, or comparable technologies
• Develop and evaluate scalable backend services and APIs
• Implement complex features within established codebases
• Apply sound algorithms, data structures, and computer-science fundamentals
• Maintain strong standards for correctness, maintainability, and performance
• Identify and resolve software defects and system bottlenecks
• Diagnose unexpected behaviour across complex applications
• Refactor existing code to improve structure and maintainability
• Optimise implementation performance where required
• Evaluate trade-offs between reliability, complexity, scalability, and efficiency
• Develop deterministic verifiers for coding tasks
• Ensure verifiers accept reasonable valid solutions and reject incorrect implementations
• Design automated tests covering expected behaviour and edge cases
• Diagnose flaky or unreliable test behaviour
• Apply strong testing strategy and code-review judgement across assignments
• Review software-engineering outputs for technical accuracy and completeness
• Assess implementation quality against task specifications
• Identify weak reasoning, incomplete fixes, or inappropriate engineering approaches
• Provide precise technical feedback on submitted solutions
• Maintain consistent quality standards across repeated evaluation workflows

Requirements:

• Strong professional backend software-engineering experience
• Expertise in one or more of Java, Node.js, Go, Rust, TypeScript, Python, C++, or similar languages
• Track record of building scalable services and APIs
• Strong debugging and software-troubleshooting capabilities
• Experience identifying and resolving performance bottlenecks
• Proven ability to implement complex features in established applications
• Experience refactoring large or evolving codebases
• Strong understanding of algorithms and data structures
• Solid automated-testing and code-review instincts
• Ability to diagnose flaky tests and improve testing standards
• Strong analytical and problem-solving skills
• Clear technical written communication
• Experience designing test strategies or maintaining large test suites is particularly valuable
