Job description

We are sharing a specialised consulting opportunity for experienced Software Engineers with strong backend expertise, scalable service development, debugging, automated testing, feature implementation, and codebase optimisation to contribute to advanced AI training and software-engineering evaluation projects.

Selected professionals will create realistic and technically challenging coding tasks, develop reference implementations and deterministic verifiers, and apply practical software-engineering judgement to feature development, bug fixing, refactoring, performance optimisation, and testing. No prior AI experience is required.

Key Responsibilities

Coding Task Development

  • 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

Backend Engineering & Feature Implementation

  • 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

Debugging, Refactoring & 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

Deterministic Verification & Testing

  • 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

Technical Evaluation & Quality Review

  • 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

Ideal Profile

  • 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
  • Experience designing test strategies or maintaining large test suites is particularly valuable
  • Ability to diagnose flaky tests and improve testing standards
  • Strong analytical and problem-solving skills
  • Clear technical written communication
  • Ability to work independently in a flexible remote environment
  • No prior AI-training or model-evaluation experience is required

Engagement Details

  • Independent contractor engagement
  • Fully remote
  • Expected commitment: approximately 15 hours per week
  • Flexible schedule across weekdays or weekends
  • Displayed compensation range: $30–$100/hour
  • Actual compensation structure is output-based, with payment made per task that meets project specifications
  • Time required per task may vary depending on experience and workflow
  • Minimum weekly submission requirements apply; the source does not specify the exact number of required tasks
  • Selection may include an approximately 30-minute AI interview, a tentative technical assessment, and hiring-manager review
  • Interview, assessment, and project work must be completed without outside assistance
  • Roles are typically filled within approximately 48 hours
  • Selected contributors should be prepared to begin initial tasks within approximately 24–48 hours after onboarding
  • Work will involve coding-task development, feature implementation, debugging, refactoring, deterministic verification, and technical evaluation
  • Work must be completed without using confidential or proprietary information belonging to any employer, client, institution, organisation, or other third party
