About the Job

Title: Software Engineer (Remote)

Engagement: Hourly contract (independent contractor)

Rate: USD 45-80/hour

Location: Remote – candidates based in the United States, United Kingdom, Canada, Europe, Singapore, Dubai, or Australia who are legally able to work as independent contractors in their jurisdiction.

Role Overview: One of our clients, a leading AI research organization, is developing advanced conversational AI systems that assist users with real-world software engineering and coding tasks. This role focuses on evaluating and improving how large language models (LLMs) reason about code, generate solutions, and explain technical concepts across a wide range of programming and system design scenarios.

Key Responsibilities:

  • Evaluate AI-generated responses to software engineering and coding queries for correctness, clarity, and completeness
  • Execute and test code to validate functionality, performance, and edge-case handling
  • Perform fact-checking using authoritative technical references and public sources
  • Annotate model outputs by identifying strengths, weaknesses, bugs, and conceptual gaps
  • Assess code quality, readability, algorithmic soundness, and explanation quality
  • Ensure outputs align with established conversational and technical guidelines
  • Apply standardized evaluation rubrics and benchmarks consistently

Required Qualifications:

  • Bachelor’s, Master’s, or PhD in Computer Science or a closely related field
  • Significant professional experience in software engineering or system design
  • Expert-level proficiency in at least one major programming language (e.g., Python, Java, C++, JavaScript, Go, Rust)
  • Ability to independently solve medium-to-hard algorithmic problems
  • Experience contributing to open-source projects with accepted pull requests
  • Strong familiarity with using LLMs for coding and understanding their limitations
  • Exceptional attention to detail and ability to detect subtle technical errors

Preferred Qualifications:

  • Prior experience with RLHF, model evaluation, or technical data annotation
  • Background in competitive programming or algorithmic problem solving
  • Experience reviewing or maintaining production-level code
  • Familiarity with multiple programming paradigms and technology stacks
  • Ability to explain complex technical topics to non-technical audiences

What Success Looks Like:

  • You consistently identify logical errors, inefficiencies, and misleading explanations in AI-generated code
  • Your feedback measurably improves the accuracy, reliability, and clarity of model outputs
  • You deliver high-quality, reproducible evaluation artifacts that strengthen AI system performance

Contract & Payment Terms:

  • Independent contractor engagement
  • Fully remote with flexible scheduling
  • Weekly payments via Stripe or Wise
  • Project scope and duration may vary based on performance and client needs
  • No access to confidential or proprietary employer data is required
  • H1-B and STEM OPT sponsorship is not available

Application Process:

  • Submit your resume for review
  • Selected candidates will complete a short technical and evaluation assessment
