Software Engineer (Open Source Contributor)

Pay: 50–100/hour

Role Type: Contractor

Location: Anywhere in the world, remote

Key Responsibilities

• Coding Task Development: Create realistic, technically challenging programming tasks involving bug fixes, feature development, code refactoring, and performance optimization.
• Reproducible Environment Setup: Build deterministic reinforcement learning environments with the necessary dependencies, test suites, configurations, and execution instructions.
• Reference Solution Implementation: Develop reliable golden reference solutions that demonstrate the expected behavior and satisfy all task requirements.
• Automated Verification: Design deterministic evaluators and test cases that accept valid implementations while rejecting incorrect, incomplete, or non-compliant solutions.
• Software Debugging: Investigate complex software defects, troubleshoot unexpected behavior, and resolve performance bottlenecks across diverse codebases.
• Feature Engineering: Implement robust and scalable features while following established software development principles and coding standards.
• Code Refactoring and Optimization: Improve existing codebases by enhancing readability, maintainability, execution efficiency, and long-term reliability.
• Code Review and Validation: Review code contributions and technical submissions for correctness, clarity, performance, and adherence to best practices.
• Technical Documentation: Document problem statements, implementation decisions, debugging strategies, testing procedures, and solution reasoning to support high-quality AI training and evaluation.
• Continuous Improvement: Refine tasks and evaluation criteria based on observed model behavior and identified weaknesses.

Required Qualifications

• Strong software engineering experience in one or more programming languages, including Python, Java, C++, Go, Rust, or TypeScript.
• Demonstrated experience developing backend systems, scalable services, APIs, or complex software applications.
• A clear track record of open-source contributions, preferably supported by a GitHub profile or equivalent public portfolio.
• Strong understanding of data structures, algorithms, software design principles, and debugging techniques.
• Practical experience with automated testing, code validation, and software quality assurance.
• Ability to identify and resolve complex bugs, implementation errors, and performance bottlenecks.
• Experience developing new features and improving existing codebases.
• Strong analytical thinking, problem-solving, documentation, and technical communication skills.
• Ability to work independently, follow detailed technical specifications, and deliver reproducible, verifiable solutions.
• Interest in AI systems and understanding how software engineering expertise can support AI model training and evaluation.

Opportunity Snapshot

• Time Commitment: Approximately 15 hours per task run, depending on complexity and individual workflow.
• Flexible Schedule: Work with flexibility while meeting task requirements and weekly submission minimums.
• Getting Started: Selected candidates receive onboarding instructions and the resources required to begin.
• Portfolio Requirement: A public GitHub profile or another portfolio demonstrating relevant open-source contributions is preferred.
• Alternative Assessment: Candidates whose public portfolios do not sufficiently demonstrate their skills may be required to complete a HackerRank technical assessment.
• Compensation: Payment is based on completed tasks that meet the specified quality and acceptance criteria.

Selection Process

1. Application: Submit your application and complete the initial screening questions.
2. AI Interview: Complete an approximately 20-minute interview focused on your technical experience and problem-solving approach.
3. Technical Assessment: Complete a HackerRank assessment if your portfolio does not adequately demonstrate the required expertise.
4. Hiring Manager Review: Your application, technical capabilities, and assessment results will be reviewed.
5. Onboarding: Selected candidates receive onboarding materials and instructions for beginning their assignments.

Candidates are expected to complete interviews and assessments independently so their technical judgment and problem-solving abilities can be evaluated accurately.

Expected Availability

The selection process may move quickly, with positions often filled within approximately 48 hours. Successful candidates should be prepared to begin their first tasks within 24–48 hours after completing onboarding.
