Kotlin Programmers - AI Training - Long-term Project

About OpenTrainOpenTrain is the #1 platform for finding and building careers in AI training and data labeling. Contributors on OpenTrain help shape how modern AI systems learn by producing, reviewing, and improving the examples models are trained on.

We connect skilled contributors with projects across the AI industry so you can build a profile, apply quickly, and grow your career doing remote, flexible work that directly impacts state-of-the-art systems.

About AI training workAI training (also called data labeling or human feedback work) is the human side of building intelligent systems: people create and check examples that teach models how to write, reason, and code.

This project focuses on training code-generation models using Kotlin examples and corrections. These roles are often remote and flexible, letting you contribute part-time while gaining hands-on experience with cutting-edge AI development workflows.

Role overviewWe are looking for skilled Kotlin developers to join a forward-thinking AI training project.

You will create Kotlin code snippets and short programs from prompts, review and debug AI-generated Kotlin, and produce accurate training data that helps models generate correct, idiomatic code. This is a long-term engagement (6+ months) with a weekly commitment of 20–40 hours.

You will work remotely as a contractor and set your own hours within those weekly expectations.

Position: Contractor, part-timeCommitment: 20–40 hours per week for 6+ monthsLocation: Remote — worldwideRate: $9.50 USD per hourWhat you'll doYour tasks combine hands-on Kotlin development with annotation work to build high-quality training examples the model can learn from.

Write short Kotlin programs and code snippets from text prompts.Review, debug, and refine Kotlin code produced by AI models.Document fixes and optimizations so examples are reproducible and clear.Label and organize examples to create structured training datasets and follow project-specific standards.RequirementsCandidates must meet the technical and logistical requirements below.

We will send a Kotlin coding assessment after you submit your proposal.

Bachelor’s or Master’s in Computer Science, Engineering, or related field.At least 2 years of professional software development experience with a strong focus on Kotlin.Proven ability to develop, troubleshoot, and optimize Kotlin code.Effective communication skills in English and ability to work in a remote team.Stable internet connection and reliable electricity to ensure consistent remote work.Availability to commit 20–40 hours per week for at least 6 months.Note: candidates with less than 2 years of Kotlin experience will receive a lower proposal qualification score.Who should applyThis role suits Kotlin developers who want part-time, meaningful work that directly improves AI code generation.

If you enjoy writing clear, idiomatic Kotlin and explaining fixes, you'll make strong training examples for models. Entry-level applicants are considered, but the project expects at least two years of Kotlin experience for full qualification.

Compensation, tools, and logisticsThis is a contractor role paid hourly at $9.50 USD per hour. You will use the project's annotation tools (listed as Other) and follow project guidelines for formatting and submission.

You will receive a coding assessment after you apply; successful completion is required to join the project.

Employment types: Contractor, Part-timePayment: PAY_PER_HOUR at $9.50 USD/hourLabeling software: Other (project-specific tools will be provided)How to applySubmit your proposal describing your Kotlin experience and availability.

After you apply, we will send a Kotlin coding assessment to evaluate skills and fit. Be sure to include details about recent Kotlin projects, your typical weekly availability within the 20–40 hour range, and confirmation you meet the degree and remote-work requirements.
