Machine Learning Engineer — AI Data Trainer About The Role What if your technical expertise could directly shape how the world's most advanced AI systems reason, plan, and solve problems? We're looking for Machine Learning Engineers to help train cutting-edge AI models by demonstrating how expert minds think through complex technical challenges — step by step. This isn't prompt engineering or basic annotation.

You'll be creating the gold-standard reasoning traces that teach AI models how to strategize, use tools effectively, and reach reliable conclusions in real-world environments. Your work will have a direct, measurable impact on the next generation of AI. This is a fully remote, flexible contract role designed for senior technical professionals who can commit anywhere from 10 to 40 hours per week.

Organization: Alignerr

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week What You'll Do Construct precise, structured reasoning logs that walk through sophisticated technical problems from start to finish

Document sequential decision-making and strategic planning workflows that reflect genuine expert thinking

Demonstrate proficient tool selection and use across complex, multi-step technical scenarios

Generate high-quality training datasets that show AI models what reliable, rigorous problem-solving looks like

Review and critically evaluate AI-generated reasoning steps — identifying gaps, errors, and opportunities for improvement





Work independently and asynchronously on task-based assignments at your own pace Who You Are Experienced professional with a robust background in Machine Learning, Software Engineering, or a related technical discipline

Exceptional at breaking down complex logical processes and articulating them clearly in writing A structured, methodical thinker who naturally documents their reasoning — not just their conclusions

Sharp critical eye — you can audit AI-generated reasoning and spot where it goes wrong

Self-directed and reliable when working independently without close supervision

Holds a Master's Degree or PhD in a relevant technical field Nice to Have Prior experience with data annotation, data quality evaluation, or AI/ML evaluation pipelines

Familiarity with LLM behavior, RLHF, or AI alignment concepts

Background in technical writing, research documentation, or systems design

Experience working with AI tools, APIs, or coding assistants in a professional context Why Join Us Work directly alongside leading AI research labs on projects shaping the frontier of AI

Fully remote and flexible — structure your work around your life, not the other way around

Freelance autonomy with the depth and substance of high-impact technical work

Gain rare, behind-the-scenes exposure to how state-of-the-art LLMs are trained and evaluated

Contribute to AI systems that will influence how technology reasons and solves problems at scale

Potential for ongoing work and contract extension as new projects launch
