Machine Learning Engineer (AI Data Trainer)
About The Role
What if your expertise in machine learning could directly shape how the next generation of AI models reason, plan, and solve real-world problems? We're looking for Machine Learning Engineers to help train cutting-edge AI by demonstrating how expert technical minds actually think — step by step, tool by tool, decision by decision.
This is a fully remote, flexible contract role built for experienced ML and engineering professionals who want to put their deep technical knowledge to work at the frontier of AI development.
Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week
What You'll Do
Construct precise, well-structured reasoning logs that walk through sophisticated technical problems from start to finish
Document sequential decision-making workflows — how you strategize, select tools, and adapt your approach
Generate high-quality training data that shows AI models what expert-level problem-solving actually looks like
Audit and refine AI-generated reasoning chains to identify gaps, errors, or logical inconsistencies
Demonstrate proficient tool use across complex ML and engineering scenarios
Work independently and asynchronously — fully on your own schedule
Who You Are
Professional background in Machine Learning, Software Engineering, or a closely related technical discipline
Exceptional ability to articulate complex reasoning and methodologies in a clear, structured way
Strong critical thinking skills — you can evaluate a line of logic and spot exactly where it goes wrong
Comfortable working independently on intellectually demanding, task-based assignments
Master's Degree or PhD in a relevant technical field
Nice to Have
Prior experience with data annotation, data quality assurance, or AI evaluation workflows
Familiarity with large language models (LLMs) and how they're trained or fine-tuned
Background in technical writing, documentation, or instructional design
Experience working across multiple ML frameworks or toolchains
Why Join Us
Work directly with leading AI research labs on genuinely cutting-edge projects
Fully remote and flexible — work when and where it suits you
Freelance autonomy with the structure of meaningful, high-impact technical work
Rare inside access to how frontier LLMs are built and trained
Potential for ongoing work and contract extension as new projects launch
