Role Overview

As a Principal Python Engineer - ML Infrastructure, you will solve complex coding challenges to create "Golden Data" for training advanced code-generation models. You will likely engage in "red-teaming" (adversarial testing) to find logic gaps in AI code, write unit tests for generated snippets, and provide expert-level refactoring. This is pure technical work—no meetings, just deep-dive problem solving in languages like Python and C++.

Requirements

  • Native or fluent English speaker
  • Full-stack developer experience with a strong systems programming background
  • 5+ years of professional experience writing production Python, specifically for large-scale infrastructure or platform engineering.
  • Expertise in designing distributed computing systems and managing concurrency with advanced asynchronous patterns.
  • Deep understanding of Python internals (GIL limitations, memory profiling) and experience optimizing performance for compute-heavy workloads.
  • Clear written and verbal communication skills for driving technical strategy and architectural decisions.

Compensation Analysis

Join the workforce powering the AI revolution. With a competitive rate of $62.5/hr and remote flexibility, this role allows you to balance professional growth with personal freedom. No previous AI experience is usually required—just your domain expertise.

Frequently Asked Questions

How do I get started?

Review the hiring process above and follow the steps outlined. Each platform has different requirements, so make sure you meet the eligibility criteria before applying.

Is this work legitimate?

Yes. All platforms listed on aitrainer.work are legitimate and pay reliably. However, always verify payment methods and read reviews before committing significant time.

Is this just labeling data?

No. This is closer to academic research. You will likely be writing or verifying complex proofs, solving advanced equations, or checking the logic of a model's step-by-step reasoning. The goal is to teach AI systems to reason deeply in your field.

Do I need a PhD?

For the highest pay tiers in this category, a PhD (or current enrollment) is usually expected. However, the most important factor is your ability to pass the domain assessment. If you can solve the problems, the degree is secondary.

Is the work continuous?

Work in niche fields is often project-based. A specific "campaign" (e.g., training a model on Quantum Mechanics) might last for a few weeks. It is best to treat this as a high-paying fellowship or grant rather than a permanent daily job.

What is the barrier to entry?

Alignerr is known for difficult technical assessments. You must pass a timed test in your specific domain (e.g., Python, Physics, or Language) before you are eligible for any paid projects.
