Data Scientist (Masters)

Data Scientist (Masters) — AI Data Trainer

Master's or PhD required | Remote contract role


About the Role

What if your deep knowledge of machine learning, statistical inference, and data engineering could directly shape how the world’s most advanced AI thinks and reasons?

We’re looking for data scientists with advanced training to help build and stress-test cutting-edge AI models. You’ll design complex, expert-level challenges that push AI systems to their limits—and when they fail, you’ll document exactly why, so we can make them better.

This is a fully remote, flexible contract role. No prior AI industry experience required—just domain expertise and a sharp analytical mind.


Organization & Details

  • Organization: Alignerr
  • Type: Hourly contract
  • Location: Remote
  • Commitment: 10–40 hours/week

What You’ll Do

  • Design Advanced Challenges
    • Create expert-level data science problems covering:
      • Hyperparameter optimization
      • Bayesian inference
      • Cross-validation strategies
      • Dimensionality reduction
      • And beyond

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
