From the Handshake listing
Overview
Handshake is seeking Machine Learning PhDs to support AI research through flexible, hourly contract work. This is not a traditional academic or full-time role. You’ll apply your machine learning expertise to evaluate AI-generated content and provide feedback that helps AI systems better understand model architectures, optimization theory, statistical learning, and technical problem-solving.
This is an ongoing, project-based opportunity that can be done alongside research, teaching, postdoctoral work, or industry employment.
Details
This project involves using your experience in machine learning to design rigorous, domain-relevant questions and review AI-generated responses for accuracy, logical consistency, and technical soundness across ML concepts such as optimization, generalization, and model behavior. No prior AI evaluation or technical experience is required.
Fully remote with a flexible, asynchronous schedule and no minimum hour requirement; most contributors work approximately 5–20 hours per week when participating in an active project.
Placement depends on current project needs, with opportunities to be considered for future projects as they become available.
Qualifications
Doctoral students and graduates (including those currently enrolled in a PhD program or in postdoctoral positions) in Machine Learning or closely related fields such as Statistics, Computer Science, or AI.
Strong background in machine learning theory, algorithmic analysis, and applied mathematics, including familiarity with optimization, probabilistic modeling, and statistical inference.
Work authorization information
F-1 students who are eligible for CPT or OPT may be eligible for projects on Handshake AI. Work with your Designated School Official to determine your eligibility. If your school requires a CPT course, Handshake AI may not meet your school’s requirements. STEM OPT is not supported. See our Help Center article for more information on what types of work authorizations are supported on Handshake AI.

Why this role
$75/hr for Machine Learning Expert work puts your Data Science expertise on the same footing as an AI lab's own research staff, without the overhead of running a consulting practice around it.

Common questions
Can I use Handshake if I graduated years ago?
Probably not a good fit. Handshake's AI Fellowship roles target current university students and early talent within about 1-2 years of graduation. Experienced professionals typically find faster approval and better rates on Outlier or Mercor.
Is Handshake itself the employer for AI training roles?
For the AI Fellowship roles specifically, yes, Handshake acts as the employer of record. That's different from the rest of the site, which functions as a job board listing openings for other companies.
What does asynchronous AI training work mean in practice?
No set hours, no check-ins, no meetings. You log in when you want, pick up an available task, complete it, and submit; nobody is waiting on you in real time. That's different from remote employment, where you're expected online during business hours. The tradeoff: you're competing with others for available tasks, so an empty queue means there's simply nothing to do until more work is released.
Do task-based AI training roles require an interview?
Most skip a live interview entirely and gate access through an automated assessment or qualification task instead. Where we've confirmed the specific requirement for this listing, it's called out above in What We Know About This Role.
What does Data Science work look like for a Machine Learning Expert?
Tasks here are scoped to Data Science, not generic labeling. As a Machine Learning Expert, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Data Science) rather than following a one-size-fits-all rubric. If you don't have hands-on Data Science background, this is likely not the right listing to start with.
What specific skills does this listing call for?
Expert is named directly in the listing. If you don't have hands-on experience with this, expect the screening process to test for it directly rather than accepting adjacent experience as a substitute.
How much does this specific role pay?
This listing is posted at $75/hr, an hourly rate. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.
What happens when I click Apply on this listing?
You'll be taken to Handshake's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.
Is a PhD required?
For this specific role, yes, or near-equivalent professional depth. The credential gate is enforced at the assessment stage, not just on paper. That said, active PhD candidates and people with equivalent published research have qualified without a formal degree. The assessment is the real filter.
Are Handshake AI training listings internships?
Some are, some aren't. Handshake lists both standard internships and separate "AI Trainer" fellowships. Check the job description for "1099" or "Contract" language: that signals a freelance role, not W-2 employment.
