About this Role

From the Mercor listing

Computational Bayesian Statistics and Applied Mathematics Expert

About the Project

We're building a large-scale benchmark to test how well advanced AI systems can solve hard scientific and engineering problems. As a task designer, you'll create challenging computational problems that check whether AI can use real scientific software to do research-level work — running simulations, interpreting results, designing experiments, and uncovering hidden information from data.

This isn't a typical data-labeling job. You'll design original, graduate-level problems based on real scientific workflows, test them against cutting-edge AI models, and fine-tune them until the difficulty is just right.

What You'll Do

You'll create problems that require skilled use of specialized scientific software. Some will ask the AI to compute exact answers from a fully defined setup — testing whether it can correctly carry out complex, multi-step workflows. Others will be harder: the AI must plan a series of queries or experiments to uncover information that isn't directly visible, which means thinking strategically about what to measure, how to read partial results, and how to narrow down the possibilities efficiently.

Each problem goes through a testing loop against state-of-the-art AI models, and you'll refine it until it hits the target difficulty.

Domains & Tools We're Hiring For

We're especially interested in experts with deep, hands-on experience in:

Computational Bayesian Statistics and Applied Mathematics — working with libraries such as:

  • Bayesian statistics: PyMC, PyStan, PyJAGS, CmdStanPy

  • Applied mathematics and numerical PDEs: FEniCS, FEniCSx, DOLFINx, scikit-fem, FiPy, Devito, Dedalus

  • Computational topology: GUDHI

  • Differential algebra: DACEyPy

  • Optimization: lmfit

Experience with MCMC, Bayesian modeling, finite element or finite difference methods, mesh-based numerical modeling, computational topology, differential algebra, or other specialized Python-based math and statistics methods is valuable. You don't need experience with all of these — solid experience with even one will be highly regarded.

Experience with other specialized software in this domain will also be considered.

What Makes a Strong Candidate

You have graduate-level expertise (MS or PhD preferred) in the domain above, with real hands-on experience using these tools — not just theoretical knowledge. You've written code using these libraries to solve actual research problems, and you understand where they break, what their edge cases are, and what makes a problem genuinely hard rather than just complicated.

Beyond domain expertise, the best candidates think like puzzle designers: building problems where the challenge comes from smart reasoning rather than raw computation, where several approaches seem plausible but only careful analysis reveals the right one, and where surface-level pattern matching won't get you to the answer.

Requirements

  • Graduate-level training in a relevant STEM field (MS, PhD, or equivalent research experience)

  • Proven proficiency with at least one of the listed scientific software libraries, shown through research publications, open-source contributions, or professional work

  • Strong Python skills — you'll be writing problem setups, oracle functions, and solution validators

  • Ability to work independently and refine problem designs based on feedback

  • Comfortable working in a Linux/terminal environment with remote compute sandboxes

  • Available for at least 15–20 hours per week

Nice to Have

  • Experience across multiple listed domains or tools

  • Familiarity with benchmark or evaluation design

  • Background in scientific teaching or exam/problem-set design

  • Experience with computational reproducibility and containerized environments

Please note: This application includes a coding assessment as part of the evaluation process.

Requirements

  • Must be eligible to work in Remote
  • Fluent proficiency in English (Written & Verbal)
  • Reliable high-speed internet connection
  • Bachelor's degree or equivalent professional experience
  • Demonstrated expertise in Mathematics

Why This Role

Rare opportunity for top 1% experts. Earn $85/hr contributing to the world's most advanced AI labs. This is one of the few roles where academic precision is valued as highly as commercial output.

Frequently Asked Questions

Is Mercor for freelancers or full-time contractors?

Mercor places you with one client for a defined engagement, like 'Python Tutor for 3 months', rather than having you grab small tasks from a shared queue. Most roles function as steady contract work, not one-off gigs.

Does Mercor's application require an on-camera interview?

Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.

Does it cost money to apply to Mercor?

No, applying and joining Mercor is free. Mercor's revenue comes from a fee it charges the client on top of your hourly rate, not from applicants. Treat any request for payment to join as a red flag.

What does task-based AI training work actually look like?

Practical, hands-on data work: recording short videos, categorizing images, rating text responses, or analyzing data. Tasks are designed to be short and distinct, typically 5 to 60 minutes each.

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.

What does Mathematics work look like for a Computational Bayesian Statistics and Applied Mathematics Expert?

Tasks here are scoped to Mathematics, not generic labeling. As a Computational Bayesian Statistics and Applied Mathematics Expert, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Mathematics) rather than following a one-size-fits-all rubric. If you don't have hands-on Mathematics background, this is likely not the right listing to start with.

How many hours per week does this role require?

Based on the listing, this role is scoped at 15–20 hours per week. Treat this as a real commitment expectation, not a loose estimate.

What happens when I click Apply on this listing?

You'll be taken to Mercor'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.

How soon will I start working after applying to Mercor?

Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
