Mathematician (Foundations / Formalization)
- Location: Remote
About the job
At Alignerr, we partner with the world’s leading AI research teams and labs to build and train cutting-edge AI models. We’re seeking mathematicians who enjoy working with formal systems, rigorous proof methods, and the foundational structure of mathematical reasoning, particularly within Lean. This role supports frontier AI research by formalizing and auditing advanced mathematics and logical structures using modern proof assistants. Organization: Alignerr Position: Mathematician (Foundations / Formalization) Type: Hourly Contract Compensation: $170–$200 /hour Location: Remote Commitment: 10–40 hours/week
What You’ll Do:
Your work will sit at the intersection of pure mathematics, logic, and formal systems engineering.
- Formalize advanced mathematical arguments within Lean 4 (think theorems from Textbooks across various disciplines)
- Contribute to the continual advancement of large-scale formal mathematical libraries (e.g., mathlib) through clean, readable proof construction.
What We’re Looking For:
Preferred:
- Master’s degree or PhD in Mathematics or a closely related field
- Strong background in rigorous proof writing and reasoning
- Experience with formal proof assistants. Lean 4 strongly preferred. * Ability to turn informal mathematical ideas into structured formal proofs

Frequently Asked Questions
What is the assessment actually like?
Notoriously strict. Alignerr uses TestGorilla for role-specific timed tests — a blank coding environment for engineers, rigorous grammar and fact-checking for writers. There is almost no hand-holding. The critical catch: this is essentially a one-shot process. Fail or abandon the assessment, and you are typically locked out of that role permanently with no option to retake.
How quickly can I start earning after I pass?
Not immediately. Even after passing the assessment and completing identity verification (via Persona) and billing setup (via Deel), you may sit in a waiting pool for weeks or months. You only start earning when a project matching your specific skills launches and you are officially assigned. Do not plan around Alignerr income until you are actively on a project.
Is there a community?
Yes — and it is one of Alignerr's genuine strengths. Once assigned to a project, you are added to Slack channels where you can ask questions, get rubric clarifications from admins, and talk to other AI trainers. This is rare in AI training and makes a real difference when guidelines are ambiguous or change mid-project.
Is this traditional consulting?
Not exactly. You act as a "Teacher" for advanced AI. Instead of client deliverables, you are given complex scenarios to evaluate. You grade the AI's logic, correct its hallucinations, and provide expert-level reasoning. Your job is to train the model to think like you do.
Why is the pay so high?
This role requires deep, verified expertise. General knowledge isn't enough; the model is specifically being trained on "edge cases"—the rare, difficult, or highly technical nuances that only a senior professional would know.
What is the workload like?
This is cognitive, deep work. Unlike simple data labeling, you might spend 45-60 minutes on a single task, researching citations or verifying complex calculations. Quality is prioritized over speed.
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.
