What is the difference between Remote Alignerr vs Remote Data Analyst?
| Aspect | Remote Alignerr | Remote Data Analyst |
|---|---|---|
| Required Credentials | Certification in alignment tools, basic data analysis skills | Degree in Data Science, Statistics, or related field; proficiency in data analysis software |
| Work Environment | Primarily remote, collaborative with project teams | Remote or hybrid, often working with data teams and stakeholders |
| Industry Usage | Used mainly in manufacturing, logistics, and quality control | Common across finance, marketing, healthcare, and tech sectors |
Remote Alignerr roles focus on aligning processes and systems, often requiring specific certification and industry-specific knowledge. Remote Data Analysts analyze data to inform business decisions, requiring strong analytical skills and relevant degrees. While both roles can be remote, their industry applications and skill sets differ significantly.

About the Role
What if your deep knowledge of formal mathematics could directly shape how the most advanced AI systems in the world reason, prove, and think? We're looking for mathematicians with a passion for rigorous proof and formal systems to help build the mathematical foundations that frontier AI depends on.
This is a fully remote, flexible contract role working at the intersection of pure mathematics, logic, and cutting-edge AI research. Brazil has a vibrant and growing mathematical community - if you live and breathe formal proof and know your way around Lean 4, this is a rare opportunity to contribute to frontier AI from anywhere in Brazil.
- Organization
: Alignerr - Type
: Hourly Contract - Location
: Remote - Commitment
: 10-40 hours/week
What You'll Do
- Formalize advanced mathematical arguments and theorems in Lean 4, spanning a wide range of mathematical disciplines
- Contribute to the growth and quality of large-scale formal mathematical libraries, including mathlib
- Construct clean, readable, and well-structured formal proofs that translate informal mathematical reasoning into rigorous machine-checkable form
- Audit and verify existing formal proofs for correctness, completeness, and logical integrity
- Work at the frontier of AI research, helping train the next generation of mathematically capable language models
Who You Are
- Hold a Master's degree or PhD in Mathematics or a closely related field
- Possess a strong background in rigorous mathematical proof writing and logical reasoning
- Have hands-on experience with formal proof assistants -
Lean 4 strongly preferred - Can fluently translate informal mathematical ideas into structured, machine-verifiable formal proofs
- Self-motivated and comfortable working independently in a remote, asynchronous environment
Nice to Have
- Prior experience with proof verification, theorem proving, or mathematical formalization projects
- Familiarity with mathlib or other large-scale formal mathematical libraries
- Background in data annotation, data quality evaluation, or AI training workflows
- Experience across multiple mathematical domains - topology, algebra, analysis, logic, and beyond
Why Join Us
- Work on frontier AI research alongside the world's leading AI labs and research teams
- Fully remote and flexible - structure your work around your life, not the other way around
- Freelance autonomy with the intellectual depth of meaningful, high-stakes technical work
- Contribute directly to formal mathematical libraries that will outlast any single project
- Gain rare exposure to how cutting-edge large language models are built and trained
- Potential for ongoing work and contract extension as new projects launch
