Work that impacts your future.

The largest language models in the world still fail at undergraduate-level mathematics. You're the feedback loop that fixes this — one proof at a time.

01-Rigor

A platform built for rigor

DataAnnotation is selective by design. We recruit mathematicians, researchers, and domain experts because the work demands it.

02-Signal

Direct impact on AI development

The problems you’ll evaluate are domain specific. You’ll review multi-step proofs, assess model-generated reasoning, and identify exactly where and why a mathematical argument breaks down. Your judgement shapes the future of AI within the mathematical field.

03-Flexibility

Work on your schedule

No fixed hours, no standups, no managers. Tasks are available 24/7 and you choose when and how much to work. Most contributors work 10–50+ hours per week around their primary commitments. You set the pace.

04-Rate

Premium compensation

Math expertise is scarce and we pay accordingly. Rates start at $50/hour and scale with complexity and performance. Contributors with strong quantitative backgrounds consistently rank among our top earners on the platform.

Three steps.
No overhead.

01

Apply & Qualify

Complete a math assessment. We evaluate your proof-writing, problem-solving, and ability to identify logical errors. No resume required.

~30 min assessment
02

Get Matched

Based on your assessment results, you're matched to projects in your areas of strength. Calculus, algebra, topology, number theory — you choose what fits.

Flexible scheduling
03

Work & Get Paid

Complete tasks on your own schedule. Each task has clear specifications and a defined scope. Payment is per-task, processed weekly, starting at $40/hour.

What you'll actually do.

Where models need you most.

These are the areas where current AI systems consistently struggle. Your expertise directly addresses the hardest open problems in mathematical reasoning.

Proof-Based Reasoning

Evaluate and construct formal proofs. Identify logical gaps, invalid inferences, and incomplete case analysis in model- generated arguments.

Real Analysis
Abstract Algebra
Topology

Multi-Step Problem Solving

Review complex solutions requiring sequential reasoning. Check that each step follows validly from the last and that no intermediate steps are skipped.

Calculus
Differential Equations
Combinatorics

Symbolic Logic & Formalization

Assess the model's ability to translate natural language into formal mathematical notation and reason within formal systems.

Mathematical Logic
Set Theory
Graph Theory

Edge Cases & Counterexamples

Identify where models fail on boundary conditions, degenerate cases, and subtle counterexamples that break general claims.

Analysis
Algebra
Number Theory

Quantitative Modeling

Evaluate applied mathematics problems involving optimization, statistical reasoning, and mathematical modeling of real-world systems.

People love the work.

A few threads from contributors who’ve been at it for a while.

What I love most about DA: it's an actual meritocracy

What I absolutely love about working at DA is the meritocracy. The higher the quality of your work, the higher the reward.

Creating complex coding scenarios, doing deep analysis of models, and synthesizing results are all part of my daily routine, and I love it.

u/textartguy

Belated Milestone Post

Been working since March 2024. I honestly feel so lucky to have both found this job and to have been able to keep it for so long.

I thought I might make a few grand max at the start.

u/Sharp-Sherbert-4194

100K!

Hit 100k the other day! I do this full time. Not what I originally intended when I signed up, but I've managed so far.

I started as a generalist but I have coding work too.

u/Emelody_cellobabe

DA has seriously changed my life

This work has opened up so many opportunities for me and is now enabling me to work full-time independently.

I started as a generalist, then passed the coding eval and have more often than not had plenty of work.

u/E13AN0R

Just hit 75k!!

Started almost a year ago and have just hit this milestone :) I had just graduated from uni when I started doing this and it was a lifesaver whilst I was looking for graduate jobs.

I'm based in the UK and I have a Master's degree in physics so I do a mix of specialist stem, coding, and sometimes generalist projects.

u/LeatherScience633

DA saved me, and I wish I could say thanks

In just 2 months I have already paid off my debt that would have taken me around an year to pay back. I can also leave my extra jobs and actually focus on my passion instead.

Working for them has been the best thing to happen to me so far.

u/CharacterBlood1495

Hit the 10k mark in one month : )

I have earned 10k in a month (my first month started at the end of April). I needed this and will definitely continue working with them.

I plan to keep working and be able to pay for a masters maybe in the fall.

u/OhLemons

Broke 130k this month!

I love that I can switch between coding tasks and those with rubrics, and that the work is always changing, so it never gets boring.

The taxes hurt, but it is worth it to help support the services like free healthcare here in Canada.

$40k - I Love You Data Annotation <3

Data Annotation has saved my ass financially and allowed me to help out my loved ones. Couldn't ask for a better job.

I've been working about 2-3 hours a day, 5 days a week, for just over 2 years.

u/PossibilityNo1696

200k Club

Treated DA as pretty much full time for the past 3 years and its been a god send for me.

I've saved a huge amount of money working from home, managed to work on a part time masters degree, and also been able to spend more time on myself.

u/Responsible-Fly-3808

My personal experience with DA [CODING]

In less than 2 months I've made a little over $20k, which honestly still feels surreal typing out.

A lot of it feels like real engineering/problem-solving work — debugging code, evaluating implementations, reasoning about edge cases.

u/MCSquareGlobe

Actually can help pay student debt now

This made living as a grad student actually affordable. In 2 weeks I just over doubled what I normally make.

Half of what I need to do in grad school is writing, so writing practice has been well needed.

u/physicsandwolves

100k club

Thanks DAT, I've been able to live an awesome life because of this job. Traveled to 28 countries, built a wrap around deck for my mom, created a massive garden, and so much more!

You can do it too, keep up the good work people!

u/neverenoughpepper

Jumping on the Milestone bandwagon

It's been a long, almost 3 year journey. Coder, self taught, and the first year or so was really, really tough. But I have no words for how thankful I am for DA.

I've had some amazing jobs in my life, but none compare to the constant challenges and rewards of this one.
