Psychiatrist

## About the work

We are building a dataset of real retail trading behavior: complete brokerage trade histories, paired with the trader's own explanation of how they trade and why they made their biggest decisions. The data is used to study and model how individual traders make decisions.

This is a one-time task, paid a flat **$400** on completion.

## What you will do

1. **Upload your trade history.** Export your complete transaction history from your U.S. brokerage account using the broker's standard export, and upload it to our platform. It must cover at least 24 months and include every trade, with none removed. Remove your name, account numbers, address and other personal details before uploading.
    
2. **Describe your trading style.** Write a short summary (about 100 to 250 words) of your strategy, typical holding period, the instruments you trade and the platforms you use.
    
3. **Explain your 5 biggest trades.** Pick at least 5 of your most significant or influential trades, such as large gains, large losses or high-conviction calls, with stocks preferred. For each, explain your reasoning at entry or exit and what information drove the decision. Keep any reflection on how it turned out separate from your original reasoning. Each explanation must name a specific trade in your history, with the symbol, date, side and quantity matching that trade.
    

The writing takes up to about 1.5 hours.

## Pay

- **$400, paid once** you have uploaded your full history and fully annotated at least 5 trades.
    
- Partial submissions are not paid: the upload and all 5 annotations are required.
    

## Who we are looking for

- **Location:** United States only.
    
- **Trading experience:** at least 2 years of active trading on your own account, and at least 1,000 trades over that period (about 2 per trading day).
    
- **Instruments:** stocks; options count too.
    
- **Broker:** your account is with a U.S. retail broker, such as Robinhood, Schwab, Fidelity, E\*TRADE, Webull or Interactive Brokers.
    
- **Background:** any. No minimum education and any field of study, from current college students to graduate-degree holders. Non-finance professionals, finance professionals and full-time traders all qualify. Current or former professional traders can take part using their own personal account only.
    
- **Age:** 18 or older.
    
- **Willing to** share your complete brokerage trade history, with no trades removed.
    

## Not a fit

- Fewer than 2 years of history, or fewer than 1,000 trades
    
- Trading only through an account you don't own, such as a managed, employer or prop-firm account
    
- Trading mostly crypto or futures
    

## Data license agreement

Taking part requires signing Mercor's Expert Content License Agreement, which covers how your trading history and annotations are licensed and used. You sign it as part of applying.

Cinematographer

# **About the Role**

We're hiring Writers on a contract basis for Project Sisyphus, a PII anonymization program. You work through business documents and structured records (CRM exports, email, tickets, chat logs, accounting data), deciding what is and isn't personal information, catching anything that was missed, and grouping related entities so the same person or organization is handled consistently. Reviewers check your work before it ships.

**We are working to build a lasting team.** This is an internal project that will run long into the future, and we want writers we can build lasting teams and structures around. Strong writers are the pool we promote reviewers from.

# What You'll Do

- Confirm, reject, add and correctly type PII across tasks that contain dozens to hundreds of individual decisions
    
- Group related entities (people, organizations, contact details) into the right clusters
    
- Find personal information that automated detection missed, and avoid tagging things that aren't personal
    
- Apply guidelines that are updated several times a week, using the version in force on the day you work
    
- Act on reviewer feedback quickly, and apply it across your other tasks rather than fixing one instance
    
- Work asynchronously with a distributed team, and raise ambiguous cases in the project channel rather than guessing
    

# What We're Looking For

Private Detectives and Investigators

**Help a leading AI lab ensure its models respond to people with care, balance and sound judgment.**

# 1\. Overview

A leading AI lab is seeking behavioral health experts to help evaluate and improve how its AI models handle sensitive, everyday conversations. People increasingly turn to AI for support with relationships, family dynamics, emotional wellbeing, personal beliefs and difficult life decisions. These conversations rarely involve crisis content, but they are exactly where a model's judgment matters most: whether it stays balanced, avoids taking sides, resists telling people what they want to hear, respects a person's beliefs without endorsing or dismissing them, and understands the limits of its role. You'll review these interactions, assess whether the model's responses are appropriate, neutral and safe, and help the lab's researchers define what good looks like. If you bring professional experience in mental health, counseling, social work or behavioral science, and you can articulate clearly why one response serves a person better than another, this role is for you. This is a part-time commitment of at least 20 hours per week, with the option to increase to up to 40 hours per week.

This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce.

# 2\. Key Responsibilities

- Evaluate conversations between users and AI models across topics such as relationship and family advice, emotional wellbeing, spiritual and metaphysical questions, and unconventional or unfounded beliefs, and assess whether responses are neutral, appropriate and safe.

- Identify patterns of concern, including excessive agreement, taking sides, reinforcing distorted or unfounded beliefs, moralizing, or overstepping into clinical or directive advice, and document them with clear written rationale.

- Develop rubrics, guidelines and reference responses that define a balanced, supportive and appropriately bounded reply, grounded in established practice from counseling and behavioral health.

- Design test scenarios and conversations that probe how models handle sensitive but non crisis topics.

- Collaborate with the lab's researchers and fellow experts to keep evaluation standards consistent, calibrated and well documented.

# 3\. Core Qualifications

- A degree in psychology, counseling, social work, behavioral health, behavioral science, human services or a closely related field, or equivalent professional experience in the mental health field.

- 3+ years of professional experience supporting people in a mental health, counseling or social services setting, for example as a therapist, counselor, clinical social worker, psychologist, psychiatric nurse, case manager, crisis counselor, peer support specialist or mental health advocate. Clinical licensure (for example LMFT, LCSW, LPC, LMHC, PsyD or PhD) is valued but not required.

- Demonstrated ability to remain neutral and nonjudgmental across diverse perspectives, relationships, belief systems and worldviews, and to explain the reasoning behind a professional judgment.

- Working familiarity with concepts such as sycophancy, cognitive distortions, healthy boundaries and client centered approaches such as motivational interviewing.

- Ability to engage reliably for at least 20 hours/week during weekdays.

- Strong written communication skills and the ability to deliver precise, well structured written feedback.

**Nice to have:** a background in AI safety, applied ethics, trust and safety or content policy; experience in couples, family or relationship counseling; familiarity with spiritual care, religious or alternative belief communities, or the psychology of misinformation and conspiracy belief; prior experience evaluating, annotating or red teaming AI systems.
