UK-Based Video Producers & Editors

**About this study**

Mercor is building a new, more accurate version of O\*NET — the U.S. government's framework for describing occupations and the tasks they involve. We are gathering input directly from experienced practitioners to improve how the work of software developers is described.

**About the role (SOC 15-1252.00 — Software Developers)**

Software developers research, design, and build computer software, network software, or specialized utility programs. They analyze user needs, determine the feasibility of designs within time and cost constraints, and develop software solutions by applying principles of computer science, engineering, and mathematical analysis. Their work spans the full development lifecycle: defining specifications and performance requirements, architecting systems, directing testing and validation procedures, and modifying existing software to correct errors, adapt to new hardware, or improve performance. They may coordinate with hardware engineers to integrate hardware and software systems, and they often own decisions about system design rather than executing designs handed to them.

**This occupation excludes**

- **Web developers (15-1254.00)**, whose work centers on developing and implementing websites, web applications, and interactive web interfaces. A worker whose primary responsibility is building or maintaining websites, optimizing website performance, or integrating websites with other applications is a web developer, even if they write substantial application code. The distinguishing test is the artifact: web developers produce web properties; software developers produce software systems and applications more broadly, of which the web may be one deployment surface among many.
    
- **Computer programmers (15-1251.00)**, who create, modify, and test code working from specifications drawn up by software developers or others. The distinguishing test is authorship of the design: programmers implement designs they are given, while software developers analyze requirements, produce the design, and direct development. A worker who primarily writes and debugs code to someone else's specification is a programmer, not a developer.
    

**What you'll do**

- Complete a one-time online survey/interview about your day-to-day work as a software developer. It takes **up to 30 minutes**.
    
- There may be an optional follow-up survey, task, or short interview afterward, which would be paid separately.
    

**Who we're looking for (eligible applicants have)**

- **4+ years of experience working specifically as a software developer.**
    
- **Current work, or work within the last 12 months, in the role.**
    
- **Direct knowledge of design, coding, and deployment tasks.**
    
- **U.S.-based.**
    

**Not eligible (common confounders)**

- Software QA analysts and testers whose role is testing rather than development (SOC 15-1253.00).
    
- IT support, help desk, or system administrators who do not develop software.
    
- Computer programmers (SOC 15-1251.00).
    
- Web developers (SOC 15-1254.00).
    
- Computer systems analysts (SOC 15-1211.00).
    
- Computer systems engineers (SOC 15-1299.08).
    
- Computer and information systems managers (SOC 11-3021.00).

Performance Engineer (C++, Python, Rust)

## About the Opportunity

A leading AI research organization is seeking advanced LLM power users with strong experience using MCP and (more importantly) plugins/connectors for real-world personal life tasks.

This project focuses on evaluating how well AI systems handle personalized, multi-step life tasks that require context, judgment, planning, and use of connected tools such as Google Drive, Expedia, Notion, and other plugins/connectors.

This role is ideal for people who use AI heavily in their personal lives and can do a better job replicating what AI could do if it weren’t available

## What You’ll Do

You will help evaluate AI systems on complex personal workflows, including tasks across:

- Personal health
    
- Travel
    
- Activity planning, including food and dining
    
- Services, such as home repair
    
- Career search
    
- Other life organization workflows
    

Responsibilities may include:

- Creating realistic prompts for complex personal-life tasks
    
- Executing tasks and actions while recording your screen (required)
    
- Using your personal plugins/connectors while you complete actions
    
- Writing clear explanations of AI successes and failures
    
- Judging whether AI outputs are practical, personalized, and well-reasoned
    
- Identifying where models miss context, overreach, fail to use tools correctly, or produce unrealistic results
    
- Creating and applying detailed rubrics to assess model performance
    

## Who We’re Looking For

Strong candidates will have:

- US-based only
    
- Strong MCP experience and plug in / connector usage
    
- Experience using LLM plugins/connectors such as Google Drive, Expedia, Notion, and similar tools, multiple times a week
    
- Heavy personal usage of LLM products
    
- An active, rich LLM account with regular usage and approximately 6+ months of history
    
- **Willingness to sign a data-share consent form via DocuSign**
    
- Experience using AI for multi-step planning, research, decision-making, or personal workflows
    
- Strong written judgment and attention to detail
    
- Ability to explain what makes an AI output good, bad, incomplete, unsafe, or unrealistic
    
- Experience writing and evaluating against rubrics
    

Extensive rubric experience is especially valuable, including 100+ hours on prior rubric projects involving rubric design, evaluation, and quality assessment.

## Ideal Candidate Profile

The strongest candidates are LLM power users who are already using plug-in tools in their personal lives for high-context tasks such as trip planning, health research, home services, food and dining decisions, career planning, personal organization, or similar workflows.

Candidates who want to be more competitive for this and future opportunities are encouraged to proactively spend time learning MCP and using LLM plugins/connectors before applying.

## Why This Work Matters

LLMs are quickly becoming personal assistants for everyday decisions, but truly useful AI needs to do more than produce generic advice. It needs to understand context, preferences, constraints, tradeoffs, and what success looks like in real life.

Your evaluations will help improve how AI systems support people with practical, high-context tasks across food, health, travel, productivity, careers, and life organization. This work directly contributes to making AI assistants more personalized, trustworthy, and useful for real-world personal workflows.

## Engagement Details

- Expected commitment: 20+ hours/week
    
- Ramp-up: 1–2 days required
    
- Turnaround expectation: Ability to complete tasks within 24 hours
    
- Equipment: Desktop or laptop required; Chromebooks are not supported
    
- Experts added to the project will begin in a trial period to assess project fit, quality, and consistency before being considered for ongoing tasking.

AI Rater Guidelines Writer (Linguist / Instructional Designer)

We are recruiting a select cohort of accomplished physics researchers to contribute to the next generation of AI systems for scientific reasoning. Our partner labs are building models that need to reason about theoretical physics, condensed matter, quantum information, particle physics and high-energy theory, astrophysics and cosmology, atomic/molecular/optical (AMO) physics, plasma physics, biophysics, statistical and computational physics, and mathematical physics at the level of a working researcher — not a textbook. To get there, they need contributors whose own research sits at the frontier.

This position will be placed at a leading AI lab as part of their extended workforce.

## What you'll do

- Review and evaluate research papers in physics for correctness, novelty, and significance
- Author and review challenging physics problems used to train and evaluate frontier AI models
- Evaluate model outputs on tasks ranging from analytical derivation and mechanism prediction to numerical modeling, experimental design, and literature reasoning
