**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).

**Nepali Music Expert**

Mercor is hiring music experts for a frontier generative-music AI lab, working in **Nepali**.

We're looking for someone with formal musical training or professional experience — a degree in music, or a few years working as a musician, composer, transcriber, engineer, or teacher. You should have a strong ear: the hardest part of the work is transcribing a melody by ear with relatively accurate pitch and rhythm, and recognizing key, tempo, and time signature.

For **Nepali**, you also need strong fluency so you can accurately handle sung lyrics — including accents and less-clear delivery.

This is a pilot at **2–5 hrs/week**, but it is very likely to expand, and high performers will be prioritized for the larger phases.

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
- Surface areas where current models fail — especially the kinds of mistakes a working PhD physicist would catch immediately
- Collaborate with a small program team and other senior contributors

## Qualifications

We're looking for researchers who meet several of the following:

- First-author or co-first-author publications in journals such as Physical Review Letters, Physical Review X, Reviews of Modern Physics, Nature Physics, Nature, Science, PNAS, Nature Communications, the Physical Review A/B/C/D/E family, Physics Letters B, the Journal of High Energy Physics, the Astrophysical Journal, Monthly Notices of the Royal Astronomical Society, Quantum, or Communications Physics
- A doctorate or postdoctoral training from a top-20 global institution in physics or a related STEM field
- A competitive fellowship, such as an NSF Graduate Research Fellowship, a Hertz Fellowship, a DOE Computational Science Graduate Fellowship, a DOE Early Career award, a Sloan Research Fellowship, a Packard Fellowship, a Simons Investigatorship or Junior Fellowship, a Hubble, Einstein, Sagan, or Kavli (KITP) Fellowship, a Marie Curie/MSCA award, a Fulbright, Rhodes, Marshall, Gates Cambridge, or Schmidt Science Fellowship, an NSF CAREER award, or an APS Fellowship
- Issued patents, a spin-out company, or grants held as a named Principal Investigator or Co-Investigator
- An International Physics Olympiad (IPhO) Gold, Silver, or Bronze medal
- Current or recent experience in an active research role, as a PhD candidate, postdoctoral researcher, instructor, faculty member, principal scientist, or industry researcher; current title matters — we prioritize active faculty, postdoctoral researchers, or PhD candidates over general staff research-scientist titles

Outstanding senior PhD students and recent graduates with strong publication records are strongly encouraged to apply; the depth of your research output matters more than years of experience.
