# Lynceus Open Job Index

**246,443 open roles** at **7,118 companies**, **46,473** of them
remote. Read directly from each employer's own careers page and public ATS
feed — never aggregated or reposted from a job board.

_Last updated: 2026-09-15 04:19 UTC_

## What this is

Most job datasets are scraped from aggregators, which means they are a copy of
a copy: stale, deduplicated badly, and full of listings that were filled weeks
ago. This one is read at the source — each employer's own ATS feed — and a
listing is removed when the company takes it down, so the set does not
accumulate filled roles.

**This is a labour-market dataset, not a job board.** It tells you who is
hiring, for what, where, and when the role was posted. It deliberately does not
carry apply links: the URL of a posting also identifies the employer's job
board, and the mapping of company to board is the part of this that took real
work to build. Searching and applying happens in the product.

## Configs

| Config | Rows | What it is |
| --- | --- | --- |
| `jobs` (default) | 246,443 | One row per open role |
| `companies` | 7,118 | One row per employer, with its open-role count |

```python
from datasets import load_dataset

jobs = load_dataset("Lynceus/jobs", "jobs", split="train")
companies = load_dataset("Lynceus/jobs", "companies", split="train")
```

## Fields

### `jobs`

| Field | Type | Notes |
| --- | --- | --- |
| `title` | string | The role, as the employer wrote it |
| `company` | string | Employer name |
| `location` | string | Free text, as published — not normalised |
| `remote` | bool | Marked remote by the employer |
| `posted` | date | `YYYY-MM-DD`; empty when the source omits it |

### `companies`

| Field | Type | Notes |
| --- | --- | --- |
| `company` | string | Employer name |
| `open_roles` | int | Open roles at export time |

## What is excluded, and why

- **Recruiters, staffing agencies and job-board aggregators.** Every entry is an
  employer hiring for itself.
- **Companies with no career page or no open role.** There would be nothing to
  apply to.
- **Non-commercial domains** — `.org`, `.edu`, `.gov` and similar.
- **Job descriptions.** They are the employer's own copyrighted text, and
  republishing them wholesale is not ours to do.
- **Apply URLs and careers-page links.** See above — a posting URL identifies
  the employer's job board, and that mapping is not published.
- **Roles found by scraping a company's careers page** rather than reading an
  ATS feed. Those stay in the product.

## Known limitations

- `location` is free text exactly as the employer published it, so `London`,
  `London, United Kingdom` and `London, GB` all occur. Normalise before
  aggregating.
- `posted` is missing for a minority of rows, because not every ATS feed
  publishes it. Sort with nulls last.
- Company names originate from ATS tokens for board-sourced employers, so some
  appear as slugs (`Openai` rather than `OpenAI`).
- Coverage skews toward companies using Greenhouse, Lever, Ashby, Workable and
  similar modern ATS platforms.
- Without a URL, a row cannot be de-duplicated against another dataset or
  followed to the posting. That is a real cost of the trade above and worth
  stating rather than discovering.
