You can now filter job postings by seniority level, both in the app and the API.

We classify every job into one of five levels: **Junior**, **Mid-level**, **Senior**, **Staff**, and **C-level**. This lets you narrow results to the experience band you care about without relying on keyword tricks in the job title or description.

#### In the app

Open [Job Search](https://app.theirstack.com/search/jobs/new), click **\+ Add Filter**, and select **Seniority Level**. Pick one or more levels and the results update instantly.

#### In the API

Use the `job_seniority_or` parameter in the [Jobs API](/en/docs/api-reference/jobs/search_jobs_v1) or the [Company Search API](/en/docs/api-reference/companies/search_companies_v1):

```
curl -X POST https://api.theirstack.com/v1/jobs/search \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "job_country_code_or": ["US"],
    "job_title_or": ["software engineer"],
    "job_seniority_or": ["junior"],
    "posted_at_max_age_days": 30,
    "limit": 10
  }'
```

Accepted values: `junior`, `mid_level`, `senior`, `staff`, `c_level`.
