New filter: Seniority Level

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, click + Add Filter, and select Seniority Level. Pick one or more levels and the results update instantly.

    "job_seniority_or": ["junior"],
    "posted_at_max_age_days": 30,

  }'
