Build a sourcing string from titles, skills and exclusions, then copy the version for the site you are searching. Free, no signup, and nothing you type leaves your browser.
("product engineer" OR "full stack engineer" OR "software engineer") AND typescript AND react AND (postgres OR next.js) AND Berlin -recruiter -staffing -internBalanced string. If results are thin, drop one required term before you touch the titles.
Drop them straight into a pipeline with the source attached, instead of a spreadsheet tab called sourcing final v3.
Run the titles alone first. Add required skills only once you can see what the noise actually is.
Two word terms without quotes match each word separately, which is where most bad result sets come from.
Every exclusion also removes people who merely mention the word. Cut agencies and unrelated titles, not skills.
