Search current US federal job postings via the USAJobs API. Filter by keyword, positionTitle, locationName ("Washington, DC" or city/zip), remote (telework-eligible), pay grade range (e.g. payGradeLow=GS09 + payGradeHigh=GS13), jobCategoryCode (occupational series, e.g. 2210 for IT), organization (agency sub-element code, e.g. TR40 for IRS), whoMayApply (all/public/status). Returns per-posting: control number, position ID, title, USAJobs URL + apply URL, organization + department, locations, schedule, offering type, pay scales (min/max + interval), publication start + application close, qualification summary, job category + grade. Use sortField + sortDirection to sort. Pagination via resultsPerPage + page.
