About this role

PHP, JavaScript, Web Scraping, User Interface / IA, Software Architecture, Google Chrome, Software Development, Web Development, API Integration, Software Engineering · We need a single Manifest V3 browser extension that installs cleanly on Chrome and Microsoft Edge.

The extension will detect duplicate candidates while reviewing or creating a candidate in Workday or SAP Fieldglass by comparing the candidate’s email address and phone number against existing records.

Core Features Auto-scan: Automatically check the candidate when the page loads. Manual scan: Toolbar button to trigger a duplicate check on demand. Matching: Exact match on email OR phone number. Display a clear visual alert showing which field matched. Provide a deep link to the existing candidate profile, where available. Lightweight UI with a simple banner/icon badge and easy future branding.

Technical Requirements Chrome + Microsoft Edge compatible Manifest V3 JavaScript or TypeScript Content scripts may extract data from Workday/Fieldglass; APIs may be used where available. No modifications to Workday or Fieldglass. All processing must remain client-side; no candidate data may be stored or sent to an external server. Clean, well-commented, maintainable code with zero console errors.
