Chrome Extension Developer for Secure AI Workflow Automation

We are looking for an experienced developer to help build a secure Chrome browser companion tool for a professional services workflow. The extension will connect to an internal client portal, receive approved client intake data, detect approved pages inside a third-party web application, and assist with draft-filling visible form fields for human review. This is not a scraping, credential-sharing, or security-bypass project. The extension must work inside the user’s approved browser session and respect all third-party login, MFA, security, and compliance boundaries.
