At Zenni Optical, people remain the heart of our mission, even as we embrace technology that moves us forward. While we recognize the immense promise of AI, we are equally mindful of its limitations and use these tools strictly to assist our Talent Acquisition team rather than replace human judgment. We utilize AI tools as a collaborative partner to create content-such as job descriptions, interview questions, and outreach messaging-and review resumes, but we maintain a firm commitment to human-led hiring where AI never makes a final decision. Every selection is determined by a member of our team to ensure every candidate is personally valued by a human rather than an algorithm.

We look forward to hearing from you!
