About the Role
The senior manager of public relations is the first dedicated PR hire at d-Matrix, joining a corporate communications function that reports directly to the CEO. You'll be the person who turns d-Matrix's technical breakthroughs into headlines, owning media relations; managing external agencies; building analyst and influencer relationships; and supporting executive communications.
This is a rare opportunity to join a company at the exact moment its narrative is breaking through with major media outlets, including CNBC, Reuters, and Bloomberg, as well as major trade press already covering the story.
This is a hands-on role. You'll be pitching reporters, writing press releases, prepping the CEO for interviews, and managing agency output, all while helping build the PR function to its full potential. If you want to be the person who shapes how the world discovers a category-defining AI infrastructure company, this is the job.
