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.

• Set priorities, review agency deliverables, and ensure agency output aligns with corporate messaging and brand voice
• Collaborate with the VP on agency strategy, scope, and performance evaluation

Executive Communications Support

• Support the VP in preparing CEO and executive communications: interview prep documents, briefing materials, talking points, and speech drafts
• Help develop and maintain messaging frameworks aligned with the company’s narrative
• Draft and edit CEO social media posts for LinkedIn in coordination with the VP

Industry Analyst & Influencer Relations (Scaling Over Time)

• Begin building relationships with key industry analysts covering AI infrastructure and semiconductors
• Identify and engage with targeted industry influencers and creators, equipping them with content and access to d-Matrix spokespeople

• Excellent writing and editing skills with ability to draft a press release, a CEO LinkedIn post, and an interview prep doc all in the same morning

• A seat at the table in a company that is defining a new category in AI infrastructure
