About d-Matrix

d-Matrix is the semiconductor company pioneering low-latency AI inference for data centers. The company has a current valuation of $2 billion, having raised $450M from investors including Microsoft's M12, Temasek, Samsung, SK Hynix, the Qatar Investment Authority, and Singapore's EDBI. Corsair, the company's flagship inference accelerator, is in full production and shipping to hyperscalers, neoclouds, and frontier AI labs.

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.

Key Responsibilities

Media Relations

• Own day-to-day media relations: proactive pitching, inbound inquiry management, and relationship building with reporters covering AI, semiconductors, cloud infrastructure, and enterprise technology

• Develop and execute press releases, pitches, media kits, talking points, and press briefings

• Build and maintain a targeted media list spanning tier-1 business press (CNBC, Bloomberg, Reuters, WSJ), tech press (WIRED, The Verge, The Information), and trade publications (EE Times, The Next Platform, HPCwire, Tom's Hardware)

• Arrange spokesperson opportunities, including deskside briefings, conference 1:1 interviews, media tours, podcast appearances, and analyst days

• Monitor coverage, track sentiment, and report on media impact
  

Agency Management

• Manage day-to-day relationships with Aircover Communications, d-Matrix's external PR agency

• 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

• Over time, develop and manage contractual arrangements with analysts and influencers for third-party content, market intelligence, and positioning guidance
  

Awards & Recognition

• Identify and manage award submissions across industry programs (TIME Best Inventions, Fast Company Next Big Things, GSA Startup to Watch, AI Breakthrough Awards, etc.)

• Track deadlines, draft applications, and coordinate with cross-functional teams for supporting materials
  

What You Bring

• 7-10 years of experience in public relations, media relations, or corporate communications—ideally in semiconductors, AI, cloud infrastructure, or enterprise technology

• Proven experience managing external PR agencies and holding them accountable for results

• Strong, existing relationships with technology reporters at major business and trade publications

• 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

• Experience supporting C-suite executives with communications materials and media preparation

• Comfort working in a fast-paced startup environment where priorities shift quickly and resourcefulness matters more than process

• Strong news judgment, i.e., you know what's a story, what's not, and how to frame the difference

• Familiarity with AI, semiconductor, or data center markets is strongly preferred
  

What We Offer

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

• Direct access to the CEO and leadership team. Your work will be visible and have high impact from day one

• Competitive salary, equity, and benefits

• A collaborative, growth-minded team that values strategic thinking and editorial excellence
