Communications and Marketing Manager

Most communications and marketing roles are about telling the story.

This one is about helping create the category.

We're looking for a Communications & Marketing Manager to work directly with me and our leadership team as we build what will become the next generation of AI data center infrastructure.

This role sits at the intersection of engineering, product, customers, media, and leadership. It's ideal for someone who enjoys making deeply technical work understandable without sacrificing accuracy.

If you're excited about building a category, not just marketing within one, we'd love to hear from you.

Job Description

We're hiring a mid-level to upper-level Communications & Marketing Manager to own the day-to-day execution of Karman's external voice and internal alignment as we scale from early commercial deals into a category-defining company. This is a builder's role: you'll work directly with the CEO and leadership team to turn deeply technical, fast-moving work (customer deals, product milestones, engineering breakthroughs) into clear, credible communications — both to the outside world and across our own team.

You won't be starting from zero — there's an existing point of view, a growing library of technical narrative, and senior leadership deeply engaged in comms. What we need is someone who can take that raw material and turn it into consistent execution: content calendars, drafts, internal updates, press coordination, and event/launch logistics.

Responsibilities

• Brand & category building: Support the "category creation" mandate for sCO₂ thermal infrastructure — help establish Karman's voice as the default reference point in a market segment that's still being defined. Partner with external creative agencies as needed.
• Founder & executive content: Draft and refine social media posts, announcements, blogs, and talking points in the company's voice — plain, facts-first, substance over rhetorical flourish. Turn technical updates (product milestones, funding news, customer wins) into clear external narrative.
• Press & external relations: Coordinate press releases (e.g., BusinessWire), manage media inquiries, and help build relationships with national and trade press covering data center infrastructure, semiconductors, and AI capex.
• Internal communications: Own regular internal updates that keep a fast-growing, distributed team aligned across company milestones, org changes, culture and recognition moments.
• Launch & event support: Help plan and execute moments like factory facility opening, award announcements, and customer/investor-facing events.
• Marketing operations: Manage content calendars and maintain brand consistency across decks and collateral.

Required Qualifications:

• 3–6+ years of experience in communications, marketing, or content roles, ideally at a startup, deep tech, industrial, or infrastructure company where you had to make technical work legible to a broad audience.
• Excellent writer with a track record of shipping clean, clear copy fast, someone who can match an established voice rather than impose a new one.
• Comfortable working directly with a CEO and technical leadership; able to extract the substance from an engineering conversation and turn it into a sentence a customer or investor will actually read.
• Experience with press coordination, LinkedIn/executive ghostwriting, agency or freelancer coordination, or B2B content marketing.
• Organized self-starter - this role covers a wide surface area (internal + external, written + event) and requires prioritizing without much hand-holding.

Preferred Qualifications:

• Familiarity with data centers, semiconductors, energy infrastructure, or industrial/hardware startups.
