- Activate the Harmattan AI brand for U.S. audiences and own U.S. positioning for the product portfolio
- Build and maintain a library of U.S. collateral (capability briefs, white papers, customer presentations) and create repeatable processes for rapid production
- Translate complex technical capabilities into clear, accurate messaging for operational and acquisition audiences
- Direct photo and video capture at demonstrations to produce compelling visual storytelling
- Own U.S. public relations and earned-media strategy, building relationships with defense media and analysts
- Execute U.S. events and trade-shows across defense conferences, symposiums, and demonstrations

- Build U.S. employer-branding and digital campaigns supporting Austin operation growth
- Define U.S. marketing KPIs tied to pipeline, customer engagement, recruiting, and market credibility
- Manage agencies, contractors, and event vendors; build the future U.S. marketing team
REQUIREMENTS:
- Significant experience building or scaling marketing at a U.S. defense technology, aerospace, autonomy, or national security company
- Experience in a high-growth defense technology environment strongly preferred
- Deep fluency in the U.S. national security ecosystem and credible communication with defense audiences
- Proven ability to market sophisticated technology accurately, without buzzwords or overclaiming capability
- Track record across product marketing, executive communications, event strategy, thought leadership, and sales enablement
- Hands-on operator who personally produces work at speed, rather than only managing agencies or teams
- Experience working with veterans, engineers, operators, and government customers highly valued
- Strong portfolio of prior work required; relevant bachelor's degree preferred but secondary to demonstrated performance
- Full commitment to Harmattan AI's mission and readiness to thrive in fast-paced, high-pressure environment
