We're looking for a Senior Brand Design & Content Manager to own Radiant's day-to-day content production across social media, presentations, and visual assets. You'll write and post social content for the company and executives, build slides and decks, create graphics, and produce the content packages that accompany every milestone. This is a high-output, hands-on role—you're not directing from above, you're in Canva at 4pm making tomorrow's LinkedIn post.
The ideal candidate is a fast-moving content creator who can write punchy social copy, design clean visuals, and adapt voice across multiple executives. You understand that in a world of AI-generated content, authentic voice and visual quality matter more than ever. You also understand that "nuclear" comes with baggage, and you know how to reframe the conversation around what microreactors actually are: small, safe, portable, and fundamentally different from the legacy plants people fear.
