• Ensure consistent messaging across every touchpoint, from website and social to partner co-marketing and events
• Plan and execute RadixArk's field programs end to end, including developer meetups, partner activations, and industry conference presence
• Own agenda, speakers, vendors, on-site execution, and post-event follow-up, not just the brief

• Build relationships with media, analysts, and technical influencers
• Assess quickly whether and how to respond to sensitive situations, set the right framing and channel, and write the response yourself
