What you'll do:- Plan and ship a weekly content calendar across LinkedIn, Instagram, X, TikTok and YouTube.- Write social posts and captions in Arkintel's voice: sharp, sovereign, opinionated, never marketing-mush.- Capture photo and video at talks, keynotes, customer site visits and around the studio in Delft.- Edit short-form video (Reels, Shorts, TikTok) and longer-form keynote highlights for YouTube.- Track what works (impressions, follower growth, qualified inbound) and iterate the calendar accordingly.- Co-own one or two campaigns end-to-end — from brief to publish to retrospective. Who you are:- A student or recent grad in marketing, communications, design, journalism or something tangential. We care about the work, not the degree.- You actually use the platforms you'd be posting on, and you have opinions about what's good.- You can write in English that sounds like a person, not a brand voice generator.- Comfortable with a camera, basic photo / video editing (CapCut, Premiere, Lightroom, Figma).- Self-directed; you don't need a brief for every post.- Bonus: Dutch language skills, since a lot of our customers and partners are Dutch. What you get:- Hands-on ownership of Arkintel's social channels: planning, copy, capture and publish.- Work alongside the team on real talks, demos and customer visits.- Reference or recommendation and study credit where your programme requires it.- Tools and a desk in Delft; travel to events when we're there together.
