The Role
We are looking for a creative content creator and social media expert to help create and shape our social media presence.
This includes creating engaging posts, short-form videos, reels, TikToks, platform comparison content, educational content, and community-focused content for the CS2 audience.
We already have some content ideas, but we want the right person to bring their own creativity, strategy, and personal touch. You will have room to help define the style, tone, and direction of our social media.
This role is ideal for someone who understands gaming culture, Counter-Strike 2, skins, trading, gambling platforms, memes, trends, and short-form content.
Responsibilities
Create social media content for platforms such as X/Twitter, TikTok, Instagram, YouTube Shorts, and other relevant channels
Produce posts, graphics, short videos, reels, and platform comparison content
Help develop a consistent brand voice and content style
Turn CS2 trading and gambling platform comparisons into engaging, easy-to-understand content

Strong English communication skills
Experience with tools like CapCut, Premiere Pro, Canva, Photoshop, Figma, or similar is a plus

Budget & Workload
We are open to discussing either a fixed monthly arrangement, per-content pricing, or an hourly setup depending on your experience and proposed workflow.
Please include your expected rate, availability, and what type of content package you can offer.
