Social Media (1)
Requirements
  • Crypto obsessed (or at the very least, extremely curious and willing to learn more)
  • Deep industry knowledge (you know, or better yet, regularly use web3 apps and have a strong perspective on what works and what doesn’t in web3 marketing — especially pertaining to social-first viral campaigns)
  • Experience creating high-volume content for social media platforms like X (primarily), and LI/IG/YouTube/TikTok/Warpcast (secondary)
  • Experience with end-to-end management of social platforms — from posting to analytics social listening (bonus points if you understand Kaito and yap for breakfast)
  • A team player who loves collaborating as much as they do owning something individually from start to finish — and knows when and how to get the most out of others. Both independent hustle and dream team vibes.
  • The ability to balance, evergreen content, product-marketing, and creative campaigns — and do so with Messi-esque agility
  • An interest (or experience) in “founder-led” social media
  • Technical expertise (or a very sponge-like brain). If you have a specific lane of technical expertise, that’s cool, but we expect you have a thirst for knowledge across different use cases
  • An open mind and ability to take feedback — and run with it!
Responsibilities
  • Manage the social media strategy, operations, and execution for 3-5 Serotonin clients.
  • Ability to write in multiple voices; from informative to humorous and lighthearted - able to tailor messaging to platform in line with client’s branding.
  • Leverage data and social media marketing tools to analyze areas of weakness in order to grow internal serotonin and client brands.
  • Maintain both a consistent understanding and a strong pulse of the current events within the web3 ecosystem.
  • Work closely with the Social Media Director and SVP of Content, Community, and Social as well as the client Marketing Directors to develop social strategy and proactively ideate new social opportunities for clients.
  • Create and maintain account management systems to operationalise scheduling, posting, and replying.
  • Work closely with the content and community team to plan and execute owned marketing campaigns.
  • Collaborate cross functionally with PR, events, community, marketing, growth ensuring content remains consistent and aligned.
  • Strategize, operate, and execute other social media activities such as: Twitter Spaces, AMAs, giveaways, and growth campaigns.
  • Remain well-versed in the social strategies of other technology and product teams.
Desired Qualifications
  • And most importantly..
  • An unquenchable thirst for crafting compelling, insanely creative content that simplifies products, converts & engages audiences, fuels growth and mindshare, taps into trends (or creates new ones) and stops scrollers in their tracks and makes them go ‘damn’.
  • Whether you were born in the trenches on Crypto Twitter, degened your way out of one too many rugpulls, or caught the web3 bug while creating content at an award-winning advertising agency, tech startup, or while building your own personal brand — we’re looking for creative swiss-army knives who treat every touchpoint as an opportunity to dazzle clients and users.
  • We’re also especially excited to talk to candidates who have experience (and/or a rapidly growing interest) in creating multimedia content with the help of cutting edge AI tools, as well as familiarity with the Adobe Photoshops of the world, to bring short, snackable videos, memes, graphics, podcast clips, and on, to life.
  • If you can as effortlessly craft a banger (i.e., technically accurate and compelling) Twitter thread on ZK proofs as you can create an AI video of Vitalik riding a Unicorn, we want to talk.

Web3 Gaming Sucks: The Struggle With User Experience

For years, playing video games was relatively simple. You turned on your computer or console, booted up your game of choice, loaded a previous save (or jumped straight into online play), and had fun. However, within the last year or so, a new library of terms has entered the lexicon. Whether it’s play-to-earn, play-to-own, wallet, GameFi, or the much-maligned ‘NFT,’ gaming is becoming a little more complicated
