About the job We are seeking a Technical Content Creator to showcase the practical power of Tether's peer-to-peer stack. This is a builder-centric role designed for an engineer or highly technical creator who bridges the gap between low-level infrastructure, cryptography, and functional application.We are not looking for a social media marketer or an on-camera influencer. We are looking for a technical storyteller who can write code, spin up peer-to-peer nodes, build functional Bare-powered applications, and record polished, clear, screen-share demos. You will turn our core stack (Pear and Bare) into an ongoing series of visual, practical "build-in-public" prototypes that prove to the world what true decentralized, peer-to-peer infrastructure looks like.Responsibilities Build Practical Demos: Independently build functional peer-to-peer applications and infrastructure setups using the Pear platform and the Bare runtime with minimal engineering hand-holding. Record Technical Demos: Record clear, engaging, and high-quality screen-share walkthroughs and video demos of your builds, highlighting how the code works, how peers discover and sync with each other, and the value the systems deliver. Translate Code to Content: Turn complex protocol updates, cryptographic primitives, and technical documentation into highly visual, digestible developer content (such as code-along videos, step-by-step guides, and interactive repositories). Collaborate with Core Devs: Work closely with our P2P protocol and product engineering teams to stay ahead of upcoming Pear and Bare features. Prototypes: Rapidly prototype application concepts — such as spinning up a peer-to-peer chat, file-sync, or data-replication demo — to show how quickly developers can launch resilient, serverless products using our ecosystem. Fuel Influencer-Led Developer Adoption: Collaborate with technical influencers, developer advocates, and content creators to amplify our ecosystem. You will provide them with turn-key technical assets, co-create code-along challenges, and arm them with the high-quality demos and prototypes needed to inspire and onboard new developers to Pear and Bare.
