**Joyride** is building the first dedicated 0DTE options exchange to provide better leverage for crypto traders. Derivatives present the single largest opportunity to bring traditional finance on-chain with over $3.5 trillion dollars of notional volume traded in the U.S. every day. We are developing the fastest, most exciting exchange in history and looking for a **Head of Growth** who knows how to bootstrap a community from 0 to 1 (million users). ## The Team You will be joining a founding team with a proven track record of building successful companies on-chain and off. Joyride’s team includes the founders and early contributors of Origin Protocol, where we’ve been building on Ethereum since 2017 and have scaled products to nine-figure TVL. In addition to being early advisors to Solana, two of Joyride’s cofounders have built and worked multiple venture-backed companies that have been acquired by Google, Yahoo, and Walmart. ## The Challenge 0DTE options have taken Wall Street by storm: retail traders alone generate $1 TRILLION per day of notional volume. But they haven’t yet reached escape velocity in crypto. We’re here to change that. As our first non-engineering hire, your mandate will be to orchestrate a movement. You will work directly with the founders to define the Joyride brand—a mix of high-finance precision and WallStreetBets chaos. You will own the funnel from the first content post to the first deposit. ## What you will do: * **Narrative Warfare:** Own the story across X, TikTok, Reddit, and Discord, positioning Joyride not just as a product, but as the only venue for serious on-chain leverage. * **The Degen Loop:** Design and execute referral programs, trading competitions, and leaderboard mechanics that incentivize viral sharing of P&L. * **KOL & Influencer Strategy:** You know who moves markets in Crypto and TradFi. You will build relationships with key opinion leaders, not by paying them for shills, but by getting them addicted to our product. * **Data-Driven Hype:** Monitor on-chain analytics and community sentiment. You understand that volume is our north star metric. * **Launch Orchestration:** Plan and execute the genesis launch event. Manage the waitlist mechanic to create scarcity and FOMO. ## Who you are: * **Terminally Online:** You know the memes before they land. You understand the culture of WallStreetBets, Crypto Twitter, and blockchain ecosystems. * **Growth Hacker:** You’ve grown a Discord server to 50k+ or a Twitter account to 100k+ and you understand viral loops. * **Scrappy:** You are willing to grind and do what it takes to generate results without a big company budget. ## Requirements: * Proven track record in Web3 marketing or high-growth fintech * Deep understanding of various blockchain ecosystems * Ability to work in a chaotic, fast-paced environment * Connections to trading communities and experience in the trenches * Familiarity with AI content generation ## Bonus: * Knowledge of 0DTE and options concepts * A following and positive reputation in the WallStreetBets community * Experience with Veo 3 or equivalent AI content generation ## What we offer: * Competitive salary and upside * Remote work flexibility * Autonomy to solve challenging problems * Fast-paced environment * Unlimited growth potential * A platform for personal growth When applying, mention the word **CANDYSHOP** to show you read the job post completely.

## Founding Principal Engineer Joyride is building the first dedicated 0DTE options exchange to provide better leverage for crypto traders. Derivatives present the single largest opportunity to bring traditional finance on-chain with over $3.5 trillion dollars of notional volume traded in the U.S. every day. We are developing a world-class exchange using a hybrid architecture: a central limit order book (CLOB) for low latency execution coupled with a blockchain for transparent, non-custodial settlement. ### The Team You will be joining a founding team with a proven track record of building successful companies on-chain and off. Joyride’s team includes the founders and early contributors of Origin Protocol, where we’ve been building on Ethereum since 2017 and have scaled products to nine-figure TVL. In addition to being early advisors to Solana, two of Joyride’s cofounders have built and worked for multiple venture-backed companies that have been acquired by Google, Yahoo, and Walmart. ### The Challenge 0DTE options have massive “Gamma risk”—prices move violently as expiration approaches. This presents a unique challenge for an exchange to operate safely. - **Balancing Solvency & Capital Efficiency**: Our portfolio margin engine must ensure that traders can always meet the obligations to their counterparties while minimizing the amount of collateral they’re required to post. - **Execution Speed**: To efficiently provide liquidity and avoid toxic flow, market makers need to update orders in milliseconds. Even the fastest blockchains today are too slow. - **Trust & Verifiability**: Traders demand self-custody and transparency. They won’t deposit funds into a black box they don’t control. - **Availability**: Global capital markets never sleep. Our exchange must be dependable and reliable, enabling traders to execute orders and withdrawals 24/7. As our Founding Principal Engineer, your mandate will be to solve this difficult challenge. You will architect a hybrid exchange engine that matches orders off-chain at the speed of light but settles them on-chain with cryptographic proof of validity. ### What You Will Build - **The Trusted Matching Engine**: Architect a high-frequency Central Limit Order Book (CLOB). It must handle massive throughput without the latency drag of a blockchain while maintaining verifiability. - **The Trust Bridge**: Design the cryptographic system that proves to the blockchain that the off-chain match was valid. We must ensure that the exchange operators cannot front-run or alter the order book. - **Atomic Settlement**: Write the programs that handle the movement of collateral based on the proofs generated by your off-chain engine. - **Risk & Liquidation**: Build a real-time risk engine capable of liquidating 0DTE positions instantly to protect the protocol from bad debt, even during high network congestion. ### Who You Are - **High-Performance Systems Expert**: You understand exactly how your code maps to hardware. You prioritize memory layouts, lock-free data structures, and concurrency patterns to squeeze every cycle out of the CPU. - **Architectural Polymath**: You are comfortable traversing the gap between high-performance cloud infrastructure and trustless state machines. - **Security Minded**: You think like an adversary. When you see a “hybrid” architecture, your first thought is “How do I break the link between the server and the chain?” ### Requirements - 5+ years of backend systems engineering (Rust, C++, or Go) - Deep proficiency with Rust - Familiarity with Solana and EVM development - Knowledge of event-driven architectures and asynchronous programming - Experience designing hybrid architecture - Strong grasp of applied cryptography ### Bonus - Experience building trading systems (matching engines, risk management) - Background in high-frequency trading or financial engineering - Previous work on a centralized exchange or CLOB DEX ### What We Offer - Competitive salary and upside - Remote work flexibility - Autonomy to solve challenging problems - Fast-paced environment - Unlimited growth potential - Support for open-source contributions When applying, mention the word **CANDYSHOP** to show you read the job post completely.
