## 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.

## Company Description We are pausing travoom to focus on **oleolesport.com**. OleOle is developing a completely free social network and messaging platform for football (Soccer), sports first super app. The primary revenue model will be gambling focused on in-match play. A completely different model than the existing leaders, we are using the Stake.com blockchain strategy. Ecommerce similar to WeChat will also drive significant revenue. We intend to operate our own crypto marketplace, our own NFT marketplace, not to mention the mini program marketplace. Lots of good technology out there owned by startups that are out of cash and lack enough users to make it on their own. **OleOle** **Who We Are** **OleOle** is building a decentralized social network and messaging platform for global football fans — think Twitter + WhatsApp + TikTok + theScore + WeChat, built natively using **Rust**, WebAssembly, and blockchain-compatible architecture. Our mission is to disrupt the global sports ecosystem by empowering fans, clubs, and brands to connect, transact, and create — all without middlemen. From football content to commerce, ticketing, gaming, NFTs, and crypto betting — we’re building a super app for sports. This is a once-in-a-lifetime opportunity to be a founding engineer at a startup aiming to reshape how sports communities engage digitally — from the Champions League to the World Cup. **What we do...** oleolesport.com empowers people to identify football experience and without any search requirements, simply presents the traveler with vetted components necessary to bring the trip to life -- tickets, lodging, flights and beyond. And we are building a football super app. **Why we are better...** oleolesport.com’s searchless travel approach means a soccer/football experience can be discovered, planned and purchased in a matter of minutes without the endless search-driven lunacy and inefficiency that comes with all travel planning. There isn't a sports social network; some claim to be, however they lack even the slightest understanding of network platforms. ## Job Description **Job Title** **Founding Backend Architect / Principal Rust Engineer** **About the Role** OleOle is building a global, real-time social and messaging platform for sports fans — from the ground up, natively in Rust. This is not a feature role and not a task-driven role. We are looking for a senior backend engineer who has owned systems before and is comfortable making foundational architectural decisions that will not be rewritten later. You will design and evolve the backend architecture powering public conversations, real-time messaging, video, commerce, and token-based incentives for millions of users worldwide. **What You’ll Be Responsible For** - Designing and owning core backend architecture in Rust (async-first) - Defining service boundaries, data ownership, and evolution strategy - Designing scalable APIs (REST and/or GraphQL) for mobile and web clients - Modeling and operating PostgreSQL as a long-term source of truth - Architecting real-time systems (feeds, messaging, event-driven workflows) - Making tradeoffs around consistency, latency, and scalability - Working with DevOps while retaining backend architectural authority - Reviewing critical code paths and preventing premature complexity - Helping shape the backend team as the company grows This role is hands-on, but judgment matters more than output volume. **What You’ll Be Building** You will help lay the foundation for a native Rust platform that includes: - A large-scale social graph (users, clubs, countries, conversations) - Public feeds and real-time messaging - Video and media delivery pipelines - Token-based rewards and commerce - API infrastructure used across mobile, web, and internal services - Event-driven systems supporting live updates and notifications **Required Experience** - 7–12+ years of professional backend engineering experience - Proven ownership of backend systems in production - Strong, real-world Rust experience (async systems, not experiments) - Deep understanding of PostgreSQL data modeling and performance - Experience designing APIs and explaining tradeoffs clearly - Experience building or evolving systems that had to scale - Ability to reason about architecture without hiding behind buzzwords If you’ve never been responsible for a system’s long-term health, this is not the role. **Nice to Have (Not Required)** - Experience with real-time systems (feeds, messaging, streaming) - Experience with high-write or high-fanout workloads - ETL / data pipelines - Media or video delivery systems - Token, wallet, or crypto-adjacent systems (non-blockchain core) **Compensation & Stage** - Compensation is deferred until funding - Meaningful equity and long-term ownership - Founding-level responsibility and influence - Small team, high autonomy, minimal process This role is for engineers who want ownership, not safety. **What This Role Is NOT** - Not a ticket-driven implementation role - Not a DevOps-led backend role - Not a resume-padding opportunity - Not suitable for junior or mid-level engineers **Why This Version Works** - Senior engineers recognize themselves in this description - Resume fakers and ChatGPT engineers self-select out - You signal authority, ownership, and seriousness - You stop attracting people who “know the words” but not the work If you want, next we can: 1. Tighten this further into a LinkedIn job post 2. Create a one-paragraph screening message 3. Rewrite the technical challenge so fakers fail instantly ## Qualifications **Your Background** - 7-12 years of software engineering experience (preferably at early-stage startups or high-growth platforms) - 4+ years of experience working in Rust in production environments, ideally on scalable web or blockchain-native backends - Strong experience designing modern, scalable backend architectures from scratch — including authentication, real-time messaging, microservices, APIs, caching, and database design - Proficiency with Rust frameworks like Actix, Axum, Tokio, or Rocket - Experience with WebAssembly, gRPC, or GraphQL is a plus - Passion for decentralization, crypto, Web3, and building products that empower users - Comfortable working without product managers, defining scope, and leading engineering direction - Bonus: experience with blockchain integration, tokenomics, or building in no-fee marketplaces **OleOle – Where Fans Kick Off!**

## Company Description **About OleOle** OleOle is building the world’s first decentralized football super app — a unified platform that brings together social media, messaging, real-time scores, live video, gambling, e-commerce, and crypto rewards. We’re building something truly unprecedented — a next-generation **social network and messaging platform** designed exclusively for the world’s 3+ billion football fans. Think Twitter, WhatsApp, and TikTok fused into one global superapp — built natively using **Rust**, **Blockchain**, and **AI/ML**. Our vision is bold. We’re not just creating another app — we’re creating the **platform**. A decentralized, multilingual football community powered by real-time translation for Twitter->200 languages. But this isn't just social. We're monetizing through **crypto-native gambling**, building our own **NFT marketplace** focused on matchday imagery, and developing a **low-fee crypto exchange** we believe we can acquire and relaunch for almost nothing. With 4,000+ exchanges out there and fewer than 15 expected to survive, we see a clear consolidation opportunity. At the center of this entire ecosystem is our upcoming **crypto token, OleX** — a high-utility token powering transactions, rewards, gambling, and viral platform growth. We're looking for a **hands-on technical leader** to help architect this future, someone who knows Rust cold, understands blockchain inside and out, and has experience launching or scaling token-based platforms. Prior **ICO** experience is a big plus. This is not a CTO title in name only. You’ll be **leading from the front**, building the core architecture alongside a lean but growing team, helping us bring our decentralized football superapp to life. If you're looking to shape the future of social, crypto, and sport — this is it. ## Job Description If you don’t bother reading the job description please do not apply!
