## 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.

Our mission is to provide institutional-grade, blockchain-enabled investment products and services. We have both a technology arm that develops decentralized finance technology, and an asset management arm that creates and manages tokenized funds. We were the first company to tokenize exposure to US Treasuries (and have since expanded into several other assets). We are also focused on incubating protocols that can support both tokenized real-world assets and traditional crypto. Founded by folks from Goldman Sachs’s Digital Assets Team, we’re backed by some of the best investors in the world including Founders Fund, Coinbase Ventures, Pantera Capital, Tiger Global, and more. We are currently the leaders in the space in terms of AUM and are well capitalized to continue to grow the firm. We're fully remote with team members across the US. ## About the role Ondo Finance is seeking a **Technical Support Engineer** to join our team at the intersection of product, engineering, and partner success. This is a hands-on, tactical role focused on supporting external integrations, troubleshooting issues, and freeing up core engineering time. You’ll work closely with Product, Engineering, and Business Development to support developers and partners integrating Ondo’s products and protocols. Initially, your focus will be reactive and tactical—resolving issues, answering integration questions, and improving documentation. Over time, you may take on more ownership of specific partners and integration workflows. This role is ideal for someone who wants deep exposure to real-world blockchain infrastructure, enjoys debugging and problem-solving, and thrives in a fast-paced startup environment. ## Key responsibilities - Serve as first-line technical support for external developers and partners integrating with Ondo’s onchain products and APIs. - Troubleshoot integration issues across smart contracts, SDKs, APIs, and infrastructure, escalating complex issues to core engineering when necessary. - Write light code (e.g., Python, JavaScript, Bash) to reproduce issues, build small utilities, test integrations, or assist with onboarding. - Improve and maintain technical documentation, FAQs, and example repositories to reduce recurring support burden. - Partner with Product and Engineering to identify common pain points and propose improvements to APIs, tooling, and DevX. - Help create repeatable internal processes and playbooks for handling support requests and partner onboarding. - Over time, develop ownership over specific partners or integration surfaces as trust and expertise grow. ## Requirements - 2 to 5 years of experience with strong fundamentals in software engineering or technical support. - Comfortable debugging APIs, reading smart contract interfaces, and working across backend systems. - Able to write and read code in at least one scripting or general-purpose language (e.g., Python, JavaScript, Go). - Clear communicator who can explain technical issues and resolutions concisely in writing and over video calls. - Highly organized and responsive—you take pride in closing loops and resolving issues quickly. - Interested in crypto, DeFi, and blockchain infrastructure; prior experience is a plus but not required. - Eager to learn, grow, and gradually take on more responsibility in partner-facing technical engagements. ## What we offer - Competitive compensation including salary, future token rights, and/or equity—designed to reward outstanding talent and contributions. - Full benefits (medical, vision, and dental) and a flexible vacation policy (PTO), recognizing work-life integration. - A small, remote-first team distributed globally—this is a chance to shape our culture and contribute at a pivotal moment in the company’s trajectory. - Work alongside A+ colleagues, including alumni from Goldman Sachs, Blackrock, Two Sigma, Bridgewater, SpaceX, AWS, Meta, Google, McKinsey, Circle, and Uniswap. - Backed by best-in-class investors, including Pantera Capital, Founders Fund, and Coinbase Ventures. --- **Req ID:** R50 *When applying, mention the word CANDYSHOP to show you read the job post completely.*
