Joyride Labs
6 days ago
## 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.
FamilyCareCoop

## Technical Co-Founder — Family Care Cooperative **Boulder, CO | Full-Time, On-Site | Co-Founder Equity** ### The Short Version We're building the infrastructure for a new care economy — a worker-owned cooperative that replaces the extractive home care agency model with AI coordination, blockchain worker equity, and community care tokens. We need a technical co-founder who vibe codes prototypes at 10× speed and then architects production systems that real families depend on. **The tech:** React/Next.js, Solidity on Polygon, FHIR healthcare APIs, AI care coordination, and a federated SaaS platform designed to scale to 100,000 families. **The traction:** Boulder Community Health hospital partnership is in active discussion. $3.8M federal funding pipeline (CMS ACCESS + MAHA ELEVATE). Colorado tax credits are stacked. RMEOC cooperative formation underway. BVSD pilot channel identified (1,000 teacher families). ### The Problem We're Solving The $630B home care industry is structurally broken. Agencies extract 40-60% of every dollar as profit and overhead. Caregivers earn $15/hour with zero benefits and 77% annual turnover. Families pay $9,900/month for nursing facilities. 93 million Americans are caregivers with no infrastructure to support them. We're not fixing the existing model. We're replacing it. ### What You'll Build - **AI Care Coordination Engine** — Care matching algorithm (skills, proximity, personality, acuity). Predictive health monitoring (14-variable Care Readiness Index). Automated scheduling, billing, and EVV compliance with Colorado Medicaid. Natural language care plans and caregiver mobile tools. - **Web3 Worker Equity Infrastructure** — Smart contracts on Polygon for automated equity vesting (500 hours worked = full ownership share worth $52K over 5 years). ERC-20 Time Bank tokens for neighbor-to-neighbor care exchange. Self-sovereign identity (DIDs) for family health data ownership. - **Healthcare Data Platform** — FHIR-compliant API integration with hospital systems. HIPAA-compliant architecture. Real-time outcome tracking for CMS federal programs. Hospital discharge coordination dashboard. - **Federated Cooperative Platform** — "Hard Shell / Soft Center" architecture: national tech infrastructure, local care delivery. Multi-tenant SaaS licensable to cooperatives in every city. Employer HSA distribution integration. Community care marketplace. ### What We're Looking For **Must have:** - Ship MVPs in days using AI-assisted development (Claude, Cursor, v0, Replit) — you know what "vibe coding" means because you do it - Architect production systems that pass healthcare security audits — you know when to stop vibing and start engineering - Solidity smart contracts deployed to production (Polygon or Ethereum) - React/Next.js at a senior level — you've built and scaled real products - Comfort with ambiguity — you'll define the architecture, not inherit one - Boulder, CO-based or willing to relocate **Bonus points:** - Healthcare tech experience (FHIR, HL7, HIPAA compliance) - Cooperative or DAO governance design - Built token economies or DeFi protocols - Experience with CMS payment models or Medicaid billing - ML/AI pipeline development (not just prompting — model training) - You've built something that mattered to real people, not just raised money ### What You Get - **Co-founder equity** in FCC Technologies LLC. Significant stake. You own what you build. - **Compensation:** Competitive salary targeting Q3 2026 (hospital retainer + OEDIT grant funding). Sweat equity bridge until then. Open conversation about what works for your situation. - **Build from zero.** You're not inheriting legacy code. You're defining the architecture for a platform that will serve 100K families and create $52K in wealth for every caregiver who joins. - **A mission that actually matters.** Your code directly keeps aging parents at home for 1/3 the cost of facilities, creates real wealth for the lowest-paid essential workers in America, and builds community infrastructure through neighbor-to-neighbor care exchange. ### Your Co-Founder **Blaine Warkentine** — 15+ years in healthcare technology. Built BrainLAB's orthopedic vertical. Multiple healthcare M&A exits. Deep CMS/FHIR/regulatory knowledge. Currently running point on hospital partnerships, federal funding pipeline, state tax credit strategy, and cooperative formation. Needs someone who can turn the technical architecture into a production reality. ### How to Apply Send to **blaine@familycarecoop.com**: 1. Your GitHub (or equivalent portfolio) 2. One project you're proud of and why 3. Why building infrastructure for the care economy matters to you No cover letter. No resume formatting games. Just show us what you've built and tell us why you care. *Family Care Cooperative — Boulder, CO — Worker-Owned. Zero Extraction. Building the last defensible human economy.* When applying, mention the word CANDYSHOP to show you read the job post completely.

## Company Description This is not a traditional engineering role. We are seeking a completed or near-complete blockchain-based sports betting platform, or a founder/CTO-led team that has already built and launched a real-money product. The platform may have stalled due to funding, licensing, distribution, or marketing challenges. That is acceptable. We are interested in experience and execution, not résumé credentials. If you have not personally built, launched, or operated a real-money sports betting or gambling platform, this role is not a fit. **OleOle** OleOle is building a social network and messaging platform for football/soccer. In-match gambling driven by live score updates is the driver of our model. **What we do...** OleOle is building a **blockchain-based sports betting platform** as part of a larger football-focused ecosystem with built-in distribution, licensing strategy, and capital support. We are looking to connect with **technical founders or senior engineers who have already built a crypto-native or blockchain-enabled sports betting platform**—one that is live, previously live, or production-ready—but **failed to scale due to funding, customer acquisition, or licensing constraints**, not technology. This is **not a greenfield build** and **not a standard engineering role**. We are specifically seeking people who have **real, working blockchain betting infrastructure** and are open to folding that technology and expertise into a larger, well-capitalized organization. ## Job Description This role is ideal if you have: * Built or operated a **blockchain or crypto-based sportsbook** * Hands-on experience with: * On-chain or hybrid (on-chain / off-chain) betting architecture * Smart contracts for wagers, settlement, or escrow * Odds feeds and oracle integrations * Risk management and exposure controls * Crypto wallets, custody, and transaction flows * User accounts, KYC, AML, and compliance-adjacent systems * A platform that: * Reached live users, beta, or production readiness * Struggled due to lack of capital, liquidity, or distribution—not engineering * Interest in **integrating into a larger platform** rather than rebuilding alone We are open to **solo founders, lead engineers, or small technical teams**. ### What This Role Is (and Is Not) **This is:** * A chance to bring **existing blockchain betting technology** into a broader ecosystem * A role focused on **integration, scaling, and hardening** production systems * An opportunity to work with a company that will handle **marketing, licensing, and growth** **This is not:** * A greenfield smart contract project * A typical Web3 “dev role” * A consulting engagement * A pitch deck–only conversation without real code ## Qualifications **Technology Focus** We are particularly interested in experience with: * Crypto-only betting flows * Smart contract–based settlement * Oracle-driven odds and event resolution * Hybrid architectures that balance on-chain trust with off-chain performance * Secure wallet integration and transaction lifecycle management **Structure & Upside** Engagement structure will vary based on what exists today and may include: * Technical leadership role * Equity or revenue participation * Technology acquisition or licensing * Long-term role inside OleOle’s in-house gambling operation The goal is alignment and long-term ownership—not short-term contracting. ## Additional Information We value solutions, not problems. * Creative problem solver who can courageously propose and support new ideas to our organization. Not interested in best practices; let's build something better! * Ability to adapt. An ideal candidate will welcome the opportunity to solve a broad range of problems using a wide array of technologies. * Comfortable with ambiguity, shifting priorities and general growing pains of an early-stage technology company. * An exceptional entrepreneurial judgment that fosters independence over micro-management. * Understanding of football and international sports a huge plus. OleOle is located in beautiful Austin, Texas; however, this role requires some travel. We are privately held and rapidly growing! *When applying, mention the word CANDYSHOP to show you read the job post completely.*
