## 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.

## The World of Digital Assets The world of digital assets is accelerating in speed, magnitude, and complexity, opening the door to new ways for leveraging the blockchain. **Fireblocks’** platform and network provide the simplest and most secure way for companies to work with digital assets and it is trusted by some of the largest financial institutions, banks, globally-recognized brands, and Web3 companies in the world, including BNY Mellon, BNP Paribas, ANZ Bank, Revolut, and thousands more. The world of digital assets is accelerating into mainstream finance and reshaping how money moves, how assets are owned, and how new products are built. Fireblocks sits at the center of this transformation, offering institutional-grade security and infrastructure for organizations across the digital asset ecosystem. Fireblocks is relied on by the world’s leading financial institutions, banks, fintechs, and crypto companies, including BNY Mellon, Robinhood, Revolut, and thousands more. As part of Fireblocks, **Dynamic** represents the next evolution of non-custodial wallet infrastructure. Dynamic is Fireblocks’ embedded wallet platform, purpose-built for developers who want to bring crypto and stablecoin experiences into modern applications without complexity. Together, Fireblocks and Dynamic are building the most complete, secure, and developer-friendly wallet infrastructure in the industry by combining institutional-grade security with consumer-grade experiences. ### About The Team Dynamic was founded in 2021 with a simple vision: every app and website will have a wallet component. That vision is rapidly becoming reality. Wallets are no longer limited to crypto-native products, they are becoming foundational infrastructure for payroll, remittances, and global payments. Dynamic powers wallet-based experiences for leading crypto and fintech teams including Kraken, Zerohash, Magic Eden, and more. Dynamic builds and maintains developer-first SDKs that enable teams to seamlessly integrate embedded wallet functionality directly into their applications. These embedded wallets allow end users to create, manage, and use wallets without leaving the product experience, making wallets feel like a native part of modern fintech and crypto apps. As part of Fireblocks, the Dynamic team continues to build and scale the infrastructure and developer tooling that has onboarded 50M+ wallets across crypto and fintech applications. In this context, Dynamic powers the application-layer wallet experience and developer tooling, complementing Fireblocks’ core custody, security, and transaction infrastructure. The team operates with a strong product mindset and deep focus on security, reliability, scalability, and exceptional developer experience. Engineers at Dynamic build secure-by-default systems and approach their work with a strong customer focus, balancing technical excellence with real-world user needs. You will be joining a passionate group that moves fast, works with the biggest names in payments and fintech, and is defining how the next generation of financial applications are built. ### What You’ll Do - Design and implement rich frontend experiences and scalable backend services that power Fireblocks’ wallet infrastructure through the Dynamic platform - Own features across the stack: from technical design and architecture through implementation, testing, deployment, and ongoing optimization - Build and maintain backend services and APIs supporting authentication, wallets, and payments infrastructure - Develop user-facing features and frontend tooling for both end-user and developer-facing applications - Collaborate closely with Product, Design, and other engineering teams to deliver robust, high-impact features - Contribute to performance, reliability, and scalability improvements across the platform - Help uphold engineering best practices through code reviews, testing, documentation, and knowledge sharing ### What You’ll Bring - 3–5 years of experience building and shipping production-grade, full-stack web applications - Strong experience with React and TypeScript on the frontend - Experience building backend systems and APIs using Node.js (and frameworks such as Express) - Comfort working across frontend and backend systems in complex, evolving codebases - A strong appreciation for clean, maintainable code and system performance - Experience collaborating cross-functionally with product and design partners - Curiosity about fintech and Web3, and interest in building infrastructure used at global scale ### Big Advantages - Experience with blockchain technologies (e.g., EVM chains, wallets, on-chain integrations) - Solidity experience – writing, deploying, testing, or interacting with smart contracts in production environments - Experience maintaining, testing, and securing smart contract systems post-deployment - Experience with a variety of state management solutions in production React applications - Experience with security products or other high-sensitivity domains ### Compensation & Benefits For employees hired to work from our NYC HQ, Fireblocks is required by law to include a reasonable estimate of the compensation range for this role. This range is specific to New York City, and takes into consideration a wide range of factors that are reviewed when making a hiring decision, such as years of experience, skills, and other business needs. It is not typical for a candidate to be hired at or near the top of the pay range and each compensation decision is dependent on each individual case. A reasonable base salary range estimate for this position is **$177,000 to $230,000**. The base salary is one component of the total compensation package, which for some roles may include a target bonus, a very competitive equity grant, and very generous benefits. While we believe competitive compensation is a critical aspect of you deciding to join us, we do hope you also spend time considering why our mission and culture are right for you. We are creating something transformational here, and we hope you are as excited about the future as we are. *Fireblocks' mission is to enable every business to easily and securely access digital assets and cryptocurrencies. In order to do that, we strongly believe our workforce should be as diverse as our clients, and this is why we embrace diversity and inclusion in all its forms.* *Please see our candidate privacy policy [here](here).* **When applying, mention the word CANDYSHOP to show you read the job post completely.**
