## 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.

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.
