Boulder, CO | Full-Time, On-Site | Co-Founder Equity
The short versionWe'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 solvingThe $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 buildAI 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 forMust 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
- 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
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-founderBlaine 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.

What is ERC20 example?
ERC20 is a standard for fungible tokens on the Ethereum blockchain
Here is an example of an ERC20 token
Let's say we create a new ERC20 token called ABC Token with a total supply of 1,000,000 tokens
Each token will be divisible up to 18 decimal places
To implement the ERC20 standard, we will need to define several functions, including:
- balanceOf(address): Returns the token balance of a specific address.
- transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
- approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
- allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
- User1 owns 500,000 ABC Tokens.
- User2 wants to buy 100 ABC Tokens from User1.
- User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
- User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
- The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
