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 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
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.

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:

  1. balanceOf(address): Returns the token balance of a specific address.
  2. transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
  3. approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
  4. allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
  5. User1 owns 500,000 ABC Tokens.
  6. User2 wants to buy 100 ABC Tokens from User1.
  7. User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
  8. User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
  9. The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
