Founding Full Stack Engineer

Clave is building an AI-native operating system for QSR franchises, connecting POS, inventory, labor, ERP, and more into one AI brain that analyzes data, recommends actions, and executes across locations. As a Founding Full Stack Engineer in Miami, you’ll build production AI agents, data pipelines, and full-stack features end-to-end—shipping fast, handling messy real-world data, and owning infrastructure. This is an in-office, high-agency role for a mission-driven builder who thrives in ambiguity and wants meaningful equity.

We're not just building another SaaS product. We've lived the problem:

Our family runs ChurroMania (140+ stores, 10 countries, $34M revenue). We've watched Burger King struggle with 1996 Panasonic software. We've seen McDonald's run Windows XP systems from 2005. We know exactly what it's like to operate based off of gut instinct instead of data, and have to think about a million things while trying to run your store at the same time.

The future is autonomous stores run by AI. We're building it from lived experience, not a hunch.

Why We Win

1. Domain Expertise: 20+ years operating QSR franchises at scale

2. Real Customer Problems: We're our own first customer (ChurroMania as testing sandbox)

3. Traction: $103K ARR in 5 months, 36% MoM growth, customers including Jamba Juice, Oakberry, Auntie Anne's

4. Funded & Growing: Raising $750K pre-seed, already have commitments from Geek VC, Hustle Fund, Untapped Capital

5. Second-Time Founders: We've built and exited before. We know how to ship.

6. Link to something you built (GitHub, deployed project, demo video)
