Software/AI Engineering - Freelance

Waniwani is building the Shopify of AI commerce. We empower companies in Financial Services and SaaS to deploy MCP-powered solutions that live natively inside LLMs : where buying decisions are already being made.

We launched the first worldwide insurance app inside ChatGPT and wiped out 28B$ of market capitalisation. Now the market noticed. This is Day 0 of AI-native distribution, and we're moving fast.

We are looking for an AI/LLM developer to build production-ready MCP-powered applications for our clients, on a project-by-project basis, starting immediately.

You will be working at the frontier of AI distribution, not building chatbots, but deploying the infrastructure that lets companies sell, communicate, and transact natively inside LLMs.
