Founding Platform Engineer

Job Description
Founded in 2026 by Robin and Maxime, Waniwani is backed by Hexa (eFounders), the pioneer startup studio in Europe.
Your job is to make Waniwani's infrastructure invisible at scale.
We launched the first insurance app inside ChatGPT. Now hundreds of companies want to deploy their own AI-native storefronts through our platform.
The Company
Waniwani is building the AI distribution infrastructure for the $10T services economy. We enable companies to sell quote-based services (insurance, wealth, …) directly inside LLMs, where buying decisions are moving.
This is Day 1 of a platform shift. Our ChatGPT insurance launch triggered $26B in market cap losses for the world's largest brokers in 48 hours.
Why This Role Exists
We're past proof of concept. The product works. Now we need to run it for hundreds of customers simultaneously.
This is a systems-level engineering problem. You'll own the architecture that lets Waniwani scale from dozens of deployments to thousands.
We expect 95% of your code to be written by AI. Your value isn't in typing. It's in knowing _what_ to build, _how_ to architect it, and _when_ the AI got it wrong.
What You'll Actually Do
Own the multi-tenant platform. Architect and maintain the infrastructure that hosts hundreds of MCP codebases.
Build the data backbone. Design the pipelines that aggregate statistics, analytics, and performance metrics across every deployed instance.
Ship the core app. Work hands-on in the main Waniwani application: a Next.js/TypeScript codebase with Drizzle ORM, React Query, and a modern component architecture.
Design for scale. Make architectural decisions that hold at 10x.
Automate everything. CI/CD pipelines, codebase provisioning, health monitoring, rollback systems.
Instrument relentlessly. Logging, tracing, alerting.
You'll work directly with the CTO. The architecture is yours to shape. The stack is TypeScript end-to-end.
This Role Is for You If
You've built and operated systems at real scale. You've dealt with multi-tenant architectures where tenant isolation actually matters.
You're a senior engineer with 5+ years of production TypeScript.
You think in systems, not features. When something works for one customer, you make it work for a thousand.
Native or bilingual English required. French is a plus.
Pluses
Experience with multi-tenant SaaS platforms
Built or operated big data pipelines
Deep PostgreSQL knowledge
Infrastructure-as-code experience (Terraform, Pulumi, or similar)
Familiarity with MCP (Model Context Protocol) or LLM tool-use ecosystems
Contributed to open-source infrastructure projects
Experience with Next.js, Drizzle ORM, or similar modern TypeScript stacks
Managed deployments across multiple cloud providers or edge networks
Built internal developer platforms or deployment automation
Why Waniwani
Ruthless execution.
Ownership. You'll architect the entire platform infrastructure from the ground up.
Category creation. You won't join a market. You'll contribute to defining a category.
Global. We sell global from day 0: US, Australia, Middle East, Korea… with offices in Paris, San Francisco, New York, and remote across Europe.
Real equity. Meaningful ownership at the earliest stage.
Best prep for founding. If you want to start your own VC-backed venture, this is the best battlefield to train on.
