Founding Platform Engineer at Waniwani | Paris

Waniwani

Full-time|On-site|Paris

Join Waniwani as a Founding Platform Engineer and revolutionize our infrastructure for seamless scalability.We have pioneered the first insurance application integrated with ChatGPT. Today, numerous companies are eager to leverage our platform to establish their own AI-driven storefronts. Each client requires a dedicated MCP server, a unique codebase, and tailored distribution, all functioning seamlessly and interconnected under your management.About WaniwaniWaniwani is at the forefront of creating the AI distribution framework for the $10 trillion services economy. Our platform empowers businesses to offer quote-based services such as insurance and wealth management directly within LLMs, where consumer purchasing decisions are increasingly shifting. Imagine Shopify, but tailored for services — we are constructing the foundation for AI-native commerce.We are just beginning this transformative journey. Our launch of ChatGPT insurance resulted in a staggering $26 billion in market cap losses for major brokers within just 48 hours, marking what the press has dubbed "the industry's ChatGPT moment." We refer to it as Day 1.Why This Position MattersHaving surpassed the proof of concept stage, our product is operational. We are now tasked with managing this for hundreds of clients simultaneously, each with its own MCP server, distinct data pipelines, and customized distribution dashboards, all while ensuring the platform remains robust and responsive.This role presents a systems-level engineering challenge. You will be responsible for architecting a solution that allows Waniwani to expand from dozens to thousands of deployments. This includes multi-tenant infrastructure, orchestration of multiple codebases, and real-time data flow across a multitude of interconnected services. In this role, a single flawed abstraction can cost months, whereas a well-designed one can save years.We anticipate that AI will write 95% of your code. Your expertise will not lie in typing code but in discerning what needs to be built, how to structure it, and when the AI may be misguided. You will work at a pace that integrates LLMs as a fundamental aspect of your engineering process, rather than viewing them as a novelty. The key challenge will be exercising judgment, not merely keystrokes.
