At nao Labs, we are reimagining how data work gets done. Data work is different from traditional software development, and it deserves a specialised workflow. That’s why we’re creating nao—an AI-powered code editor tailored for data workers.

Software engineering Intern — Build the future of data teams experience.

Location: Paris 11, France

Hello, we're nao Labs

We are building an open-source AI agent for data analytics.

We are an early stage start-up with 2 cofounders - we joined Y Combinator Spring 2025 batch and STATION F and are now based in Paris 11.

We already have a first product - AI IDE for data people - used by 100+ data teams. We are now rolling out a new product - the open source analytics agent. So we’re looking for a founding engineer to help us build it!

We are a cofounding team with 18+ years experience in data/AI:

• Claire, our CEO, was Data Scientist at BCG Gamma, then head of data at sunday
• Christophe, our CTO, was staff Data Engineer at FreeNow, then worked as a freelance for Blablacar, Qonto. He then created his own blog and data community, blef.fr

nao is a fork of VS Code, which means NodeJS and Typescript.

We also use React for webviews. Python/Django and NodeJS for our backend APIs. A lot of LLMs to power our product.

The biggest challenges are:

• Navigating VS Code codebase to build a lovable product for data people
• Understand SQL and Python codebase to provide syntaxic trees
• Build low-latency AI Tab features and agentic workflows
