YC-backed nao Labs is hiring a founding software engineer to develop its open-source analytics agent, following traction with its AI IDE used by 100+ data teams.
Paris-based nao Labs, part of Y Combinator's Spring 2025 cohort and STATION F incubator, is expanding its technical team to accelerate development of its open-source AI agent for data analytics. The startup, founded by Claire Gouze (ex-BCG Gamma, sunday) and Christophe Blefari (ex-FreeNow, BlaBlaCar), has secured early traction with its existing AI-powered IDE product used by over 100 data teams. Now they're recruiting a founding software engineer to build their next offering: an agentic system designed to transform how data professionals work.
Unlike generic AI tools, nao Labs focuses specifically on data workflows—a domain cofounder Gouze describes as fundamentally different from traditional software development. Their approach centers on creating specialized interfaces that streamline data exploration, transformation, and analysis. The new agent aims to automate complex data tasks through conversational interfaces while maintaining the precision required for analytical work.
The founding engineer role requires full-stack proficiency with React, TypeScript, Node.js, and Python, plus hands-on experience building agentic systems using platforms like Vercel and LLMs from OpenAI or Anthropic. Beyond technical execution, the hire will influence product strategy by translating user feedback into features and helping shape the company's technical direction. Compensation includes €45K–€80K salary and 1–3% equity, with hybrid work options from their Paris office.
nao Labs exemplifies the growing trend of vertical AI tools targeting specific professional workflows. Their dual focus—combining an established IDE with emerging agent technology—positions them to capture more of the data team workflow lifecycle. As data complexity increases, solutions that reduce friction in exploratory analysis could significantly accelerate insights across industries from finance to logistics.
For engineers interested in agent architecture or open-source data tools, this role offers rare early-stage influence: The successful candidate will be the third technical member joining a team of four, working directly with founders on core systems. Applications remain open through Y Combinator's job board.
