Certo careers

Certo is an AI-native B2B SaaS company on a mission to make product compliance automatic, reliable and fast for the global consumer goods industry.

Today, launching a new cosmetic, personal care product or medical-adjacent device means navigating a maze of regulations, supplier PDFs, spreadsheets and consultants. Every country, retailer and regulator has its own rules. Every new ingredient, market or claim triggers weeks of manual checks and email threads.

Our value proposition is simple: product compliance automated at scale, unlocking new revenues for the consumer goods industry. We turn regulations, supplier documents and formulas into structured data and rules, run automated compliance checks across markets, ingredients, formulas, labels and dossiers, and generate audit-ready evidence for every decision with citations and clear reasoning.

We work with regulatory, QA and R&D teams to help them decide faster where they can launch, de-risk complex formula and supplier choices, and replace manual document review with AI-driven, but fully explainable, workflows.

We are very early: a tiny team in Paris, live pilots with leading European beauty and personal care companies, and a huge amount of greenfield product to build. We are backed by early-stage investors and operate at the intersection of B2B SaaS, developer-style thinking ("compliance as code"), and agentic AI designed for regulated environments.

Culture-wise, we optimise for ownership, clarity, curiosity and low ego. As a founding engineer here, you will own meaningful chunks of the product and architecture, talk directly to users, and help turn a messy, high-impact problem into clean, robust systems that move an entire industry forward.
