About Dashlane

Dashlane’s mission is to deliver the credential security every business and employee needs to thrive. Millions of consumers, and over 25,000 brands worldwide, such as Michelin, Air France, and Forrester, trust Dashlane for industry-leading innovations, patented zero‑knowledge security, and an unmatched user experience. Founded in Paris, Dashlane has since established offices in New York and Lisbon, and has grown to more than 300 Dashlaners globally.

Role

You'll work on cutting‑edge research in web understanding, using large labelled and unlabelled datasets of web pages. As a member of the ACE team, you'll help pioneer a state‑of‑the‑art web analysis that will make life easier and more secure for millions of people worldwide. The team’s mission is to enhance user security and core product features through intelligent, AI‑powered capabilities, such as improving the autofill experience, detecting credential risks, and protecting against phishing attacks. The team comprises Software Engineers and Machine Learning Engineers to ensure the quality of our analysis.

We leverage advanced Machine Learning techniques to build intelligent security tools within a zero‑knowledge architecture. Our blog post demonstrates how we implement autofill capabilities without accessing user data. We also explain our privacy‑preserving approach to real‑time threat detection and phishing prevention. We advocate for public specifications for field autofill, such as Semantically Annotated Web Forms.

Location

You will be based in Paris, with a hybrid policy (three office days per week) and English as your working language. Our model is designed to strengthen team connections while supporting individual productivity and work‑life balance. We come together in the office on Mondays, Tuesdays, and Thursdays, while Wednesdays and Fridays offer more flexibility for focused work.
