The Role
☀️ We are Dazle

Dazle was founded by Emmanuelle (CEO) & Theo (CTO), two entrepreneurs passionate about cybersecurity. We aim to build the future of AI-powered application security. Traditional vulnerability scanners drown engineers in false positives, we cut through the noise with context-aware exploitability analysis, helping teams focus on real threats.

As a founding engineer you will take a crucial part of building the whole product and the underlying tech, hand-in-hand with the CTO. In such an early-stage, fast-paced environment, you are expected to write code for every part of the product. Mostly focused on backend and AI-related work, you will also have the opportunity to built our awesome frontend.

🚀 We are backed by Hexa (eFounders)

Hexa partner with talented cofounders to build the future of product-led SaaS.
Hexa pioneered the startup studio model in 2011 and have since launched over 40 companies (7 of them have made exits) with $700M in funding and now reaching a valuation of over $5 billion - including Front, Aircall and Spendesk which recently became unicorns.

Today, over 2,500 employees across the world work in a startup which started out as a simple mockup right here at eFounders.
