Description du poste

️We are DetectX

DetectX 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 in 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 build our awesome frontend.

We are backed by Hexa (eFounders)

Hexa partners with talented cofounders to build the future of product-led SaaS.

Hexa pioneered the startup studio model in 2011 and has 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 that started out as a simple mockup right here at eFounders.

Companies: Roundtable • Elba • Dotfile • Swan • Cycle • Folk • Upflow • Yousign + many other startups and more to come.

Your mission

• Build robust backend systems for large-scale code analysis.
• Contribute across the stack (some frontend work in React/Typescript).
• Mentor future engineers as the team grows.

Is that you?

• 2+ years in backend engineering, with Python experience (FastAPI).
• 3+ years in AI/ML engineering having deployed pipelines and/or models in production.

Bonus points if you have:

• Exposure to security world (SAST, DAST, reverse engineering).
• Experience with React / Typescript.
• Startup-friendly: You thrive in ambiguity, move fast, and own outcomes.
• Security mindset with strong collaboration skills. You communicate effectively with anyone and are deeply motivated by DetectX's mission.
