Job Specifications

At Hadō, we are on a mission to restore trust in the digital world.

In an era of rampant misinformation and Generative AI, ensuring the authenticity and traceability of digital content has become a critical challenge for society. Hadō develops an invisible watermarking technology powered by deep learning that enables creators, brands, and industries to track their assets, prevent leaks, and verify the origin of content.

We are an early-stage startup, incubated at Agoranov (the home of Dataiku, Doctolib, Criteo) & WILCO, one of Europe's best startup accelerators. We are members of the C2PA standard body as well.

We are looking for a Full Stack Software Engineer Intern to join our team. You will work hand-in-hand with Bruno Spilak (CTO, PhD in Machine Learning) and collaborate with our existing engineering team to take our core technology and turn it into a world-class product.

Your Role & Responsibilities

You will join Hado to build and scale our product. Your main objective will be to take ownership of product blocks and features step-by-step. While you will be autonomous on your features, you will be supported by a dedicated tech team currently managing our robust infrastructure and core systems.

You will work closely with Bruno (CTO) on the following missions for example :

Feature Ownership & Development: Help develop new features "feature by feature." You will move from backend logic to frontend implementation as Web Apps, ensuring high-quality code and user experience.
Improve AI Search & Computer Vision Tools: Work on our advanced AI Search feature (reverse image search boosted by our invisible watermark), improving its efficiency and integration into the platform.
Help build the Hado Web Ecosystem: Develop and refine our Admin Panel and Customer Dashboards, allowing clients to manage their digital assets and monitor leaks in real-time, directly from their Web browser.
Collaborative Engineering: Work alongside our infrastructure and backend dev to ensure that the features you build are perfectly integrated with our existing high-performance systems.

Our Development Stack

Languages: Python (Proficient/Mandatory), TypeScript, JavaScript, SQL
Frameworks: FastAPI, Vite, NestJS
Infrastructure: AWS (EC2, Lambda, S3), PostgreSQL
Tools: Git

Who You Are

We are looking for a "builder"—someone who loves solving technical challenges and seeing their code directly impact the product and its users.

Education: You are in your final year of a Master’s degree or Engineering School (M2 / End-of-studies internship) with a specialization in Software Engineering.
Technical Proficiency: You have strong coding skills in Python. You are comfortable with backend architecture and have at least a basic/intermediate mastery of a modern Web framework like Vite.
Team Player: You are eager to learn from a senior team and contribute to a collective effort. English proficiency is mandatory.

What We Offer

Best Mentorship: Work directly with a PhD CTO and a structured tech team who will guide you through software engineering best practices.
Real Impact: You will be a key player in our product’s growth. Your code will directly help major brands in the Luxury and Corporate sectors protect their content.
Hiring Potential: We are looking for talent to stay! A full-time position (CDI) is the target outcome of this internship.
Top-Tier Ecosystem: Work from our office at Agoranov in Paris and be part of WILCO. You will be surrounded by the best French deep tech entrepreneurs.
A Cool & Ambitious Partnership: We work hard to build a world-class product, but we are also a fun-loving team that values true partnership and knows how to celebrate wins together.

The Interview Process

Intro Call with one of the founders to discuss the vision and fit (30 min).
Technical Interview with Bruno (CTO): Discussion on your previous dev projects, Python knowledge, and how you approach building a product block (1h).
Meet the Team: Lunch or coffee at Agoranov to ensure cultural fit.
