This is an Atlantic Labs portfolio venture. Find out more about us and other opportunities in our portfolio here.

About the Venture

We are a Paris-based, pre-seed startup reimagining how visual content is created in the age of AI. Our vision is to democratise high-quality visual storytelling by removing technical and resource bottlenecks. With deep expertise in generative models, we’re building an intelligent design platform where anyone in a company- not just designers - can instantly create stunning, on-brand visuals. We’re backed by leading VCs and top operators in marketing and AI, and already work with well-known customers across Europe.

We believe the future of visual marketing lies in decentralised, AI-powered creation - where marketers can rely on autonomous agents tailored to their brand and needs. We're building toward that future now.

About the Role

We're looking for a Full-Stack Engineer to join our small, fast-moving team and help us build the next generation of AI-augmented content creation tools. This isn’t a traditional engineering role - you’ll have ownership from day one and work on everything from integrating the latest AI models to building interactive workflows for visual generation and editing.

You’ll collaborate closely with founders, designers, and fellow engineers to ship end-to-end features with high impact. Our current stack includes Python, TypeScript, FastAPI, React, AWS, and Docker, and we regularly experiment with state-of-the-art models and agents.

What you’ll do:

• Design and build user-facing workflows powered by generative AI.

• Develop backend infrastructure to support scalable, production-ready AI features.

• Work with image and video generation tools and build seamless, intuitive user experiences.

• Integrate external APIs and tools to expand our product capabilities.

• Move fast, test ideas quickly, and help shape our product roadmap.

About You

You’re a creative and pragmatic engineer who loves shipping things that work. You enjoy working across the stack, experimenting with new technologies, and turning early-stage ideas into polished features. You’re not afraid to take shortcuts when needed - but you know when to build for scale.

What you bring:

• Strong backend experience, ideally with Python and FastAPI (or similar frameworks).

• Frontend proficiency in modern frameworks like React.

• Experience working with cloud infrastructure (AWS, Docker, etc.).

• Curiosity about AI and eagerness to dive into generative model integration.

• A builder mindset - you like to test, iterate, and get features in front of users quickly.

• Bonus: experience working on early-stage products or startups.

Why Join

• A front-row seat in an emerging AI category with global potential.

• Immediate ownership and impact - ship things weekly and see them in users’ hands.

• Deep exposure to real-world AI applications and design tooling.

• Competitive salary and equity (BSPCE) - we want you to share in our success.

• Offices in central Paris (near Saint-Lazare) + remote-friendly setup.

• A humble, ambitious team that values curiosity, simplicity, and transparency.
