At Gemmo AI, we build custom AI solutions that combine automation with human insight. We use a modular approach: first we explore the highest-impact opportunities, then we design and deploy tailored solutions, and finally we help improve and maintain them over time.

About the Role

We are looking for a junior fullstack developer with experience in Machine Learning to join our team and help integrate our models and solutions into our clients’ cloud infrastructures.

You will be responsible for co-designing, building and maintaining CRUD APIs, creating the UI, launching and orchestrating Machine Learning inference pipelines, and deploying the solution on the cloud.

You will collaborate closely with UI/UX designers and Machine Learning engineers ensuring that AI components integrate into end-to-end solutions.

Beyond implementation, you will play an active role in shaping and refining our pipelines, maintaining scalability, reliability, and performance as we continue to innovate.

Compensation

• Full-time contract (tempo indeterminato);
• Up to 28k€ RAL, depending on experience;
