Job description

Welcome to Nutrium

Before you apply, here's the key thing: our mission is to promote global well-being by making quality 1:1 nutrition accessible to everyone.

A lot has changed since we started, but our mission is still at the heart of everything we do — it's written in our culture book, in our proposals, in our docs, and it guides every decision we make.

It’s also what allowed us, for years, to improve the experience of nutrition professionals and their patients through the world's #1 nutrition counseling platform. But we didn't stop there.

Today, with Nutrium Care, we're taking the next step: bringing real, personalized nutrition to people anytime, anywhere, and helping them build healthier, happier lives.

Along the way, we raised our Series A and surpassed €15M in funding, partnered with global leaders like Vodafone, Adidas, Wellhub, and Linde, and reached millions of people around the world.

From day one, we also knew something else: building this future would take more than great tech. It would take a place where talented people can grow, feel supported, and actually enjoy the journey along the way.

You go first

We're proud of our journey so far, and we believe there's space for more people to shine, challenge us, and help shape what comes next.

What you will bring

You bring experience in AI and applying modern technologies like LLMs to solve real product challenges. You will take technical ownership of AI-driven features, collaborating closely with Product and Engineering in a fast-paced environment to shape solutions from discovery through delivery. You will build and take ownership of AI-powered features/solutions, making thoughtful technical decisions that improve workflows and decision‑making for dietitians and patients, with a tangible impact on a platform used by thousands.

What you will be doing

• Build and take ownership of AI-powered features designed to enhance Nutrium's platform.




• Apply Generative AI technologies, such as LLMs and RAG architectures, to address practical product challenges.




• Continuously monitor, troubleshoot, and fine‑tune AI solutions, ensuring a balance between key performance metrics and business requirements.




• Establish evaluation strategies and quality metrics (including groundedness, safety, latency, and cost) and work to continuously enhance them.




• Partner with Product, Engineering, and dietitians to transform requirements into robust, testable AI solutions.




• Create and maintain thorough documentation, lead technical discussions, and drive knowledge‑sharing initiatives to elevate team practices.

You might be a great fit if you...

• Have 1-3 years of experience building AI-powered solutions.




• Hold a degree in Computer Science, Software Engineering, Data Science, or equivalent practical experience.




• Build and code hands‑on solutions using LLMs in real‑world projects.




• Have specific experience with LLMs, RAG systems, and vector databases.




• Evaluate and improve AI systems through measurement and iteration.




• Are comfortable working with a high degree of autonomy, taking ownership of problems, and driving solutions.




• Are a strong problem‑solver who values collaboration, clear communication, and taking initiative.




• Demonstrate commitment to building with privacy and security in mind, including comfort working with sensitive data.




• Bonus: Are based in the north of Portugal (Braga/Porto);




• Are fluent in both Portuguese and English.
