Full Stack Engineer

Full Stack Engineer | SaaS Software Start-Up

Are you a curious full stack engineer who loves clean code, meaningful problems, and wants to work on AI applications with real impact?

At Passionfruit, you'll join a fast-growing startup with a small development team where you can shape the product, improve the architecture, ship meaningful features, and help transform how the food industry handles sustainability, safety, and compliance.

We've laid the foundation. Now we're looking for someone like you to take it to the next level.

Who We Are

Passionfruit is the intelligent automation platform transforming how sustainability, safety, and compliance teams in the food industry work.

By combining Gen AI with intuitive workflows, we automate tasks like answering customer questionnaires and preparing for audits, all within the tools teams already use: Excel, Word, and online portals. We integrate seamlessly into their day-to-day grind, and with every interaction, Passionfruit grows smarter. We're building a trusted, traceable knowledge layer teams can rely on. The result? Teams work 3x faster, respond more confidently, and get back to what really matters: making an impact.

Headquartered in Rotterdam, our team values curiosity above all. With VC backing, and growing customer base every month, we're expanding quickly and need innovative engineers like you to make a significant impact.

Your Role

As our full stack engineer, you'll be at the core of our product development and part of a small, talented development team. You'll work across the stack to ship user-facing features, integrate new AI capabilities, and improve the performance, scalability, and maintainability of our platform. You'll be at the forefront of building a vertical AI SaaS product and applying cutting-edge models to industry-specific problems with real impact.

What You'll Do:

• Build end-to-end features in React/Next.js (frontend) and Node.js/Python (backend)
• Develop and scale: API's and data workflows, hosted on Azure/AWS
• Product Strategy Influence: Collaborate directly with the founders to guide our engineering strategy.
• Own the architecture: Make infrastructure decisions, and dev practices that scale with the product.
• Think critically: about how to deliver value today while building towards a robust system tomorrow
• Shape how we grow: Your ideas and energy will help build the team and culture from the ground up.

Ideally, you have 3+ years of experience working with the following technologies:

• Back-end: Node.js, Python
