Full Stack Engineer

We are looking for a Full-Stack Developer to build the platform clients use every day. At Palau, we’re building the ontology layer behind a company’s digital twin - helping organizations connect their data, structure and sustainability knowledge so AI applications can work with real business context.

For clients including Lindt, Pioneer and Umicore, that means turning complex relationships into something useful and actionable. An energy figure belongs to a site, a reporting period and a source. A policy applies to specific activities and business units. A change in one dataset can affect several reports and decisions. Those connections need to exist in the product - and that’s the kind of complexity we enjoy solving.

We’re a small, international team of 8, of which 3 are on the dev team, working closely together with honest, open and efficient communication building in climate tech for the long term. The space has changed, priorities have shifted, and we’ve heard 'no' more than once - but we’ve kept building because we believe the problem is worth solving.

As a Full-Stack Developer, you’ll help shape both the foundation of the product and the applications people use on top of it. You’ll work closely with the team, have real ownership, and speak directly with the clients who use what you build. The work is challenging, thoughtful and rewarding - especially if you enjoy solving complex problems and want to see the impact of your work up close. This is a full-time, in-house position with flexible remote work in the Flemish region.

What you’ll do

• Build features end to end, from the interface to the API, together with our CTO and two engineers.
• Work on the data collection and consolidation pipeline, and on the tools that let our users build powerful, easy-to-manage reports.
• Take part in code reviews, testing and technical decisions.
• Suggest improvements to the product and the way we work.

In your first three months

• Ship your first features to production with support from the team.
• Get to know our data model and grow into the back end (Node.js, PostgreSQL).
• Take ownership of a part of the platform and share your ideas in planning and code reviews.

What we’re looking for

• 2+ years of hands-on experience with React and TypeScript in a product or client team.
• Curiosity: you want to understand how things work, not just that they work.
• Initiative: you spot problems and suggest solutions without being asked.
• Clear communication in English, and you enjoy explaining your thinking.
• You live in Flanders.

Our stack Next.js, React, TypeScript, Apollo, TanStack, Zod, Prisma, PostgreSQL (Neon), Auth0, Vercel AI SDK, Jest, Storybook, deployed on Vercel and AWS. You don’t need to know all of it; we’ll help you learn what’s new to you.

Nice to have

• Hands-on experience with some of the tools in our stack, especially Next.js, Prisma or PostgreSQL.
• Experience with data pipelines, data integration or reporting features.
• Interest in sustainability or ESG.

How we work

• Ownership. You take initiative and drive your work forward without waiting for instructions.
• Startup mentality. Things move fast, priorities shift, and you enjoy building something from the ground up.
• Open communication. You speak up, ask questions and share problems early.
• Quality. Every change goes through code review, and we care about code we can maintain.

What we offer

• A full-time, in-house employment contract.
• A gross monthly salary is between 3,500-4,800 EUR gross per month, depending on experience.
• Flexible remote work, with our office in Antwerp available and no strict office policy.
• Real ownership and a direct line to the founders in a small team.
• Meaningful work that helps companies meet their sustainability goals.
