Full Stack Engineer for Applied AI Startup

We are hiring a Full Stack Engineer to a leading and category-defining AI startup in the public affairs space to help scale the core product as the company enters its next phase of growth, approaching 1M EUR ARR, and looking to scale ARR 5x in 2026.

This is a product-focused fullstack role with end-to-end ownership of features. You will build, evolve, and integrate user-facing functionality across frontend and backend, working closely with product, design, and commercial stakeholders. While parts of the product use LLMs, this role is primarily classic SaaS feature development.

What You’ll Do

• Build and ship fullstack features for the core product
• Own the end-to-end architecture and implementation of new feature development in our product
• Adapt the product for new geographic markets as the company expands
• Collaborate closely with product, design, and commercial teams
• Take responsibility for a defined domain within the product and help shape its roadmap
• Take charge of PoCs and solve complex, high-level technical challenges
• Our tech stack: TypeScript, Next.js, GCP and Kubernetes

What You Bring

• Strong fullstack engineering fundamentals
• Experience building and maintaining SaaS products
• Experience with TypeScript, Next.js, GCP and Kubernetes
• Product mindset and interest in understanding user problems
• Comfort with ownership, ambiguity, and responsibility
• Ability to collaborate with non-technical stakeholders
• Enjoyment of fast-paced startup environments
• You’re collaborative, humble, and focused on building what delivers the most value for customers

If you enjoy owning meaningful product areas and building software that supports important decision-making processes, we would love to hear from you.
