Full-Stack Software Engineer

Department: Engineering

Location: Berlin

Employment Type: FullTime

About the Role

This is a full-stack engineering role at an early-stage enterprise AI SaaS startup, where you'll have meaningful ownership over features from conception through production. You'll work across the full stack — backend APIs, database layers, and frontend — helping shape both the product and the technical architecture of a platform used for company-wide AI adoption.

What You'll Do

• Design and implement robust backend systems and APIs to power an enterprise AI platform.

• Build end-to-end solutions spanning backend (Node.js), database layers, and frontend integration.

• Develop and optimize database schemas, queries, and data models for performance and scalability.

• Implement API endpoints and integrate with third-party services and AI providers.

• Collaborate on technical architecture decisions and system design across the engineering team.

• Maintain and optimize the codebase for performance, reliability, and maintainability.

• Participate in support engineer rotations, shifting focus periodically to assist customers and the customer support team.

What We're Looking For

• 3+ years of full-stack web development experience.

• Strong proficiency in Node.js, React/Next.js, and TypeScript.

• Solid experience with PostgreSQL and SQL — data modeling, querying, and optimization.

• Comfort using Tailwind CSS for frontend styling and implementation.

• Track record of owning features end-to-end in production environments.

• Experience building AI-powered features or integrating AI/ML services into applications.

• Strong CS fundamentals and system design sensibility.

• Clear communication and collaboration skills with product and cross-functional stakeholders.

• Willingness to participate in regular customer-facing support rotations.
