Front end developer Jobs in Heidelberg

Transform the future of the built environment through purpose-driven technology.

Enzo builds software that connects IoT devices, AI systems, insurers, and property owners into one coherent platform. Our applications turn raw sensor data into actionable insights, and reliability, clarity, and performance matter.

As Full Stack Developer, you’ll build and evolve our web and app experiences using a TypeScript-first stack. You’ll work closely with backend, AI, and product teams to ship features fast, without sacrificing code quality.

Tasks

Role Overview

You’ll contribute across the stack, with a strong focus on TypeScript, modern frontend architecture, and clean system interfaces. While we also use React Native for our app, the primary focus is TypeScript-based development, not mobile specialization.

This is a hands-on builder role in a fast-moving startup environment.

• Translate product requirements into pragmatic technical solutions.
• Actively contribute to technical discussions and decisions

• Support cloud-related tasks when needed (CI/CD, deployments, monitoring).
• Help improve system reliability and developer experience.

Requirements

Strong TypeScript Engineer

• Strong React fundamentals.

Pragmatic Full Stack Mindset
