Full-Stack Developer

About the Role

Join the core engineering team of an early-stage AI startup as a Full-Stack Developer, building scalable web applications that power an AI-driven product. You'll work closely with product, design, and fellow engineers to ship features end-to-end — from initial concept through to customers — in a high-impact environment where your contributions directly shape the platform.

What You'll Do

• Design, develop, and maintain scalable web applications across the full stack.

• Collaborate with product managers, designers, and engineers to bring new features to life.

• Write clean, maintainable, and well-tested code with a focus on quality and longevity.

• Participate actively in code reviews, giving and receiving constructive feedback.

• Troubleshoot and debug production issues, identifying root causes and implementing effective solutions.

• Contribute to architectural decisions and help shape the technology roadmap, particularly around AI capabilities.

What We're Looking For

• 3+ years of professional experience as a Full-Stack Engineer or in a similar role building and shipping web applications.

• Proficiency in at least one modern programming language (e.g. Python, JavaScript, TypeScript, Java, or Go).

• Experience with a modern frontend framework such as Vue.js, React, Angular, or Svelte.

• Experience with a backend language or framework such as Python, Node.js, Java, Go, or C#.

• Strong grasp of software engineering principles, design patterns, and architectural decision-making.

• Demonstrated ability to write clean, tested code and engage meaningfully in code reviews.

• Experience troubleshooting and debugging issues in production systems.

• Collaborative mindset with excellent communication skills.

• Interest in or experience with AI-related technologies or machine learning frameworks is a plus.

• Familiarity with cloud platforms (AWS, GCP, or Azure) is a plus.

• Open-source contributions or a personal project portfolio are a plus.

• Willingness to relocate to Berlin, Germany — visa sponsorship is not available.
