Product Engineer Backend (w/m/d)

Berlin or Hamburg | Hybrid | Salary: €70,000–80,000

If you're excited about building scalable backend systems, taking ownership beyond your code, and helping shape a modern engineering culture from the ground up, this is your opportunity.

We're building the next generation of a B2B2C MarTech platform inside a corporate-backed startup environment. A true greenfield product with millions of existing users and the freedom to rethink how product engineering should work.

You'll join a Product & Tech organization that is evolving from a traditional delivery model into a modern, cross-functional, product-led engineering culture.

Your Mission

You build backend services that don't just work; they create measurable product value.

You take ownership of features from the initial idea through implementation, testing, deployment, and continuous improvement.

You understand how your services interact with the wider platform and make technical decisions with the overall system in mind, not only your own code.

You work closely with Product, Design and Frontend Engineering to build scalable solutions that balance customer value, engineering quality and delivery speed.

You proactively identify opportunities for improvement, challenge technical decisions where appropriate and contribute to a culture of ownership, transparency and continuous learning.

You use AI engineering tools thoughtfully to accelerate learning, debugging, and problem-solving while always validating your own decisions.

This role is for you if...

• you have several years of experience building backend applications in Java, ideally with Kotlin.
• you enjoy understanding complex distributed systems instead of focusing on isolated services.
• you naturally think beyond implementation and care about product outcomes.
• you take ownership from discovery to production.
• you enjoy solving complex technical problems in a pragmatic way.
• you are comfortable balancing MVP thinking with long-term maintainability.
• you thrive in product companies where engineering quality has direct business impact.
• you are looking for an environment where autonomy, transparency, and accountability matter.

What you'll work with

• Java / Kotlin
• Spring Boot
• Modern Backend Architecture
• Distributed Systems
• AI-assisted Software Engineering
• Product-led Engineering
