Job description

We welcome applicants with a range of experience levels, from those a few years into their career to seasoned engineers. If you are just starting your career but already have experience working alongside your studies, we are also happy to talk to you.

We’re looking for a Product Engineer with a strong backend specialization, a solid technical foundation, and experience working on SaaS products in Agile environments. You’ll help us build reliable, scalable product experiences, with deep ownership of backend systems while staying close to the full user journey.

This role is for someone who is willing to extend their impact across the full stack, from APIs, data models, and infrastructure to the product’s user experience, using AI to bridge the gap where needed. You’ll work closely with product, design, and engineering to turn ideas into high-quality shipped features.

What you can expect

• Cross-functional Collaboration: You will join a product squad and work closely with designers, product managers, and experienced engineers across backend, frontend, mobile, and AI.

• Shift in Software Engineering: Driven by AI, the role is moving toward end-to-end ownership—focusing on understanding user problems, shaping product decisions, rapid prototyping, and validating ideas, rather than just coding from strict specs.

• A Shared Transition: The company is undergoing this transformation itself; you aren't expected to have everything figured out from day one.

• Key Traits Valued: What matters most is your curiosity, adaptability, strong engineering judgment, and a genuine willingness to learn new ways of working.

• Growth and Support: You will receive the tools, practices, and team environment needed to evolve into a product-minded, AI-enabled engineer while continuing to deepen your technical expertise.

What you bring to the table

If you're excited about the role but don't tick every box, we still want to hear from you. Your attitude and willingness to learn matter more to us than matching every bullet.

• Backend Proficiency: Hands-on experience with Kotlin (or Java) and a web framework like Micronaut or Spring, ideally in a SaaS environment.

• Cross-stack Mindset: Backend is your home stack, and you're willing to step into web or mobile when a feature calls for it.

• Comfortable with AI Coding Tools: You use AI coding assistants (Cursor, Claude Code, Copilot, etc.) as part of your workflow, or are eager to adopt them, to navigate unfamiliar codebases, bridge the gap to frontend, mobile, or infrastructure, and ship small, well-structured changes outside your home stack.

• Ownership: You think in terms of user impact, not tickets. You ask "what would actually help the user — or what would bring me closer to understanding that?" and see it through: a prototype, instrumentation on existing features, a conversation with a PM or Customer Success - whatever the question calls for. You carry features through to rollout and observe their impact.

Nice to Haves:

• Experience pairing with designers or working directly from mockups/prototypes.

• Instrumentation and experimentation experience (A/B testing, Grafana, Mixpanel, etc.).

• Deployment with Kubernetes and Helm

• Experience with PostgreSQL.

• Experience with messaging systems (RabbitMQ, Apache Kafka).

What we offer you

• Work mode: We’re remote-first, giving you flexibility to work from home. At the same time, we deeply value the power of in-person collaboration. Depending on the role, you’ll join occasional team events, workshops, or meetings in our Berlin or Stuttgart offices - always with plenty of notice. The exact balance will be discussed during your interview.

• Work-Life-Balance: We don't want you to grow roots to your desk chair. That's why we cover the costs of your E-Gym-Wellpass membership and offer job bike leasing.

• Celebrating success: Expect highly motivated and committed people in a relaxed working atmosphere.

• Be part of something bigger: You actively shape Flip in your role. Along the way, you are an enabler of the rapid growth process of a young tech company and grow towards your goals, fun is guaranteed.

• Happy to be a Flipster: Stay tuned for regular team events and culture days that bring us together as Flipsters.

• Working abroad: At Flip you can also work abroad in the European Union. Let's talk about remote work in the interview.

At Flip, everyone is welcome - no matter what gender you identify as or how old you are. Sexual identity, origin, religion, world view and disabilities do not influence your potential job at Flip. The most important thing is that YOU fit in!
