Product Engineer (Mobile)

Empower every employee.

Our mission is to be the world’s most used AI employee experience platform by changing the way frontline employees work.

Flip is the leading AI-powered employee experience platform for frontline workers. We’re transforming how the people who keep the world running — in retail, manufacturing, and logistics — do their jobs. One app. One touch. Everything they need.

Our mission: Connect every employee to everything they need in one touch.

Job description

We’re looking for a Product Engineer with a strong mobile specialization, a solid technical foundation, and experience working on SaaS products in agile environments. You’ll help us build high-quality user experiences in our Flutter app, with deep ownership of the user interface, interaction patterns, performance, accessibility, and the overall quality of our app. While your core focus will be mobile, we value an end-to-end product mindset and openness to extending your impact into backend or web systems where needed, bridging the gap with the support of AI.

What you can expect

• Deliver Features End-to-End: Ship user-facing features in our core domains with a focus on measurable outcomes.
• Cross-stack Development: Work hands-on with our mobile stack (Flutter, Dart) and extend into backend and web systems where appropriate.
• Build with Care: Develop software following modern practices: API-first design, code reviews, automated testing, and utilizing MR environments for exploratory testing before a merge.
• Validate What You Build: Instrument your features, observe how users actually behave, and use what you learn to refine, double down, or drop what doesn’t work.
• AI-Enabled Growth: Transition toward an AI-supported workflow, shifting focus from “writing code to spec” to holistic, end-to-end solution ownership.
• Own Your Features: Own the features you deliver — from technical decisions and cross-team alignment in our guilds to rollout and iteration.

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. Applicants coming from Kotlin Multiplatform, React Native, or native iOS/Android backgrounds are welcome. We value mobile depth and a willingness to ramp up on Flutter.

Must Haves:

• Mobile Proficiency: Hands-on experience with Flutter and Dart, including the widget/layout system and state management; a keen eye for performance, accessibility, and platform conventions.
• Cross-stack Mindset: Mobile is your primary discipline, but you’re open to stepping into backend or web development 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.
• 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.
• Agile Experience: Experience working on SaaS products in agile environments.

Nice-to-haves

• Experience with modular Flutter architectures — feature packages, modular navigation and DI across modules.
• Experience with the Apple App Store and Play Store release processes.
• Knowledge about analytics and error monitoring. (We use Mixpanel and Sentry)
• Experience with E2E or integration testing on mobile. (We use Patrol)

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!
