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.

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
Agile Experience: Experience working on SaaS products in agile environments.

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)

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.

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.
