App & Software Development in Denmark – Life Science Specialists

Flutter Developer - Mobile Solutions for Life Science Innovation

Flutter developer creating mobile applications for Life Science with cross-platform development environment

Flutter Developer - Architecture & Design Patterns Expert

We're seeking an experienced Flutter Developer who is passionate about software architecture, design patterns, and writing clean, maintainable code. At Bon.do, we're architecture experts who happen to work in Life Science - not the other way around.

You'll work with a team that lives and breathes SOLID principles, Clean Architecture, and modern architectural patterns like MVVM, Repository, and Factory patterns. We're first movers in adopting best practices - Riverpod, Bloc, and cutting-edge Flutter patterns are our daily tools, not buzzwords.

Why This Role Matters

Your primary focus is building architecturally sound, scalable mobile applications using Clean Architecture principles. We apply SOLID principles, design patterns, and modern state management (Riverpod, Bloc) to create maintainable codebases that stand the test of time.

Architecture-First Development Culture

We're obsessed with software architecture. Every code review discusses SOLID principles. Every feature starts with architectural design. We use Factory, Repository, Observer, Strategy, and Adapter patterns daily. Our codebase follows Clean Architecture with clear separation of concerns - and we're proud of it.

What You'll Be Working On

You'll architect and build sophisticated mobile applications using industry-leading patterns and practices. Your work happens to be in Life Science, but your focus is on architectural excellence:

  • Clean Architecture Implementation: Building scalable apps using layered architecture with clear separation between presentation, domain, and data layers
  • Design Pattern Application: Implementing Repository, Factory, Observer, Strategy, and Adapter patterns in real-world scenarios
  • Advanced State Management: Architecting complex state flows using Riverpod and Bloc with dependency injection
  • SOLID Principles in Practice: Writing code that exemplifies Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion
  • Architecture Reviews: Participating in design discussions and code reviews focused on architectural quality and maintainability

What We're Looking For

Technical Requirements

  • 2-4 years of Flutter development experience with demonstrable focus on architecture
  • SOLID Principles: Deep understanding and practical application of all five SOLID principles in Flutter/Dart
  • Clean Architecture: Experience implementing layered architecture with clear boundaries between layers
  • State Management Architecture: Advanced experience with Riverpod or Bloc, including dependency injection and testable patterns
  • Design Patterns: Hands-on experience with Repository, Factory, Observer, Strategy, Adapter, and other Gang of Four patterns
  • MVVM & Presentation Patterns: Strong understanding of presentation layer architecture and separation of concerns
  • Code Quality Advocate: Experience with architectural reviews, refactoring, and mentoring others on design principles

Soft Skills & Cultural Fit

  • Communication: Excellent English communication skills for our international team
  • Architecture-First Mindset: You think about scalability, maintainability, and architectural implications before writing code
  • Code Review Culture: You enjoy giving and receiving architectural feedback in code reviews
  • Continuous Learning: You're excited about new architectural patterns and first-mover adoption of best practices
  • Quality Obsession: You believe clean code and good architecture are non-negotiable, not nice-to-haves

Why Architecture Matters at Bon.do

We're not just talking about architecture - we live it every day. Here's what makes our development culture unique:

Architecture-First Culture

  • Design Pattern Code Reviews: Every pull request includes discussion of SOLID principles, design patterns, and architectural decisions. We don't just check if code works - we evaluate if it's architecturally sound
  • Architecture Before Code: New features start with architectural design sessions. We discuss Repository patterns, state management strategies, and layer boundaries before a single line is written
  • Patterns in Production: Factory pattern for object creation, Repository for data access, Observer through Riverpod/Bloc, Strategy for algorithm selection, Adapter for third-party integration - these aren't academic concepts, they're our daily tools
  • First Mover Mentality: When Riverpod 2.0 launched, we were early adopters. When Flutter 3.0 introduced new patterns, we integrated them immediately. We lead, we don't follow

Real-World Architecture Examples

Here are concrete examples of how we apply architectural principles:

  • Clean Architecture Layers: Presentation (UI + ViewModels) → Domain (Use Cases + Entities) → Data (Repositories + Data Sources). Every developer knows which layer they're working in and respects the boundaries
  • Dependency Inversion: Our presentation layer depends on domain abstractions, never concrete implementations. All dependencies point inward
  • Testability by Design: Because we follow SOLID and use dependency injection, our codebases have high test coverage without painful mocking
  • Continuous Refactoring: We allocate time for architectural improvements. Technical debt is actively managed, not accumulated

Ready to Make an Impact?

If you're passionate about software architecture, excited about applying SOLID principles and design patterns in real-world applications, and want to join a team of architecture enthusiasts who happen to work in Life Science, we'd love to hear from you.
