Flutter Developer

Planet Argon provides dependable support and maintenance of existing legacy applications for a variety of clients in different industries. We take care of feature updates, bug fixes, and performance improvements.

We’re looking for an experienced Flutter (Dart) Developer for a short-term contract to help bring a client’s web-based tool to life on mobile. The primary objective is to recreate essential features and workflows in Flutter, using an existing backend API.

Note: While Flutter/Dart is preferred, we’re open to React Native if your experience is significantly stronger in that ecosystem.

You’ll be contributing to My Storage Navigator, a mobile app that mirrors the functionality of an existing web application used for managing self-storage operations. Your first task will be refining the Login flow and then expanding to build additional UI screens, handle API integrations, and ensure user data is handled securely and efficiently.

This contract will run from July through September 2025, with the following estimated workload:

• July: ~40 hours
• August: ~40 hours
• September: ~10 hours

This is a remote, part-time contract with an estimated commitment of 90 hours total.

We're looking for contractors that embody our core values:

• PROACTIVE - We actively seek opportunities to improve our client’s products, our processes, and our abilities.
• CURIOUS - A natural curiosity for the undiscovered results in remarkable work for our clients – and stronger connections for our team. We ask questions, learn, and aren't afraid to fail.
• DEPENDABLE - We are invested in our work. We manage expectations. We support our clients and teammates. We hold ourselves, our teammates, and our clients accountable.
• VERSATILE - We readily adapt to change and encourage innovation because our team and work are transparent and flexible.
• DELIGHTFUL - We choose to set a mindful, positive tone that allows everyone to flourish.
