Freelance Flutter App Developer Jobs (NOW HIRING)

Hudu is hiring a remote candidate for Flutter Engineer. This is a full time position. Work location: USA. The role typically involves technologies such as JavaScript, Rails, Ruby, Java, Linux, REST.

Hudu is a fast-growing SaaS platform built exclusively for IT professionals and Managed Service Providers (MSPs). We give teams a single, secure, and beautifully simple place to store, organize, and share everything that keeps modern IT environments running: passwords, network documentation, processes, assets, client knowledge, and more. By replacing scattered spreadsheets, outdated wikis, and a dozen disconnected tools with one unified, customizable solution, Hudu helps thousands of IT teams save time, reduce risk, deliver better service, and scale with confidence.

Our mobile app is built with Flutter and Dart, using Riverpod for state management. Our Radar Service and Agent apps are Dart console apps running as Windows services using FFI to query lower-level native APIs. We use WIX and Inno Setup as installer tools to build our exe/msi installers. Our core web app (Hudu) is built with the latest Ruby on Rails and Hotwire. Communication between apps are supported via OAuth 2.0. For testing we use rspec, vitest, flutter test, test (dart), and Mockito. Our APIs are based on REST and documented with Swagger. We use Github for our PR Review Process, and Github Actions for our DevOps Pipeline. We use Sentry for error reporting.

• Work on Dart console apps for Radar, including Windows services that use FFI for native API access

• Collaborate with UX design and product management teams to brainstorm new and existing requirements


• Implement new features, new products, and help to improve existing features


• Consult with managerial, engineering, and technical personnel to clarify program intent, identify problems, and suggest changes

4+ years of experience developing software with Dart and Flutter.

• Proven experience building and maintaining a production Flutter/Dart mobile app.


• In-depth experience building and maintaining RESTful APIs.


• Proven experience translating UI/UX designs into responsive, user-friendly mobile interfaces.

• Bonus Points:

• Experience with FFI or calling native Windows APIs from Dart — this would let you contribute to the Windows services that power Radar's data collection.

• Experience with Ruby on Rails and Hotwire (Stimulus.js and Turbo) — our core web app (Hudu) and Radar's backend are both Rails apps, so Rails experience would let you contribute across that side of our stack as well.
