The posting

Alongside is a Portuguese company that partners with international organizations to build and scale exceptional tech teams.

We’re looking for a Senior Flutter Engineer to join an exciting international project within a global technology company. You’ll contribute to the development and evolution of a mobile application used by accounting professionals across Europe, working alongside international teams based in Portugal, the Netherlands, and India.

This is a hands-on engineering role where Flutter development, software architecture, and AI-assisted coding come together to build scalable, high-quality mobile solutions.

Responsabilities:

  • Design, develop, and deliver new features for mobile applications using Flutter (iOS and Android).
  • Take ownership of features throughout the development lifecycle, from specification to production.
  • Work with AI-assisted development tools, such as GitHub Copilot, to accelerate development while ensuring code quality.
  • Apply Spec-Driven Development practices using tools such as OpenSpec or similar.
  • Contribute to application architecture and state management using Riverpod.
  • Develop and maintain automated tests, including unit, widget, and integration tests.
  • Improve CI/CD pipelines and mobile application release processes.
  • Troubleshoot production issues and continuously improve application performance.
  • Collaborate with Product, Design, and Backend teams in an international environment.
  • Share technical knowledge and support other engineers through mentoring and code reviews.

Requirements

  • 5+ years of experience in software engineering, including at least 3 years working with Flutter.
  • Strong experience developing and maintaining mobile applications published on the App Store and Google Play.
  • Solid knowledge of Flutter, Dart, and state management, preferably Riverpod (BLoC or Provider experience is also valued).
  • Hands-on experience using AI coding tools such as GitHub Copilot, Cursor, Claude Code, or similar.
  • Familiarity with Spec-Driven Development approaches and tools such as OpenSpec or GitHub Spec Kit.
  • Experience with automated testing (unit, widget, and integration tests).
  • Good understanding of OOP, SOLID principles, design patterns, and REST APIs.
  • Experience with CI/CD pipelines for mobile applications.
  • Fluent English, both written and spoken.

Benefits

  • 6-month contract, with the possibility of extension depending on project needs (not guaranteed).
  • Hybrid working model, with 2 mandatory office days per week in Boavista, Porto.
  • Opportunity to work on an international project with experienced engineering teams.
  • Exposure to modern AI-first software development practices.
  • A collaborative environment where you can contribute to technical decisions and product development.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
