Company Overview

Holafly is a high-growth scale-up revolutionising how businesses and travellers connect to the internet abroad. Since 2018, we’ve empowered travellers in over 200 destinations worldwide with secure and reliable eSIM solutions. With a team of 500+ professionals across multiple countries, we are scaling globally to support travellers with seamless, unlimited data connectivity.

We’re not just connecting people—we’re enabling freedom and peace of mind, ensuring our users stay connected from the second they land, wherever their journey takes them.

The Role

As a Senior Flutter Engineer, you will drive the technical evolution of our platform, directly impacting how 4 million+ active users experience global connectivity. You will bridge the gap between complex engineering and product value, taking full ownership of the lifecycle within a high-performing squad-based structure.

Key Responsibilities

  • Lead Product Discovery: Collaborate within cross-functional squads to transform complex problems into scalable technical solutions.

  • Architect for Scale: Build modular, high-performance features in a mature Monorepo environment using BLoC, auto_router, advanced network, and caching mechanisms.

  • Drive Quality Excellence: Maintain a regression-free environment by upholding high-coverage testing standards across unit, widget, and integration layers.

  • Optimize AI Workflows: Leverage and refine AI-driven development guardrails and LLM-based automation to accelerate delivery cycles.

  • Own the Outcome: Act as a product owner by proactively identifying UX/UI improvements that enhance traveller peace of mind.

  • Technical responsibilities: Contribute to a sophisticated stack managed with Melos, ensuring long-term codebase health and stability.

Qualifications

  • Product-First Mindset: Proven ability to align technical decisions with business impact and user experience.

  • Flutter Skills: Extensive experience building and maintaining large-scale production apps using Flutter and Dart.

  • Advanced Architecture: Deep expertise in state management with Bloc and advance dart concepts.

  • Testing Rigor: A disciplined "test-first" approach to engineering within complex, enterprise-grade codebases.

  • Collaborative Native: Exceptional communication skills tailored for a remote-first, squad-based environment.

Good to have

  • Experience managing Monorepos with Melos.

  • Hands-on experience building custom AI agents or advanced AI workflows.

  • 20 Days of PTO

  • Self development budget of $ 500
