Full job description

Please note, you'd be expected to come to office only 3-4 times per Month, so candidates need to be based in Ireland.

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 Fullstack engineer, you will bridge the gap between high-performance UI and the future of connectivity by building AI-integrated web experiences. Your mission is to ensure our global platform remains resilient, scalable, and intuitive, directly impacting how millions of users access the internet.

Key Responsibilities

Architect scalable UIs using React and TypeScript, ensuring every component meets our high standards for performance and accessibility.
Backend Support & Integration: Develop and maintain efficient Node.js RESTful APIs to support frontend requirements and business logic.
API Standards: Experience working with OpenAPI (Swagger) for documenting and defining robust API contracts.
Drive technical excellence by implementing Test-Driven Development (TDD) and comprehensive testing suites to maintain a robust codebase.
Collaborate on AI-driven features, integrating intelligent workflows into the frontend to enhance the customer journey.
Maintain design consistency by leveraging Tailwind CSS and shadcn/ui to build beautiful, functional interfaces.
Optimize full-stack efficiency by collaborating on Node.js services and RESTful API integrations.
Lead by example in code quality, conducting peer reviews that foster a culture of clean, maintainable code.

Qualifications

Strong expertise in React and TypeScript, with a deep understanding of modern state management.
Node.js Proficiency: Solid experience building and consuming RESTful APIs using Node.js (Express, NestJS, or similar).
Proven commitment to Quality through TDD and experience with Testing Library/Jest.
Proficiency in Tailwind CSS and component libraries like shadcn/ui for rapid, high-quality development.
Familiarity with AI integration, understanding how to connect frontend layers with LLMs or AI services.

Nice to Have

Testing Standards: We value consistent quality; we use twd-js as our core frontend testing tool to automate development chores and maintain a high-quality codebase. Familiarity with it (or a similar testing mindset) is a plus.
DevOps Basics: Experience with Docker and containerized environments to ensure local-to-production consistency.
Cloud & CI/CD: Knowledge of Google Cloud Platform (GCP) infrastructure and hands-on experience with CI/CD pipelines.
