Hi, I'm Daniele, VP of Engineering at Airalo!
Engineering drives Airalo’s eSIM platform. We build the product that lets millions of people connect instantly across the globe. The challenges are exciting: high-scale systems, carrier integrations, and products spanning both B2C and B2B. What matters most to us is creating an environment where engineers can do their best work. Real ownership, autonomy, and a direct link between what you ship and business outcomes are key. You’ll work with smart, motivated people who take their craft seriously. If you want to build things that matter at global scale, this is where you do it.
Airalo’s fully remote Engineering team is growing. In this role, you'll tackle complex technical challenges across our product ecosystem, helping build, innovate, and scale the platform that keeps millions of travellers connected worldwide.

Are you a talented engineer who loves building clean, functional code and solving technical challenges in PHP? Join our team as a Mid-Level Backend Engineer, where you will help evolve our global platform serving more than 20 million users.

Your main responsibilities will be to:
-
Develop and maintain robust backend services capable of handling high-volume global traffic.
-
Implement functional APIs and optimize query performance to ensure a seamless user experience.

Contribute to our modular architecture, helping us build resilient, service-oriented systems.
-
Write clean, maintainable code by applying SOLID principles, OOP best practices, and design patterns.
-
Master the art of debugging, identifying and resolving issues across our stack with precision.
-
Integrate asynchronous processes using queues and basic event-driven patterns to improve system efficiency.
-
Collaborate closely with Senior Engineers and Product teams to turn requirements into high-quality technical solutions.
