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.

As our Senior DevSecOps Engineer, you will be the guardian of Airalo’s global infrastructure and applications. This isn't just about maintaining compliance, it’s a hands-on opportunity to spearhead our shift-left security strategy, centralise AWS governance, and proactively outsmart malicious attacks. If you are excited to design robust defences that slash attack vectors by 50% while scaling a secure ecosystem for millions of travellers, this is your chance to take true technical ownership.
