Internship

Job Overview

At Saily, we’re removing the hassle of staying connected while traveling — no roaming fees, no plastic SIM cards, just lightning-fast, secure mobile data in 200+ destinations. Saily has millions of paying customers and hundreds of thousands travelers browsing through Saily at any given moment.

To build the best product for our customers we foster AI-native Product Engineering culture, where:

- The Engineer is the builder, who is responsible for solving customer problems end-to-end (idea to production)
- AI Agents are the enablers who write most of the code and solve repeatable  tasks to  help the Engineers  maximize their impact
- Everyone contributes to making Saily effective by suggesting new areas for improvement to delegate to agents and then implementing the changes
- Curiosity, learning and sharing are everyone's responsibility
- Customer, having a comfortable, connected, hassle-free journey is never lost from the focus

We value growth over comfort, contribution over hierarchy, and impact over process. At Saily, we believe in giving sharp people context, autonomy, and AI as their multiplier to allow them to just do their best work.

If you want to start your engineering career by doing real work - not exercises - join Saily.

We’re looking for Trainee Engineers who think clearly, learn fast, and take ownership. Curiosity matters. So does discipline.

You’ll work with a strong team on real problems from day one. You’ll get support when you need it, and ownership when you’re ready for it.

We move fast, use AI as a default, and focus on helping you build good engineering habits early.

This is a 3 months full-time paid internship. Prove yourself, perform well, and your contract will get upgraded to a full-time employment.

If that sounds like your kind of start, apply.
