Agentic Product Engineer | Internship | Full-stack | Saily
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
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.
