Agentic Product Engineer | Junior | 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

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.

We’re opening our doors to talented junior engineers - because impact isn’t measured in years of experience. It comes from your drive to learn, your discipline, and a sharp mind. It’s about building and shaping what’s around you - and Saily will give you the room to do exactly that.

What can you expect from us? Hands-on experience with AI-assisted software development, shared openly. Full freedom to use whatever learning resources you need to keep up. A product that’s successful, impactful, and technically challenging - something you’ll actually want to build.
