Engineering

At Saily, we're removing the hassle of staying connected while travelling — no roaming fees, no plastic SIM cards, just fast, secure mobile data in 200+ destinations. Saily has millions of paying customers, with hundreds of thousands of travellers using the product at any given moment.

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

The Engineer is the builder, responsible for solving problems end-to-end — from idea to production.
AI Agents are the enablers who handle repeatable tasks and help engineers maximise their impact.
Everyone contributes to making Saily effective by identifying new areas for improvement and delegating them to agents.
Curiosity, learning, and sharing are everyone's responsibility.
Our customers — travellers who rely on seamless connectivity — are never lost from focus.

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

Main Responsibilities

Own and maintain infrastructure configuration for all application services, including cloud cost management and optimisation.
Own and improve the CI/CD process for developers across the organisation — including setting up repositories and hosting new services across teams (backend, web, mobile, QA).
Own observability — logging, metrics, and alerting — across the organisation.
Define and maintain Infrastructure as Code using Terraform and Terragrunt, with the scope expected to grow.
Contribute to our internal AI tooling platform, enabling engineers to deploy new tools independently.
Contribute to infrastructure security.
Improve developer experience — from pipeline speed to deployment reliability.
Design processes with ease of use and simplicity in mind — self-explanatory rather than over-engineered, with documentation where it genuinely helps.

Core Requirements

2+ years of hands-on DevOps or infrastructure engineering experience.
Strong Linux knowledge.
Solid understanding of networking protocols and IP networking fundamentals.
Hands-on experience with configuration management tools (Ansible or Helm).
Practical experience with IaC — not just the concept, but its application in real environments.
Experience with at least one major cloud provider (AWS, GCP, or Azure — we'll help you adapt if needed).
Experience building and maintaining CI/CD pipelines.
Experience with observability tooling.
AI coding agents are part of how we work every day — comfort with them is a must.
