Job description

Company Overview:

Holafly is a high-growth scale-up revolutionising how businesses and travellers connect to the internet abroad. Since 2018, we’ve empowered travellers in over 200 destinations worldwide with secure and reliable eSIM solutions. With a team of 500+ professionals across multiple countries, we are scaling globally to support travellers with seamless, unlimited data connectivity. We’re not just connecting people—we’re enabling freedom and peace of mind, ensuring our users stay connected from the second they land, wherever their journey takes them.

The Role:

You will be the architect of our cloud foundations, ensuring security is baked into our DNA rather than bolted on as an afterthought. Your work directly enables our engineering teams to scale safely, protecting the connectivity of millions of global travellers.

Key Responsibilities:

• Design and operate the GCP cloud platform foundations, owning the full lifecycle of infrastructure and security.
• Automate everything via Terraform and Ansible, eliminating "snowflake" servers and manual console configurations.
• Maintain and scale GKE clusters, managing workloads, network policies, and cluster lifecycles.
• Strengthen our security posture by implementing least-privilege IAM, image scanning, and SOPS-based secret management.
• Optimise CI/CD pipelines using Cloud Build and GitHub to ensure high-quality, secure code deployments.
• Enhance observability and incident response through OpenTelemetry and OpenSearch to ensure 24/7 platform reliability.

Qualifications:

• Proven experience managing Google Cloud Platform (GCP) and Kubernetes (GKE) at scale.
• Expertise in Infrastructure as Code (IaC) specifically using Terraform.
• Strong proficiency in Python or Bash for high-level automation and tooling.
• Deep understanding of container security, including Docker and artifact vulnerability scanning.
• A "security-first" mindset with experience in secret management and supply-chain hygiene.

Nice to Have:

• Experience with OpenTelemetry or OpenSearch instrumentation.
• Familiarity with SonarQube for automated code quality gates.
• Previous experience in high-growth scale-ups or the travel-tech industry.

Benefits & Perks

• 25 Days of PTO
• 5% pension contribution
• € 3000 for Medical/Health coverage
• Self development budget of $ 500
