SysAdmin/SRE Mexico

Permanent employee, Full-time · Remoto

About this role

JOTELULU is a pioneering European cloud service provider, uniquely serving IT companies. Given that 80% of SMEs (Small and Medium-sized Enterprises) acquire their digital infrastructure through IT companies, we at JOTELULU have tailored our services to meet this significant demand. Existing cloud providers can’t sell directly to these SMEs, creating a unique niche that we effectively fill. Our array of services includes cloud datacenter, cloud storage, S3 storage, Remote Desktop, IP telephony, ... all designed to outperform the offerings of traditional cloud providers.
Our cloud infrastructure platform is self-managed, with multiple availability zones [AZ] across Europe, ensuring reliability and top-tier performance.

The challenge
We’re at a pivotal stage in the evolution of our cloud platform. To continue scaling efficiently and strengthening reliability, we are expanding our Operations & SRE capabilities. Our infrastructure supports mission-critical services for our customers, and ensuring performance, stability, and continuous improvement is at the core of our vision.
As a Site Reliability Engineer / Systems Administrator, your mission will be to monitor and optimize our cloud systems, automate processes, ensure effective incident management, and help us maintain a robust, scalable and secure infrastructure. You will play a key role in minimizing downtime, improving operational efficiency, and supporting sustainable growth.
You’ll be part of a highly collaborative engineering environment, working closely with DevOps, Product and Development teams to build reliable services from the ground up, enforce good operational practices and contribute to ongoing enhancements that impact thousands of users.
Collaboration will be essential. You will support critical infrastructure decisions, lead incident response, proactively detect risks and ensure that both technology and teams can continue to scale confidently.

What we expect from you

Proven experience managing large-scale cloud or MSP infrastructures.
Expert-level Linux systems administration (mandatory).
Experience with Windows Server (2012–2025) in production environments.
