Infrastructure & Support Engineer (Mid)

Description

**WHO ARE WE?** ------------------- At **Libelium**, we develop innovative technology solutions based on **data**, powered by **digital twins**, often enriched with local information captured by our **IoT** devices. Our technology enables **smart cities** to optimize decision-making and helps critical infrastructures improve efficiency and security through **advanced environmental monitoring**, such as in electric power transmission. Our IoT devices connect the physical world with the digital one via our platform ️**iris360**, driving sustainability, productivity, and **datocratization** for enterprises and cities across more than **120 countries**. We firmly believe that data is the new language of communication among governments, businesses, and citizens — facilitating a positive impact on our planet. * **Our MISSION** is to help businesses and cities harness the full potential of IoT to build a more **competitive, sustainable, and datocratized** society. * **Our VISION** is to be leaders in designing comprehensive, precise, robust, secure, and environmentally respectful **IoT products and solutions**, collaborating with top professionals. * **Our VALUES** are the people who make up **Libelium**, committed to developing professional solutions to address global challenges and improve our society. **WHAT ARE WE LOOKING FOR?** ------------------ At **Libelium**, we are seeking an Infrastructure \& Support Engineer with 3\-4 years of professional experience in a similar role. You will be responsible for supporting the construction and evolution of our cloud and on\-premise infrastructure (AWS, OVH, and local servers), with a focus on containers and Kubernetes, while also providing internal technical support, applying networking knowledge, and using no\-code automation to improve both your own and other teams’ processes. You will maintain constant contact across the company (Support), Product, and Consulting teams (infrastructure requests, expiration management, cost reviews) — so communication skills matter just as much as technical expertise. This is a growth-oriented position: we seek someone with a solid foundation and strong motivation to progressively assume greater technical responsibility. You will join the Digital \& Data department — the company’s technological engine: infrastructure, automation, data, and AI serving the business. We operate under a philosophy of continuous improvement and rapid iteration, and we seek someone eager to bring a modern infrastructure perspective to a small, high-impact team. **RESPONSIBILITIES** * Deploy and maintain cloud infrastructure (AWS, OVH, Google Cloud) and on\-premise servers, including environments with Kubernetes and AI machines for internal tool consumption. * Deploy and maintain internal corporate tools. * Provide internal technical support across the entire company via our ticketing system (users, devices, access, incidents). * Serve as the primary point of contact for Product and Consulting teams regarding infrastructure requests, project expiration management, and cost reviews — proposing improvements to communication methods and workflows with these areas. * Automate infrastructure tasks: Infrastructure as Code, scripting, CI/CD. * Apply networking knowledge (firewalls, routing, VLANs, subnetting) to contribute to maintaining the corporate network infrastructure, alongside the Security \& Compliance lead. * Contribute to infrastructure cost management, tagging, and access control. * Manage software licenses (SaaS and installed software): renewals, usage tracking, and cost optimization. * Use no\-code/low\-code tools to automate tasks within your own and other departments when they add efficiency. * Proactively propose technical improvements and help modernize our infrastructure practices. **REQUIREMENTS** * 3\-4 years of experience in infrastructure, systems, DevOps, or advanced technical support roles. * Knowledge of cloud environments and services (AWS, OVH, Google Cloud) and on\-premise servers — we do not seek a cloud-only profile. * Practical experience with AWS, OVH, and Google Cloud consoles — deep mastery of all three is not required, but hands-on experience with more than one provider and comfort navigating between them is essential. * Hands-on Kubernetes experience (deployment, basic troubleshooting, container orchestration concepts). * Solid networking knowledge (firewalls, routing, VLANs, subnetting) — equivalent to CCNA level or gained through experience. * Scripting (Bash, Python) to automate repetitive infrastructure tasks. * Familiarity with IaC tools (Terraform, Ansible, or similar) — desirable. * Experience providing internal technical support (tickets, incidents). * Practical knowledge of AI and no\-code automation tools (N8N, Zapier, Make, or similar) — we do not seek someone who develops AI models, but rather someone capable of using these tools to automate processes, either for their own or other departments’ needs. * Experience managing software licenses (SaaS and installed software): renewals, usage control, and cost optimization. * Strong communication skills: this role regularly interacts with both technical and non-technical teams, not only infrastructure specialists. * Proactive attitude: you feel uncomfortable leaving manual processes unautomated, and you don’t wait for others to tell you what to improve — whether in infrastructure, costs, or coordination with other departments. * Eagerness to learn and grow technically — this role offers clear career progression within the team. **PREFERRED QUALIFICATIONS** ------------- * Certifications: CCNA (networking), AWS Certified SysOps/Solutions Architect Associate, Google Cloud Associate/Professional, CKA/CKAD (Kubernetes). * Experience with monitoring (Grafana, Prometheus, Zabbix) and observability tools. * Prior experience in hybrid environments (cloud \+ on\-premise simultaneously). * Experience with managed AI services on Google Cloud, AWS, or OVH. * Prior experience automating processes with no\-code tools (N8N, Make, Zapier, AppSheet, etc.). * Degree in Computer Engineering, Telecommunications, or related field (not mandatory if equivalent experience exists). ### **What we are NOT looking for in this role** This is not an AI development or data science role — training models or coding analytical pipelines is not required. We seek someone who knows how to use AI and no\-code tools as additional levers of efficiency — just as they already use scripts or IaC. **WHY LIBELIUM?** ---------------------- * Join a **dynamic**, growing company actively pursuing **international expansion**. * Receive a **Welcome Pack**, and onboard through a structured process ensuring clarity from day one. * Be part of an international **pioneer in IoT and digital twin technologies**. * **Develop personally and professionally** alongside the Libelium team. * Discover our **Family-Friendly Company** initiatives — especially those promoting work-life balance and flexibility. * Enjoy a **hybrid work model** combining remote and office work to support work-life balance while still enjoying team interaction. * Complimentary **coffee service** at the office for all team members. * Office locations at **WTC Zaragoza and Urban Center Murcia**, surrounded by a wide range of amenities. * A dedicated **Teaming team** organizing leisure activities. * Competitive compensation: **Fixed \+ Variable salary \+ Flexible Benefits**. * **Employee Club**: discounts at various services and establishments. * User-friendly **Employee Portal**, providing all daily operational information you need. * Permanent contract * Full-time * Hybrid (Zaragoza, Zaragoza, Spain)
