Ability to define and verify retention, encryption, cataloging, restoration, and secure deletion policies.
• Continuity and resilience: mastery of RPO and RTO concepts, application consistency, disaster recovery, and periodic restoration and failover testing, including dependency analysis and evidence validation.
• Service management: experience in ITIL processes, observability, incident, problem, change, capacity, availability, configuration, and continuity management, using ITSM tools and maintaining reliable information in CMDB.
• Providers: experience supervising outsourced services, contracts, service level agreements, indicators, risks, obsolescence, technical escalations, and improvement plans, maintaining traceability of decisions and commitments.

• Specialized training in storage, data protection, business continuity, and/or IT service management will be valued.
• Experience in financial sectors, critical infrastructures, or regulated environments, with reinforced controls over operational resilience, security, traceability, and data preservation.
• Knowledge of cyber-resilience applied to backup: immutability, segregation, least privilege, ransomware protection, and recoverability validation.
• Experience in migrations of arrays or backup platforms, data center consolidations, technological renewals, and controlled asset retirements.
• Technical certifications from relevant manufacturers, ITIL, business continuity, security, or project management.
• Analytical capacity, service orientation, executive and technical communication, autonomy, prioritization under pressure, and effective coordination of internal teams and third parties.
• Ability to document procedures, architectures, responsibility matrices, risks, test evidence, capacity reports, and remediation plans in a clear and auditable manner.

At Cajamar Tecnología, we need to hire someone for the IT Infrastructure and Operations office.

You will be responsible for ensuring the availability, integrity, protection, and recovery of corporate information through the technical and operational governance of storage and backup services in a complex, critical environment subject to high continuity requirements.

The position must supervise platforms, capacities, service levels, risks, and evolution plans; coordinate the service provided by external providers in charge of the operation and administration of the technological infrastructure; lead the response to serious incidents; and guarantee that copies and restorations meet recovery objectives, internal policies, and applicable regulatory requirements.

• Govern the end-to-end operation of storage and backup platforms, guaranteeing availability, performance, integrity, security, and compliance with service levels.
• Define, review, and control copy, replication, retention, archiving, encryption, immutability, and restoration policies, aligning them with service criticality and RPO and RTO objectives.
• Supervise daily the success of copies, exceptions, capacity consumption, infrastructure health, and performance trends, promoting preventive actions before they affect the service.
• Technically lead the resolution of critical incidents and recurring problems, coordinating manufacturers, providers, and systems, database, communications, security, and applications teams.
• Plan and execute periodic restoration and disaster recovery tests, documenting scope, results, deviations, evidence, and improvement plans until their closure.
• Manage capacity, demand, and obsolescence through forecasting, thresholds, growth analysis, and investment proposals that avoid risks of saturation or lack of support.
• Evaluate designs, changes, migrations, and new needs, ensuring their compatibility, recoverability, monitoring, support, documentation, and reversibility before moving to production.
• Maintain up-to-date inventories, dependency relationships, responsibility assignments, and configuration data, avoiding orphaned assets, unmonitored assets, or incorrectly classified assets.
• Control the service provided by third parties through SLA, KPI, follow-up meetings, escalations, root cause analysis, commitments, and action plans with owners and target dates.
• Identify operational, technological, and security risks; propose mitigation measures; and prepare executive information and evidence for committees, audits, and continuity exercises.
• Drive automation, standardization, observability, and continuous improvement to reduce manual tasks, errors, diagnostic times, and dependence on individual knowledge.
