About the Role
We are an established SaaS company in Mexico City, recently acquired by an international corporation. You will own our IT and security function end-to-end — managing a complex technical environment, ensuring operational continuity, and leading key infrastructure modernization initiatives. This is a hands‑on role with real ownership and direct impact on how the business operates and protects itself.
Who You Are
You are a self‑directed, hands‑on technologist who gets things done in messy, real‑world environments. You take ownership, sweat the details, and hold yourself to results — not effort. You communicate clearly with both technical and non‑technical stakeholders, and you're comfortable working within a structure that has both local and corporate expectations.
Responsibilities
- Manage and harden legacy Unix and Linux environments; maintain operational stability and security posture
- Lead infrastructure migration and technology modernization projects, including cloud environments (AWS, Azure)
- Define, document,



and implement IT and information security policies across the organization
- Administer the Azure tenant and Microsoft 365 suite, including Entra ID, Intune, and Defender
- Manage all employee endpoint security: CrowdStrike, Cloudflare, ActZero, and KnowBe4 platform
- Own the full IT employee lifecycle: onboarding, offboarding, asset inventory, and access control
- Deploy and enforce MFA and access controls across all systems and users
- Design, implement, and maintain backup and disaster recovery (DR) practices; conduct regular testing
- Manage key vendor relationships (hosting, licensing, security services) and associated IT budgets
- Manage and optimize API integrations with external platforms and service providers
- Produce and maintain corporate security reporting for local and parent‑company stakeholders
- Implement and enforce network security policies: firewall configuration, VPNs, and network access controls
