Security Architect - Banamex
Banamex is transforming-and we're doing it from the inside out.
We're rebuilding one of Mexico's most iconic banks into a modern, secure, cloud-first financial platform that moves at fintech speed but with the scale and trust of a national institution.
As our Security Architect , you'll report directly to the CTO and become the architectural backbone of that transformation. Your mission: design the next-generation security fabric that protects millions of customers while empowering engineers to deliver faster, safer, and smarter.
You won't be maintaining controls-you'll be defining what secure banking looks like for the next decade . From Zero Trust architecture and DevSecOps pipelines to SPEI/CoDi payments, cloud workloads, and digital identity , you'll embed resilience, privacy, and compliance into every product we launch.
This is a role for someone who wants to build patterns that outlive them , influence architectural decisions at the highest level, and see their work ripple across the entire Mexican financial ecosystem.




If you want to make impact-not noise-this is where it happens.
What you'll own
- Target Security Architecture: Define and evolve reference architectures, control patterns, and guardrails for on-prem, cloud (AWS/Azure/GCP), and hybrid environments.
- Design Authority: Lead architecture reviews and formal threat modeling (STRIDE/LINDDUN); document risk-based decisions that stand up to audit.
- Zero-Trust & Identity: Drive identity-centric designs (OIDC/OAuth2/SAML, MFA, PAM), workload identity, micro-segmentation, and continuous verification.
- Data Security: Standardize encryption at rest/in transit, KMS/HSM usage, tokenization, data classification, DLP, and secrets management.
- Cloud & Container Security: Patterns for Kubernetes, serverless, and IaC (Terraform); adopt policy-as-code (OPA/Conftest), image signing, and runtime protections.
- DevSecOps Enablement: Embed SAST/DAST/IAST/SCA and IaC scanning into CI/CD; c
