Lead end-to-end security architecture for platforms, applications, data, and infrastructure in multi-cloud/hybrid environments.
Produce HLD/LLD, reusable reference architectures, and design patterns for critical controls (segmentation/zero trust, identity, data protection/crypto, runtime protection, observability, recovery).
Embed secure-by-design/default principles through threat modeling, attack-surface reduction, least privilege, and service-to-service trust.
Cloud & Platform: Secure landing zones, guardrails, workload identity, and scalable segmentation patterns.
Identity & Access: Workforce & customer IAM patterns (federation/SSO, least privilege, privileged access).
Data Security & Privacy: Classification and encryption standards; practical key management and privacy-by-design.
Application & API: Service-to-service trust, API gateway & microservices patterns, secrets handling, abuse-case–aware designs.
Detection & Resilience: Telemetry baselines, reference detection patterns, continuity/recovery architecture.
Secure Integrations: Safe data flows to risk engines, behavioral analytics, and device intelligence; align fraud signals with security detections.
Governance: Support rule/model governance (explainability, lineage, rollback) with privacy-preserving designs.
Product Partnership: Collaborate with Fraud PO/Tribe on capability roadmaps and OKRs; treat fraud controls as first-class architecture components.
Curate and evolve Security Patterns and GCash Gold Standards; maintain a versioned library with adoption guidance, baselines, and controls mapping.
Translate BSP expectations and global frameworks (ISO 27001, NIST 800-53/CSF, PCI DSS, CIS) into clear design-time and run-time acceptance criteria.
Operate architecture reviews and threat modeling; track risks and decisions to closure with auditable evidence.
Lead security validation: ASV/BAS, attack-path analysis, purple-team exercises, chaos/resilience testing, and continuous control monitoring with evidence automation.
Run market scans, RFP/RFQ, bake-offs, and PoCs; evaluate fit, integration complexity, telemetry quality (OCSF where applicable), and total cost of ownership.
Work closely with Product Owners and Tribe Leads to map capability gaps → epics → increments, aligning choices to value streams and OKRs.
Negotiate with vendors on SLAs, security commitments (SBOM/VEX, secure configs), scalability, and commercials/ELAs; define exit criteria to avoid lock-in.
Establish joint success plans (enablement, runbooks, adoption KPIs), manage escalations, and influence vendor roadmaps to GCash needs.
Maintain a curated tech radar (adopt/trial/assess/hold) and drive rationalization across the stack.
Embed with Tribes/Squads; participate in backlog refinement, sprint planning/reviews/retros to land security without blocking delivery.
Define security Definition of Ready/Done and light policy-as-code guardrails so squads can self-serve safe defaults.
Provide clear design decisions and trade-offs; mentor engineers and contribute to internal guilds/chapters.
7+ years in security architecture/engineering with shipped, large-scale systems (finserv/fintech a plus).
Depth in at least two of: cloud/platform security, identity & access, data protection/crypto, network segmentation/zero trust, platform/endpoint security; working knowledge across adjacent domains.
Hands-on familiarity with Kubernetes/containers, service mesh, API gateways, IaC (e.g., Terraform), secrets management, and modern telemetry.
Strong threat modeling, architectural documentation, stakeholder communication, and decision-recording skills.
Familiarity with BSP regulations and global frameworks (ISO 27001, NIST 800-53/CSF, PCI DSS, CIS Benchmarks, MITRE ATT&CK).
Exposure to fraud/risk tech (risk engines, behavioral analytics, device intelligence) and model governance.
Experience with SIEM/XDR/SOAR/UEBA, CNAPP/CSPM, API security platforms, PAM/IGA/CIAM, and data protection stacks (KMS/HSM, tokenization).
Track record leading RFPs/PoCs and negotiating commercial/technical terms with vendors and cloud providers.
