What you'll be doing

You will build and operate the security controls that protect Zenoti's cloud estate, while partnering closely with InfoSec, Platform, and Engineering to enforce these controls.

• Own network architecture and connectivity. Design, build, and run the network backbone of a distributed, multi-tenant SaaS estate: vWAN/hub-spoke, ExpressRoute/VPN, cross-cloud (AWS↔Azure) connectivity, private endpoints, DNS, routing, and segmentation, engineered for redundancy and tested failover.

• Secure the edge and perimeter. Run the WAF, DDoS protection, Front Door/CDN, firewalls, and egress control, with no single points of failure, and keep network visibility high through flow analytics and cross-cloud path monitoring.

• Automate everything that repeats. Treat network and security as code: secure-by-default Terraform modules, IaC scanning gates, drift detection, policy-as-code (OPA, Azure Policy, SCPs), automated evidence collection, and certificate and secrets lifecycle automation.

• Operate detection, response, and resilience. Lead detection engineering, SIEM tuning, and incident command with RCA-to-control feedback loops, plus DR and ransomware-recovery architecture with failover runbooks tested on a schedule.

• Keep us continuously compliant. Maintain a control registry mapped to SOC 2, PCI-DSS, HIPAA, and regional privacy laws, and govern identity, PKI, and encryption in line with InfoSec policy.

• Be the architecture authority and set direction. Run design reviews and readiness assessments for new platforms and tools, manage risk-acceptance workflows, own the roadmap, mentor engineers, and give leadership clear, metric-anchored risk reporting.

What you'll bring

• 8+ years designing and operating infrastructure in Azure (primary) and AWS , with deep expertise in both network and security.

• Deep cloud networking: vWAN/hub-spoke, ExpressRoute/VPN (IPSec), BGP and routing, DNS, load balancing, private connectivity, and firewall and WAF management, including diagnosing complex cross-cloud connectivity issues.

• Security fundamentals: TLS/PKI, IAM, SIEM, threat analysis, and EDR and vulnerability/patch management across Windows and Linux.

• Strong automation skills: production IaC (Terraform preferred; ARM/Bicep/Ansible a plus), CI/CD pipeline integration, and scripting in Python, PowerShell, or Bash to eliminate manual toil.

• Multi-tenant SaaS architecture: tenant isolation, blast-radius thinking, and data residency across regions, including GDPR and regional laws.

• Workload and data security: Kubernetes (AKS/EKS) hardening, encryption and key management, and SQL Server and PaaS datastore hardening.

• Brownfield pragmatism: migrating legacy estates to secure baselines without outages, through phased adoption.

• Solid command of SOC 2, PCI-DSS, and HIPAA audits, including customer security questionnaires.

• Clear written communication: ADRs, and translating risk into business terms for leadership and auditors.

• Ability to influence through technical depth in a fast-paced, scaling SaaS environment.

Nice to have: AZ-500/SC-100, AWS Security Specialty, CISSP/CCSP, CKS.
