  • Define and maintain architecture standards, reference architectures, and reusable control patterns
  • Lead architecture reviews for new initiatives, system changes, and product programs
  • Manage and provide technical direction to a team of security architecture resources
  • Govern architecture documentation, decision records, and compliance evidence artifacts

Cloud Security Architecture & Engineering
  • Own cloud security architecture, landing zones, guardrails, and controls across AWS and Azure
  • Oversee cloud security engineering, posture assessments, IaC security, and CI/CD pipeline hardening
  • Enforce security-by-design and least-privilege across cloud networking, identity, and workloads
  • Design and oversee security controls for AI/ML services (e.g., AWS Bedrock, Azure OpenAI, SageMaker)
  • Govern enterprise AI tool consumption to prevent sensitive data from reaching third-party LLM APIs or AI-enabled SaaS platforms

Security Posture, Detection & Monitoring
  • Assess and improve cloud security posture using telemetry, CSPM, and logging platforms
  • Identify misconfigurations, control gaps, and emerging risks across cloud environments
  • Partner with Security Operations to improve visibility and response for cloud-related risks
  • Critically assess AI-driven security tooling (CSPM, SIEM) to ensure detection quality

Product Security Architecture
  • Own architecture oversight across Neptune's AMI product security program - meter endpoints, RF/cellular, cloud pipelines, and SaaS
  • Direct product security architecture resources in threat modeling, design reviews, firmware assessments, and compliance translation
  • Ensure product security aligns with IEC 62443, NIST SP 800-82, NIST SP 800-218 (SSDF), and SOC 2
  • Serve as security architecture liaison between Cybersecurity and product development teams

Incident Response & Readiness
  • Provide technical guidance during cloud and product security incidents - investigation, containment, and remediation
  • Drive root cause analysis and architectural improvements following incidents
  • Participate in tabletop exercises and threat modeling activities

Governance, Compliance & Collaboration
  • Ensure environments align with internal standards and frameworks (CIS, NIST, IEC 62443, SOC 2, Roper Cyber Controls)
  • Support audit and compliance efforts with architecture artifacts and technical evidence
  • Research emerging threats and technologies to proactively strengthen defenses
  • Leverage AI-assisted tools to accelerate security engineering, threat modeling, and compliance automation

Relevant Platforms (experience with several expected):
  • Cloud: AWS, Azure
  • Cloud Security & Posture: AWS Security Hub, AWS Config, Azure Policy, CSPM tools
