Quanta Services is seeking an IT Security Architect to join our IT Security team, reporting to the Director, IT Security. This is a senior, hands-on architecture role focused on securing the organization's multi-cloud footprint as Quanta executes a cloud-first transformation across 100+ operating companies. The role blends security architecture with forward-deployed engineering: the Architect both designs secure cloud architectures and embeds directly with cloud, data, and application teams to build and harden secure solutions — including agentic and AI-driven workloads on AWS and Microsoft Azure.

The Architect brings deep, current cloud security engineering expertise and is expected to produce both secure-by-design guidance and working reference implementations. This role complements the broader security architecture function: partnering with the enterprise security architecture team on threat-modeling methodology, framework governance, and cross-OpCo review standards, while providing the deep cloud-platform and data-platform engineering capability to turn those standards into deployed, defensible architectures.

• Combine security architecture with forward-deployed engineering: design secure cloud architectures and embed with cloud, data, and application teams to build and harden secure solutions on AWS and Azure;
• Design and implement secure reference architectures and secure-by-design patterns for cloud workloads, including landing zones, network segmentation, identity, secrets management, and egress control;
• Architect and secure agentic and AI/LLM-driven workloads, including secure integration patterns, API and tool/MCP security, data protection, and guardrails for AI services on AWS and Azure;
• Provide security architecture and hands-on engineering for data-platform workloads, with particular focus on Databricks (Unity Catalog, workspace/network isolation, access governance, and secure app/endpoint exposure);
• Build working reference implementations, automation, and infrastructure-as-code that engineering teams can adopt directly, rather than design documents alone;
• Architect secure patterns for internet-exposed cloud workloads, including WAF, application gateway, private connectivity, and egress controls;
• Partner with the enterprise security architecture function to apply threat models, control baselines, and review standards to cloud and data-platform designs;
• Provide technical guidance and mentorship to cloud and engineering teams, and communicate cloud security risk and posture to senior leadership; and
• Adhere to internal standards, policies, and procedures, and perform other duties as assigned.

Required Education and Experience

• Bachelor's degree in Computer Science, Cyber Security, or a related field, or commensurate experience in cloud security architecture and engineering;
• 7 or more years of relevant IT experience in cloud and application development;
• 5 or more years devoted specifically to security, with deep, hands-on AWS security and Azure cloud security engineering experience;
• Demonstrated experience building and securing solutions on both AWS and Azure (not single-cloud); and
• Hands-on experience building applications or automation, including the ability to develop agentic and AI-driven solutions on AWS and/or Azure.

Preferred Education and Experience

• Master's degree in Computer Science, Cyber Security, or a related field preferred;
• Hands-on Databricks security experience (Unity Catalog, network isolation, access governance, Databricks Apps exposure) preferred;
• Forward-deployed and embedded engineering experience working directly inside delivery teams preferred;
• Experience with CNAPP/CSPM tooling (e.g., Wiz or Cortex Cloud), EDR/XDR (e.g., CrowdStrike), and modern SIEM preferred; and
• Experience in a large, federated, or multi-business-unit enterprise a plus.
