About This Role

Defining the architectural "North Star" for cloud-native platforms, ensuring they are secure by design, is at the core of this Principal Security Architect role. This high-impact position involves driving complex threat modeling, steering architectural direction across multiple cloud providers, and partnering with engineering leadership to embed security deeply within next-generation products.

Responsibilities

• Define and maintain the authoritative security architecture patterns for services across multi-cloud environments, including GCP, AWS, Azure, OCI, and SAP
• Lead the design of secure, scalable, and resilient systems by championing 'Security by Design' principles such as isolation, identity management (IAM), and data protection
• Drive the architectural strategy and implementation of Zero Trust principles across development environments and production SaaS platforms
• Own the organization's threat modeling methodology, facilitating deep-dive sessions for critical features to identify attack vectors in complex distributed systems
• Translate architectural risks into actionable items for the Cybersecurity Risk Register, effectively communicating the business impact to leadership
• Serve as a subject matter expert on security products (CWPP, CSPM, NGFW), advising product teams on architecting solutions to withstand modern adversary TTPs
• Provide high-level technical guidance and mentorship to Staff and Senior security engineers, fostering a culture of engineering excellence and proactive security
• Lead cross-functional 'Tiger Teams' through complex security implementations, acting as the bridge between Developer, Product Engineering, and InfoSec teams

Requirements

• 8+ years of experience in security engineering and/or security architecture, with at least 4+ years in a Principal or Lead capacity
• Deep, hands-on architectural expertise in at least one major public cloud provider (GCP, AWS, Azure, OCI, or SAP) with a strong working knowledge of the others
• Demonstrated sophisticated, deep knowledge and hands-on experience with modern Secure-by-Design, Privacy-by-Design, and Zero Trust principles and practices
• Proven track record of executing complex threat models (e.g., STRIDE, PASTA, DREAD) for microservices and serverless architectures
• Proficiency with a scripting language such as Python or Go and experience securing CI/CD pipelines

Nice to have:

• Experience securing AI/ML ecosystems, with a deep understanding of adversarial machine learning attacks and defenses for Large Language Models (LLMs)
• Deep understanding of the security vendor landscape, with experience designing or using CSPM, CWPP, or Container Security platforms
• Exceptional ability to communicate technical risk to executive audiences and negotiate architectural trade-offs with product owners
• Experience with well-architected frameworks (AWS, Azure, GCP) and their security pillars
