The Principal Software Security Architect owns security architecture for Beyond Trust's product suite end to end, including endpoint agents, thick clients, Saa S platforms, APIs, identity systems, and cloud-native servicesThis is an engineering leadership role embedded within Engineering and Architecture teams in the Office of the CTO, accountable for designing security into products from first principles through to what ships and runs in production, rather than reviewing other teams' work from the outsideWe operate AI-first: Claude and LLM-driven workflows are how the team performs threat modeling, secure design reviews, vulnerability analysis, and developer enablement today, and this role is expected to operate at that level from day one and help extend that practice furtherOwn end-to-end security architecture for assigned product lines, from concept through production, defining the target-state architecture and secure-by-default patterns each product builds onLead threat modeling, attack surface analysis, and secure design reviews across products, platform services, endpoint agents, and cloud-native systems, driving the architectural decisions that eliminate unnecessary exposure rather than just documenting riskUse LLM platforms (Claude, Open AI) as core tools to scale threat analysis, abuse-case generation, architecture review, and remediation guidance, building the prompts, plugins, skills, and agent workflows that make the engineering org faster and more consistentEmbed secure-by-default patterns directly into product development, contributing reference architectures, reusable components, and automated guardrails,



and building self-service security capabilities that let engineers make secure decisions without a bottleneckOwn and expand the Product Security handbook, a living system that feeds the team's AI workflows to enforce secure design standards, architecture guidance, and engineering best practicesSet technical direction for secure design across the org as a principal-level engineer, mentoring engineers, architects, and Security Champions on secure design, attack surface reduction, and AI-first security workflowsHelp evolve Beyond Trust's AI-first Product Security Architecture strategy, identifying where AI workflows can replace manual processes, where they need human oversight, and where the next capability gaps areWhat Success Looks Like:Measurable reduction in product attack surface and recurring architecture risks, measured by risk eliminated, not findings producedSecurity architecture for owned product lines is defined, documented,



and demonstrably adopted in shipping productsIncreased scale and consistency of secure design reviews through AI-first workflowsFaster identification and remediation of design-level and architecture-level risksEngineering teams actively using self-service security capabilities that have been builtExpansion of AI-first Product Security Architecture capabilities across the SDLCThe ideal candidate brings 10+ years of hands-on software engineering and security architecture experience, deep expertise in threat modeling and attack surface reduction at scale, and practical experience applying LLM platforms to security engineering work Ability to influence engineering and product teams from within, acting as a persuasive, credible, and practical partner rather than a gatekeeper Deep, practical experience with threat modeling, attack surface analysis, secure design reviews, and architecture risk analysis at scale, not just in theory Strong hands-on engineering background, with the ability to read and contribute to the codebase, design systems, and earn credibility with senior engineers as a peer Solid understanding of cloud-native systems, APIs, endpoint agents, thick clients, and identity/security platforms Experience building AI-native security workflows, plugins, agents, or developer tooling Hands-on experience using LLM platforms (Claude, Open AI, or similar) in engineering or security workflows Builder mindset, having created scalable security workflows, frameworks, or enablement programs, not just consumed them10+ years in Software Engineering, Security Architecture, Product Security, or Application Security, with a track record of owning architecture for shipping products Offensive security experience or adversarial testing background Background in securing endpoint technologies, identity systems, or enterprise security platforms Cloud security experience across AWS, Azure, or Kubernetes environments#J-18808-Ljbffr
