Requirements
  • Minimum of a Bachelor’s (Preferred Master’s); preferably Computer Science/Computer Engineering or a related field
  • 8–12+ years in security architecture, application security, cloud security, or a closely related field
  • 3+ years of hands-on experience securing AI/ML or LLM-based systems in enterprise environments, including practical knowledge of prompt injection, data exfiltration through AI APIs, and agentic risk
  • Demonstrated experience defining and implementing AI governance frameworks (OWASP Top 10 for LLM, NIST AI RMF, ISO/IEC 42001, EU AI Act, or equivalent)
  • Strong background in threat modeling, secure design review, and risk management across complex distributed systems
  • Hands-on experience with data loss prevention (DLP), CASB, SWG, or equivalent technologies applied to AI and SaaS environments
  • Experience designing and enforcing granular access control frameworks (RBAC, ABAC) for AI agents, tools, and data pipelines
  • Strong written and verbal communication skills including executive-level reporting and the ability to translate complex AI risk into business language
  • Ability to read and review code (Python, JavaScript/TypeScript, or similar) to understand AI workflows, APIs, and failure modes
Responsibilities
  • Define and own VIAVI's enterprise AI governance framework, translating policy into enforceable technical controls aligned with NIST AI RMF, ISO/IEC 42001, and the EU AI Act
  • Establish and maintain an AI risk tiering and classification system covering data sensitivity, model risk, autonomy level, and business exposure
  • Collaborate with IT, Procurement, and Legal to operationalize an AI tool approval and onboarding process. Build and operate a continuous AI discovery program to identify unsanctioned AI tools, embedded AI features in approved SaaS applications, and browser-based AI interactions across the enterprise
  • Build and operate AI intake workflows to evaluate, approve, and track all new AI use cases, tools, models, and integrations before production deployment
  • Partner with Legal, Privacy, and Compliance teams to define AI exception and waiver processes; support internal audits and regulatory examinations
  • Stay ahead of emerging AI regulations and industry standards including sector-specific requirements and translate them into actionable policy and controls
  • Lead AI-specific threat modeling across the full AI lifecycle covering prompt injection, data leakage, model poisoning, adversarial attacks, tool abuse, privilege escalation, and agentic supply-chain risks
  • Define and enforce secure AI architecture patterns and prohibited design anti-patterns for LLM-powered applications, autonomous agents, and multi-agent workflows
  • Partner with product and platform engineering teams to embed security controls natively into AI development pipelines (S-SDLC / Secure AI Development Lifecycle), including secure CI/CD gates, pre-production reviews, and post-deployment monitoring
  • Design and operationalize runtime protections for AI systems including prompt injection detection, jailbreak protection, output content controls, and abuse detection for high-throughput environments
  • Define Human-on-the-Loop (HOTL) review checkpoints for autonomous agentic workflows where high-risk decisions require human oversight before execution
  • Design and enforce granular data access controls for AI systems, ensuring least-privilege access to tools, data sources, APIs, and enterprise platforms invoked by AI agents; enforce clear segregation of duties across agent orchestration layers
  • Implement data usage monitoring across AI workflows to detect unauthorized data access, over-permissioned AI agents, sensitive data exposure in model inputs/outputs, and policy violations in near-real time
  • Develop and operationalize controls to prevent data exfiltration through AI channels, including prompt-based exfiltration via LLMs, data leakage through RAG retrieval pipelines, and output exfiltration through API integrations and third-party AI services
  • Establish AI-specific data classification policies and enforce data boundary controls, retention limits, and usage constraints for data ingested by or generated by AI systems

Simplify's Take

What believers are saying

  • June 2026 launches like Ultra Ethernet and PCIe 6.0 target AI datacenter spending.
  • Q3 fiscal 2026 revenue rose 42.8%, and operating margin reached 21%.
  • EU funding for SHIELD-6G and Vertex 6.0 strengthen VIAVI's 6G and wireless pipeline.

What critics are saying

  • January 2026 cuts hit 5% of staff, signaling margin pressure and integration strain.
  • If Spirent synergies miss plan, the $425 million acquisition destroys capital through 2026.
  • A telecom capex slump or AI-test cycle break leaves VIAVI trapped in low-growth hardware demand.

What makes Viavi Solutions unique

  • VIAVI owns 3,400-plus patents and deep test IP across telecom, optical, and security.
  • Its Spirent deal adds channel emulation and high-speed Ethernet depth since October 2025.
  • VIAVI ships compliance-grade platforms, including PCIe 6.0 and Vertex 6.0, for standards-led buyers.

Merck's strong 21.5% cash flow margin contrasts with Allegro and Viavi's struggles

StockStory analysed three cash-producing stocks, recommending investors avoid two while highlighting one with stronger prospects. Allegro MicroSystems faces end-market challenges, with flat sales over two years and operating margin falling to 2% over five years. The power management chip designer trades at 37.6x forward P/E. Viavi Solutions showed weak performance with 3.4% annual growth over five years, whilst earnings per share remained flat despite revenue growth. The telecommunications testing company trades at 26.2x forward P/E. Merck emerged as the recommended stock, boasting a 21.5% trailing 12-month free cash flow margin. The pharmaceutical company's portfolio includes the blockbuster cancer immunotherapy Keytruda. The analysis emphasises that strong cash flow alone doesn't guarantee superior returns without efficient capital allocation.

VIAVI secures $1.1M EU funding to develop AI-driven security testing for 6G networks

VIAVI Solutions has been awarded $1.1 million in funding from the European Smart Networks and Services Joint Undertaking and Horizon Europe to advance the SHIELD-6G project. The company will develop digital twins using its TeraVM AI RAN Scenario Generator, enabling AI-driven security models to be tested before commercial 6G networks launch. The SHIELD-6G project aims to create a comprehensive AI-driven cyber threat intelligence platform for 6G networks. VIAVI will use its technology to simulate, detect and analyse potential threats across network environments. VIAVI joins a European consortium coordinated by University College Dublin, working alongside Ericsson, Nokia, Thales and network operators Telefónica and LMT of Latvia. SHIELD-6G is part of Horizon Europe's initiative to accelerate European 6G research, which selected 20 new projects.
