About the Role We're looking for a Senior Product Security Engineer to lead the design and implementation of secure, scalable, and trustworthy products across AlphaSense's AI-native platform. You'll work closely with architects, engineering, and product teams to embed security by design throughout the software development lifecycle. This role sits at the intersection of AI/ML security, secure architecture, threat modeling, and customer-facing assurance — defining the standards, automation, and frameworks that enable secure, intelligent products at scale. What You’ll Do: AI Security & Enablement (30%) • Architect and enforce security controls for AI/ML systems — model training, data pipelines, inference environments, and agentic workflows. • Identify and mitigate AI-specific attack vectors: prompt injection, data poisoning, model inversion, model theft. • Implement model provenance, integrity, and auditability controls for responsible, secure AI operations. • Align AI security with governance and compliance teams against frameworks like NIST AI RMF and the EU AI Act. Secure Architecture & Development Lifecycle (30%) • Embed security throughout the software and AI development lifecycle, partnering with architects, engineering, and product across AlphaSense's application and cloud ecosystems. • Ensure security, privacy, and compliance by design. • Define and maintain secure development standards, guidance, and best practices. Threat Modeling & Security Review (20%) • Lead threat modeling, secure design reviews, and risk assessments across the software development lifecycle. • Build and maintain security automation and governance that integrates into development workflows. Customer-Facing Security Assurance (10%) • Produce customer-facing security assurance — security questionnaire responses, security whitepapers, and trust collateral — that unblocks enterprise deals. • Represent product security in customer, cross-functional, and leadership discussions. Leadership (10%) • Mentor teams on secure coding, AI risk management, and secure design. • Promote a security-first culture through advocacy, documentation, and training. What We Are Looking For: • 5–7+ years in product, application, or cloud security engineering. • Deep understanding of secure SDLC, threat modeling, and secure architecture design. • Ability to read and review code to inform threat models and design reviews. • Experience securing AI/ML pipelines, data workflows, and model-serving infrastructure, with working knowledge of AI/LLM security (prompt injection, model integrity, provenance). • Proven expertise with cloud security concepts and best practices across multi-cloud environments. • Familiarity with DevSecOps and CI/CD environments. • Familiarity with encryption fundamentals — symmetric and asymmetric cryptography, TLS/mT
