Senior Product Security Engineer

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/mTLS, key management, and secrets handling.
• Understanding of authentication and authorization patterns in modern applications: OAuth 2.0, OIDC, SAML, RBAC, and ABAC.
• Demonstrated ability to drive cross-functional security initiatives — partnering with engineering, product, and compliance to embed security into roadmaps, influence architectural decisions, and align stakeholders across boundaries.

Nice to Have

• Proficiency in Python, Java, and/or JavaScript for security automation and tooling.
• Container and orchestration security (Kubernetes runtime protection).
• Software supply chain security and artifact integrity verification.
• Experience with bug bounty programs — triaging findings, driving root-cause analysis, and turning results into systemic security improvements.
• Familiarity with compliance and governance frameworks (SOC 2, ISO 27001, NIST 800-53, NIST AI RMF).
• Certifications such as CKS, CISSP, CSSLP, or AI/ML security credentials.

Why Join Us?

• Work on cutting-edge security challenges in a fast-growing company.
• Opportunity to shape and drive product security strategy.
• Collaborative and security-minded engineering culture.
• Competitive compensation, benefits, and career growth opportunities.
