Senior Engineer, AI Cyber Security

About This Role

As Biogen's AI Security Engineer, you are a hands-on technical specialist responsible for securing the organization's rapidly expanding use of artificial intelligence, machine learning, and generative AI technologies. This role operates at the intersection of cybersecurity engineering and AI/ML systems — ensuring that AI deployments across Biogen are resilient against adversarial threats, data poisoning, model manipulation, prompt injection, and unauthorized data exposure.

The AI Security Engineer will design, implement, and operate security controls purpose-built for AI workloads — spanning model development pipelines, inference endpoints, training data protection, and AI-assisted automation platforms. This role is responsible for translating emerging AI threat frameworks (MITRE ATLAS, OWASP AI Top 10, NIST AI RMF) into actionable engineering controls that protect Biogen's AI investments without impeding innovation velocity.

This position requires a rare combination of software engineering depth, AI/ML systems knowledge, and cybersecurity expertise. The scope demands:

Deep technical proficiency across AI/ML security, cloud security, and application security — with the ability to build production-grade security tooling, not just assess or advise

Autonomous execution — independently identifying AI security gaps, designing solutions, and implementing them end-to-end without requiring constant direction

Adversarial mindset — thinking like an attacker to…
