Responsibilities

Box has a world-class security organization responsible for protecting our customer and employee data around the globe. We are looking for a Senior Enterprise AI Security Engineer to join our Enterprise Security team and own how Box adopts AI internally - safely, quickly, and at scale.

• Design, build, deploy, and maintain comprehensive security systems that allow Box's workforce to use AI tools and agents productively without losing visibility, identity boundaries, or control of company data.
• Architect and operate the control plane for workforce AI: AI gateways, prompt and response logging, and egress controls across approved assistants and copilots/agents.
• Extend identity and access management to agentic and non-human identities.
• Gate what internal agents can reach: an approval path for MCP servers and connectors, scoped permissions per tool, and isolated execution for anything that runs code.
• Harden the AI-era endpoint and browser layer: enterprise browser policy, extension governance, AI-assisted developer tooling, and local agent runtimes.
• Build the shared enforcement layer that catches risky behavior in flight: injected instructions, attempts to talk around a restriction, tools used outside their intended purpose, sensitive data heading somewhere it should not, and agents behaving nothing like they did last week.
• Lead security architecture reviews and threat modeling for AI vendors, AI features enabled inside existing SaaS platforms, and internal agent deployments.
• Own the standards, reference architectures, and paved paths that define what approved AI usage concretely means at Box, and build reusable patterns.
• Partner with IT, Infrastructure, Incident Response, Engineering, Legal, and Privacy to mature AI governance, including AI-specific response playbooks.
• Automate through scripting, infrastructure-as-code, and orchestration instead of manual review queues, and bring AI-assisted investigation tooling to the security team itself.
• Help raise the technical bar across the team through design and code review, mentoring, and guidance.

Requirements

• Bachelor's or Master's degree in computer science, information security, or a related field, or equivalent practical experience.
• 6+ years in enterprise or corporate security engineering, security platform engineering, application or product security, or a combination - with meaningful recent time spent on AI or agentic systems.
• Hands-on experience securing real AI deployments - enterprise assistants, internal agents, and the tool ecosystems around them, grounded search or RAG over company data, or AI coding tools inside a developer environment.
• A working mental model of how AI systems get abused and paired with the ability to analyze AI workflows to determine guardrails.
• Strong identity and access management fundamentals.
• Experience with security automation in Python, Go, or a similar language, and a track record of building tooling, libraries, or platform controls.
• Fluency in the emerging problems of this space: shadow AI, agentic and non-human identity, SaaS-to-SaaS integration risk, browser security, and data exfiltration paths.
• Exceptional communication skills, with the ability to explain AI risk and its business impact to practitioners.
• Proven ability to work independently with autonomy, manage ambiguity, and recommend secure but risk-profiled decisions.

Nice to Have

• A track record of shipping internal security platforms.
• Exposure to isolation and permissioning for autonomous workloads, or to AI red teaming and evaluation work.

We Offer

• Competitive salary range: $190,000-$263,000 USD.
• Equity and benefits.
• Generous time off, birthday holidays, VTO, and a sabbatical after seven years.
• Growth opportunities through learning programs and clear career paths.
• Evolving workplace with hybrid work options.
• Global, inclusive benefits including mental health, wellbeing, and family support.
• Paid parental leave, fertility, and family-forming benefits.
• Fresh Air Days and a monthly wellness subsidy for fitness.
• Community involvement through employee-led resource groups, interest groups, global virtual events, and paid volunteer time off.
