Job summary

Unity, a leader in real-time 3D platforms, seeks a Staff Security Architect to drive secure-by-design across engines, editors, and AI-native products. You will partner with engineering and platform teams to map risk and shape architecture while embedding security into launches from design through release.

You will build hands-on, scalable security tooling and advocate secure patterns for enterprise customers and auditors, influencing across regions and teams.

Qualifications

• 10+ years in security, with substantial time in a security architecture, principal, or staff engineering capacity on complex, large-scale systems.
• Demonstrated high craft in AI security: hands-on architecture or security work on LLM-based products, agentic systems, or AI-assisted engineering workflows.
• Hands-on engineering ability. You build, prototype, and extend systems yourself, and you know when not to over-engineer.
• Strong cloud security depth in GCP, AWS, or Azure, including identity, workload, and CI/CD security.
• Solid command of secure architecture patterns, including what enterprise customers and auditors expect.
• Clear technical communication for both engineers and non-technical partners across regions.

Responsibilities

• Shape security architecture for Unity products and services alongside the engineering and platform teams who own their own designs. Map technical risk, align on a coherent target architecture across those teams, and guide them to secure-by-design outcomes rather than late-stage findings.
• Embed in high-priority product and service launches from early design through release. Ensure security is addressed end-to-end and pull in the right specialists from ProdSec, SecOps, Offensive Security, and Infrastructure Security at the right moment.
• Partner with IT and other functions on the launch, design, and configuration of AI features across our vendor and third-party products, so new AI capabilities are enabled with the right controls, data boundaries, and defaults from the start.
• Set the security architecture for Unity's AI-native products, LLM integrations, agent workflows, and AI-assisted development toolchains.
• Contribute to the security team's own agentic tooling. We are building automation that puts security review, guidance, and detection directly into developer workflows across source control, AI coding tools, and chat.
• Stay comfortable prototyping ideas with a hands-on approach.
• Analyze our risk posture and advise leadership on prioritization: which remediation and risk-reduction investments actually reduce risk to our products.
