Infrastructure Security Engineer

As an Infrastructure Security Engineer, you'll design, build, and operate the security platforms and controls that protect Wix's production infrastructure at scale - from Kubernetes clusters and cloud environments to identity and secrets management. You'll work across multiple security domains, building systems that enforce policy, detect threats, and give engineering teams secure-by-default guardrails. In your day-to-day, you will: Design, build, and operate supply chain security controls - governing what software and dependencies enter our production environment Own and evolve our secrets and identity management infrastructure, including policy lifecycle and multi-environment operations Build policy-as-code frameworks and continuous compliance enforcement across Kubernetes, IaC, and cloud environments Deploy and manage runtime security and detection tools, and build automation for incident investigation and response Design and ship infrastructure changes across multiple data centers and cloud regions, collaborating with infrastructure teams on security, reliability, and cost alignment Leverage AI-assisted engineering workflows across your work - from design and implementation to debugging, code review, and security operations. We use AI as a daily force multiplier, not an afterthought 5+ years of experience in infrastructure engineering, platform engineering, or security engineering in production environments Proficiency in at least one modern programming language (Go, Python, Java or similar). We work across multiple languages and use AI to move fast - what matters is engineering fundamentals, not a specific language Hands-on experience with Kubernetes (operations, policy enforcement, networking) and at least one major cloud platform (AWS or GCP) Experience with Infrastructure-as-Code tools (Terraform, Helm) and managing infrastructure at scale Solid understanding of network security, IAM/RBAC, and cloud security fundamentals Ability to design and build systems - not just operate them. We need engineers who think in platforms Strong collaboration and communication skills - you'll work across infrastructure, security, and product teams We are Wix's Infrastructure Guild. We're at the core of building and maintaining the production and CI/CD environment. Our mission is to improve production performance, security, and resilience to ensure 99.99% uptime for millions of users and drive our developer velocity. We design, develop, and operate cutting-edge technology and robust tools to service Wix's Infrastructure needs
