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

At Wix, we believe our best work happens together. Our work model is fully in person, with 5 days a week from our office. Flexibility remains a core value at Wix and special requests are handled thoughtfully at the team level.

 

• 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
