Senior Security Engineer

We are looking for a Senior Security Engineer to join our Product and Enterprise Security team, based hybrid out of our Tacoma, WA office and reporting to the Security Engineering manager. Security is a revenue enabler at Infoblox: our products run inside 70% of the Fortune 500, and those customers need to trust the infrastructure behind them. In this role you will own security engineering end to end across that infrastructure, from cloud and Kubernetes environments to the network edge, identity systems, and endpoints.

You will design, deploy, and harden the controls that protect Infoblox and our customers, and automate that work through infrastructure as code and security tooling so it scales across a fast-growing, multi-cloud estate. This is a newly expanded function, so you will help shape how it is built, not just operate what already exists. AI-assisted automation is a growing part of how we work, and we value engineers who use it thoughtfully while understanding what's happening under the hood.

You are the ideal candidate if you're an infrastructure-minded security engineer with deep expertise in two or three of the areas below and working knowledge of the rest. You like seeing the whole picture, enjoy turning recurring problems into automated, repeatable solutions, and can partner effectively with engineering, IT, and operations teams to raise the security bar without slowing them down.

Be a Contributor — What You’llDo

• Own the design, implementation, and hardening of security controls across our cloud, Kubernetes, network, identity, and endpoint infrastructure
• Deploy, tune, and operate cloud security and CSPM platforms such as Wiz across AWS, Azure, and GCP, and drive remediation of misconfigurations and exposures with engineering teams
• Secure the network edge by managing WAF (e.g., Fastly), DDoS protection, network segmentation, and firewall policy for internet-facing and internal services
• Advance our identity and Zero Trust strategy, including least-privilege IAM, SSO and MFA enforcement, privileged and non-human identity management, and emerging agentic AI identity patterns
• Own and manage our EDR platform (e.g., Crowd Strike) across endpoints and cloud workloads, including deployment, policy tuning, coverage, and sensor health, and partner with the SOC on the telemetry and detections they rely on
• Build and maintain security automation and guardrails as code, using Terraform, CI/CD pipelines, and…
