Responsibilities

You’ll lead and execute cloud security initiatives that strengthen Webflow’s infrastructure and operational security posture. Responsibilities are grouped by scope and impact.

  • Design, implement, and maintain secure AWS infrastructure following best practices (least privilege, network segmentation, encryption, monitoring).
  • Partner with infrastructure and platform teams to embed security controls in CI/CD pipelines, infrastructure as code, and containerized environments.
  • Own the cloud security posture management (CSPM) strategy, ensuring continuous compliance and automated detection of misconfigurations.
  • Evaluate and deploy security tooling for cloud visibility, IAM governance, and intrusion detection.
  • Collaborate with engineering teams to secure Kubernetes and containerized workloads, ensuring adherence to runtime and image scanning policies.
  • Respond to and investigate cloud-related security incidents, providing technical expertise during triage and remediation.
  • Contribute to the design and execution of Webflow’s cloud security roadmap, identifying areas for automation and scalability.
  • Conduct threat modeling and risk assessments for cloud architecture and new service deployments.
  • Develop internal tools and scripts to enhance cloud monitoring and detection capabilities.

  • Can script or automate security tasks using Python, Go, or Bash.
  • Communicate clearly and collaborate effectively across security, DevOps, and product teams.

  • Familiarity with secrets management solutions 
  • Knowledge of threat detection and response in serverless or containerized environments.
  • Contributions to open-source security tools or participation in cloud security communities.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
