Sr. Cloud Security Engineer

Motive is looking for a Product Security Architect to join our Security Engineering team. You will be the primary security partner for product and engineering teams, focusing on design reviews, threat modeling, and building scalable "secure-by-default" components (libraries, services, frameworks) that empower engineers to ship securely and quickly. You will work across teams, influencing architecture and driving enablement programs.

This is a highly strategic and technical role for architects who want to scale security through programs, influence, and engineering excellence, focusing on design, automation, and enablement.

What you’ll do:

Lead security design reviews and threat modeling for critical new products and features.Partner directly with Product and Engineering teams to define security requirements and architecture.Design, develop, and advocate for secure-by-default libraries and frameworks that eliminate entire classes of vulnerabilities.Develop and lead a Security Champions program to embed security expertise within product engineering teams.Provide expert guidance on architecture patterns (cloud, container, API, identity, data) to ensure security is built-in, not bolted on.Review 100s of features being shipped every quarter, identifying high-risk areas and prioritizing engagement.Drive measurable security outcomes by scaling engagement with dev/eng teams while keeping the security team lean.Own key domains such as API security, authentication/authorization patterns, and data-in-transit/at-rest security.Contribute to documentation, playbooks, and reusable patterns.

What we’re looking for:

Strong background in Product Security principles, architecture, and design patterns (API security, modern auth/auth, data security).Proven ability to lead security design reviews and threat modeling for large-scale distributed systems.Experience designing and developing secure-by-default libraries, frameworks, or security services for internal consumption.Deep hands-on experience with cloud security fundamentals (identity, networks, encryption, isolation, boundary design).Ability to design, write, and maintain automations using Python or Go is a plus, but architecture skills are paramount.Excellent cross-functional collaboration and communication skills, with a track record of influencing engineering and product decisions.Experience establishing or running a Security Champions program or similar security enablement initiatives is a strong plus.Ability to self-manage, think strategically about security program scaling, and drive projects from design to deployment.

Bonus skills:

Experience with Kubernetes/EKS, ArgoCD, or Terraform.Experience with multi-account AWS Org design.Experience with CI/CD security and software supply chain controls.Experience with IoT or edge device security.Experience building identity automation or least privilege workflows.
