Motive is looking for a Sr. Cloud Security Engineer to join our Security Engineering team. You will design and implement secure cloud architectures, build automations, and deploy AWS-native controls to protect our platform at scale. You will work hands-on in AWS, writing code, building guardrails, improving identity architecture, and creating secure patterns for infrastructure teams.

This is a highly technical role for engineers who want to build, not just review—engineers who enjoy designing systems, automating everything, and raising the security bar through engineering excellence.

Architect and implement secure AWS infrastructure patterns (IAM, VPC, KMS, EKS, Lambda, ECS/Fargate, S3, CloudTrail, etc.)

• Write high-quality code (Python, Go preferred) to build automations, tooling, and internal security services
• Build cloud guardrails, AWS Config rules, SCPs, and automated remediation workflows
• Design and implement "secure defaults" and paved roads for engineering teams
• Partner with Infra, SRE, and Application teams to design secure systems and APIs
• Improve least privilege across human and non-human identities through automation
• Build event-driven detections using CloudTrail, EventBridge, Lambda, and Step Functions
• Threat model new services and provide actionable architecture guidance
• Own key domains such as secrets management, container security, and network segmentation
• Drive measurable security outcomes with data and code
  Contribute to documentation, playbooks, and reusable patterns

• Strong cloud security fundamentals (identity, networks, encryption, isolation, boundary design)
• Deep hands-on experience with AWS security services: IAM, KMS, S3, CloudTrail, GuardDuty, Config, Security Hub, VPC, WAF
• Ability to design, write, and maintain automations using Python or Go
• Experience architecting multi-component distributed systems in AWS
• Ability to design solutions end-to-end and break them into executable pieces
• Strong debugging, root cause analysis, and system thinking abilities
• Experience with threat modeling and risk analysis in cloud workloads
• Proven ability to collaborate cross-functionally with Infra/SRE/Product teams
• Ability to self-manage and drive projects from design to deployment
  Strong communication habits and an ability to explain complex tradeoffs cleanly

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