- Establish and lead internal knowledge-sharing practices (brown bags, runbooks, documentation standards, onboarding guides) to raise the team's overall DevOps maturity
- Set technical standards and best practices for infrastructure code, container builds, and pipeline design, and hold the team accountable to them through review and coaching rather than top-down mandate

- Design, build, and continuously improve CI/CD pipelines that automate build, test, security scanning, and deployment of containerized applications to ECS
- Implement deployment safety mechanisms: automated testing gates, canary/blue-green deployments, rollback automation, and release approvals
- Collaborate with security and compliance teams to ensure infrastructure and pipelines meet applicable security baselines and, where required, support Assessment & Authorization (A&A)/RMF documentation for infrastructure components
- Participate in on-call rotation and incident response for infrastructure and deployment-related issues; drive blameless postmortems and follow-through on action items
