• Build AI-powered observability solutions with intelligent guidance, pattern recognition, and predictive incident response for distributed environments.
• Lead platform reliability initiatives including automated rollbacks and zero-touch operations for standard workflows.
• Implement enterprise networking, security policies, and cost optimization strategies with automated governance and compliance.
• Design and scale AI platform infrastructure for SaaS products, supporting both internal operational needs and customer-facing AI/ML features and requirements.
• Mentor engineers while driving platform adoption through evangelism, and product management principles.

Qualifications

• BS/MS in Computer Science, Engineering, or related field, or equivalent experience.
• 8+ years in DevOps, SRE, Platform Engineering, or Cloud Architecture roles, with proven leadership and product ownership experience.
• Expert-level cloud architecture experience across GCP, AWS, and Azure, including enterprise networking and distributed systems at scale.
• Mastery of modern platform technologies: Kubernetes, Terraform, GitOps (ArgoCD/Flux), service mesh, and RBAC/IAM frameworks.
• Strong programming skills in Go, Python, or Node.js; experience building developer portals (Backstage) and AI/ML-powered tooling.
• Proven track record implementing intelligent operational systems, monitoring, and distributed tracing solutions.
• Experience with cloud governance, FinOps optimization, networking security, compliance frameworks, and deployment automation (canary deployments, feature flags).
• Excellent communication and mentoring skills; understanding of DORA metrics and data-driven platform improvement methodologies.
