• Drive cloud cost optimization initiatives, identifying opportunities to improve infrastructure efficiency and deliver measurable business value.
• Strengthen observability through monitoring, alerting, dashboards, operational tooling, and proactive identification of reliability issues.
• Participate in on-call rotations, lead incident response, troubleshoot production issues, and drive sustainable improvements through blameless post-incident reviews.
• Support strategic cloud initiatives spanning networking, identity and access management, governance, security guardrails, and multi-account architecture.
• Review technical designs and code, maintain documentation and operational runbooks, and mentor other engineers.
• Leverage AI-assisted engineering tools to accelerate development, automate repetitive tasks, and reduce operational toil.

Requirements:

• 5+ years of experience in Site Reliability Engineering, Platform Engineering, Infrastructure Engineering, or a comparable role supporting production AWS environments.
• Strong Python development skills, with practical experience building automation, services, or infrastructure tooling for production use.
• Hands-on experience with Infrastructure as Code, particularly AWS CloudFormation and/or AWS CDK.
