• Apply best practices around security, observability, and cost optimization across infrastructure and services
• Manage and optimize database technologies, with a focus on Amazon RDS and Aurora
• Partner with development teams to ensure seamless deployment and integration of new features and updates
• Investigate and resolve incidents, perform root cause analysis, and implement long-term fixes
• Participate in on-call rotations and provide support for critical production systems
• Contribute to SRE best practices, internal tooling, and team knowledge sharing

• 5+ years of experience in Site Reliability Engineering, DevOps, or related infrastructure roles
• Deep expertise in public cloud platforms, especially AWS, with hands-on experience in services like EC2, S3, Lambda, CloudWatch, and IAM
• Strong proficiency with Kubernetes and container orchestration — you've run production workloads and understand cluster management, scaling, and troubleshooting
• Extensive experience with Infrastructure as Code (IaC) using tools such as Terraform, Pulumi, or Crossplane
• Solid scripting or programming skills in languages like Python, Bash, or Go, with a strong focus on automation
• Excellent problem-solving and debugging skills, with a systems-thinking mindset
• Strong communicator who thrives in collaborative, remote-first teams
• Working knowledge of managed database services like Amazon RDS, Aurora, or PostgreSQL is a plus — but infrastructure is your main game
