What you'll do
We're looking for an AWS Cost Optimization Specialist. At Clara, our infrastructure is the backbone of our financial services, and managing it efficiently is key to our scalability and unit economics. You will design and execute Clara’s AWS cost optimization strategy, moving beyond simple monitoring to proactive financial engineering.

Strategy & Analysis: Design and execute the global AWS cost optimization strategy, continuously identifying savings across EC2, ECS, and Aurora clusters.
-
Governance & Tagging: Implement standardized tagging strategies for precise cost allocation by domain, squad, country, and product.
-
Infrastructure Optimization: Optimize AWS Kafka clusters, OpenSearch storage strategies, and networking/data transfer costs to ensure lean operations.
-
FinOps Automation: Define and implement automated shutdown policies for non-production environments and configure advanced anomaly detection and budget alerts.
-
Data & Dashboards: Build executive and operational dashboards using AWS Cost Explorer, Athena, or QuickSight to provide real-time visibility into cloud spend.
-
Architectural Partnership: Partner with engineering teams to design cost-efficient architectures and establish long-term cloud financial governance standards.

Clara’s Hybrid Policy
Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team.
We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
