Senior Software Engineer - Backend

Stacklet helps organizations with large cloud estates optimize cost, improve security, and ensure compliance by simplifying and automating all aspects of governance via code. Our company was founded by the creators and maintainers of CNCF's Cloud Custodian, an open-source project used today by thousands of well-known global brands. Our Stacklet Platform is an award-winning governance as code solution that enables teams to identify and remediate cloud governance issues while establishing preventative guardrails against their recurrence. We support some of the world's biggest cloud service consumers, helping mitigate cloud waste and risk on a large scale. Overview As a senior backend software engineer at Stacklet, you'll build the distributed, event-driven services that turn Cloud Custodian into a platform: the GraphQL API our console and customers run on, the pipelines that execute policies across thousands of cloud accounts, and the asset and cost data stores behind them.
